I’ve been training with Coach Peter at Impact Metrowest since March 2024, and it’s been an incredible experience. I started going by myself, but over time I brought my wife and two kids — now it’s become a family thing we all look forward to. Peter is an amazing coach: knowledgeable, motivating, and always focused on helping you get stronger and healthier. He also emphasizes healthy eating and overall wellness, not just workouts.

The whole team is fantastic — Tiff and Zach are awesome coaches who bring great energy and support every time we’re in the gym. You can tell everyone here genuinely cares about helping you reach your goals. Highly recommend!

Peter and all the coaches really listen to their clients and give 100%! I am in my late 50s and pretty active but was dealing with so much arthritis pain that was limiting movement in my daily life. It’s been about 6 months working with coach Peter and I have been able to get back to hiking and running and anything that I want to do. I am even going to try my first Hyrox event next month. The training programming at Impact has set me up to so much stronger, balanced and mobile!

I’ve been training at Impact Metrowest for over three months, and they’ve absolutely delivered. Peter and his team know their stuff.

I’m in my 40s with very little prior gym experience. After spending much of the past year in physical therapy and specialist visits for worsening lower back pain, I was determined to rebuild my strength, not just to manage pain, but to make fitness enjoyable and sustainable.

I’ve primarily trained 1:1 with Tiff, who’s phenomenal - knowledgeable, motivating, and an absolute joy to work with. She pushed me to train harder while catching subtle strength imbalances, often aligning (and even going beyond) what my PT and doctor had previously identified. I’ve also trained with Peter and Zach, who each bring their own expertise and attention to detail. They’re approachable, encouraging, and truly invested in helping you improve. Most of their clients have been training here for a long time, and it’s easy to see why.

Three months in, I’m noticeably stronger, and my lower back pain has improved dramatically. More importantly, I’ve gained confidence and I'm building a mindset that I want to get stronger not just to avoid pain, but because I can.

If you’re on the fence, don’t overthink it. Just go for it. It’s absolutely worth the investment.

Impact Metrowest has been such a wonderful and welcome experience! Over the past few months, I have been able to work with Coach Peter, Zach, Tiff, and Ryan, and they have each helped me become stronger while focusing on my overall health. Everyone at Impact really does care about how you are doing, and they push you to be the best version of yourself that you can be. I cannot recommend this place enough.

Coaches Peter, Tiffany and Zach have shown themselves to be exceptional instructors and I am so glad that I joined Impact a month and a half ago!

I appreciate their knowledge, patience, encouragement, willingness to work with each student to modify workouts if needed, constant advice, and steadfast dedication to what they do.

Coach Tiffany’s nutrition group has been wonderful and staying on point with it has made my body feel so good! This along with the workouts 5 days/week have truly helped my body be healthiest it’s been so far. In addition, Coach Tiffany is so wonderful at really giving students that special attention to make sure we are training correctly. She’s loving but tough!

Coach Zach is the one I spend the most time with as I go to 3 of his classes her week and they are awesome! He’s very encouraging and helps me through difficult moments during the workouts, which I truly appreciate. He’s knowledgeable and makes sure that we are each doing our best. His positive attitude is contagious and gets us through the workouts!

Last, but certainly not least, thank you to Coach Peter for being so accepting of how we all show up to class, I value that very much. Thank you for sharing your knowledge (with your emails!) and really showing a high level of care for all your students. And your Jordan is the icing on the cake!

The group classes are small and while each Coach brings his/her own personality and style to the training, they complement each other very well. The feeling I get after I am done with each class is what keeps me coming back!

All my gratitude to these Coaches!

I enjoyed my previous gym and thought I was getting good instruction in the small group training sessions. However, staffing changes and inconsistent class schedules led me to look for a new gym. Since joining Impact I’ve blown away by the dedication and knowledge of Coach Tiff, Zach and Peter. Impact group training is head and shoulders above what I had experienced! The individual attention and coaching even when in a class with 6 to 8 others is truly amazing. They know their stuff and you can be sure your form is spot on! A bonus is that everyone is welcoming and friendly! Come for the training. Stay for the community!

I have been involved in fitness for over 25 years in a variety of activities, from martial arts to sports to strength training. I walked in 1.5 yrs ago very skeptical, just needing a place to get my head and health right.

Over time, Coaches Peter, Tiff, and Zach demonstrated their commitment to be the best in the business. Their knowledge base, teaching skills, and work ethic is inspiring. Their focus on functional strength, mobility, and explosiveness training was exactly what I was needed (though I didn’t know it at the time). The small class settings combine the value of personal training with the joy of being part of a community. I’ve made friends with common interests and tease the coaches about their insta posts.

They set up a training structure in which everyone can follow and adjust based on their individual needs. When I wanted to focus on upping my deadlift/sqyats, they customized a program just for me. If I miss a day, they text to ask me if everything’s ok!

In conclusion, the team here at Impact MetroWest has done nothing short of helping me to be the best version of myself. They have helped me build strength, power, coordination, and most of all resilience to both physical and mental issues. I’m very grateful to the team here and want to make sure you (the future teammate), know how great they are.

I was looking to get back into my fitness journey after sustaining a severe nerve injury in my right leg. The Coaches at Impact welcomed me with such enthusiasm and encouragement I knew right away this was the place for me. In the group training sessions, they took the time to modify exercises and movements for me to help build a strong foundation that I could continue to progress from. About 10 months later I am lifting heavier than I ever imagined, and moving not only in the gym, but in life virtually pain free and better than I ever have. The Coaches here provide not only advice on how to progress fitness-wise, but also with your nutrition, breathing, sleep, and your general well-being. On top of the amazing Coaches, the other members in the gym have become amazing friends, and even more amazing supporters. The Coaches and other members make for such an amazing environment, it's hard to stay out of the gym! If you're looking for some spectacular and highly educated Coaches to push you beyond what you think your limits are, this is the place for you!

I joined Impact in August of 2024. I figured I would give it a try after taking an assessment with coach Peter. His knowledge and approach seemed very different from other gyms. It takes a lot to exceed my expectations, but Impact has done exactly that. This gym will transform the way to live. I have had back issues all my life, and not once did any trainer talk about the connection between hip mobility and back pain. After only a month my back was pain free and I was seeing drastic improvements in my overall physical shape. Impact is not a place where you just work out, they will help you with nutrition and physical limitations. They truly care about your overall health, which is refreshing in the current world we live in. It's been 6 months now since I have joined Impact, and I'm in the best shape of my life. This is not just a gym it's a community that truly cares and supports each other. If you're thinking of joining I can confidently say you will not regret your decision.

I was very hesitant and indecisive about changing gyms but three months ago I decided to make the change and it is one of the best decisions I have ever made. Coach Peter, Tiff, and Zach all welcomed me right away and have been the best coaches/teachers I have had. They are all so patient in showing me how to do certain exercises the right way without making me feel insecure. I already see a difference in body and my confidence. Walking into Impact is like walking into a family members home. I highly recommend Impact Metrowest to anyone looking for the right gym!

I've always been active -- whether I'm doing landscaping work out in the yard, playing soccer or splitting wood for the winter. But, when I hit my 40s, I have struggled to play a full season of men's recreational soccer without injury and often have some weird pain after doing other strenuous activities.

Since joining IMPACT, some chronic pains have gone away and I'm feeling more stable and flexible than ever. What I was missing was working on strength, balance and coordinated compound body movements.

I have joined and gone to other gyms before, even did guided exercise routines at home, but IMPACT's program has given me the flexibility and movement that free weights and weight machines didn't.

Even after training as a collegiate athlete, I never really learned the right form for many exercises... until IMPACT. The trainers at IMPACT pay close attention and make sure our form is correct as classes proceed.

I'm looking forward to getting back out on the soccer pitch in the spring faster and stronger than ever.

My name is Terry Camara and War Dog’s wrestling club is my gmail account. Impact MetroWest is a 5 star training center designed for all ages.

If you’re looking to get in shape and lose some weight, Impact MetroWest is the place to train. I’ve been a member for 3 years now and I love the family atmosphere they’ve created along with top notch training and nutrition programs that are available to me. Coach Peter along with Coach Tiff and Zach are fired up and alway looking to improve my mobility and health.

I’ve tried many diets over the years and lost weigh, but gained it back. The past two months, I decided to try the individual nutrition program with Coach Tiff. She has helped me with creating a meal plan that is designed around the foods I like while introducing new foods that have helped me lose weight while gaining muscle. I’ve I lost 15 lbs so far, I feel amazing and look amazing. I’ve learned how to eat right while still being able to treat myself on the weekends. Most importantly, I have learned how to maintain my weight which had been so helpful. Thanks to my coaches, I look forward to my 3rd phase which is to lose 10 more lbs so I can reach my goal of losing 25 lbs.

Come train with the best!!!

My partner and I started going to this gym about 7 weeks ago and the transformation has been nothing short of amazing! I started with sore knees and the coaches are slowly helping me to build muscle mass around my knees so I can lift more and live life without knee pain - it's working and I'm seeing improvements with every session. I'm eating healthier and feeling increased confidence as I trade body fat for increased muscle mass. My headspace is better than it's been in the past 2 years as result of the work I'm putting in at the gym and I feel incredible support by the coaches to continue pushing myself in the gym even with a knee injury to work around. This gym is my new found community and I'm so happy to have found it. I've never smiled more while working out than I have here! Seriously, it's that good. Thank you coach Peter, Tiff and Zach for the continued support in helping me reach my fitness goals! I'm so excited to see my progress 6 months from now!

This place is truly awesome! I come train with Coach Peter every single week and its lifted my physical health, mental health, and emotional and spiritual health. These coaches are unlike others in the sense where they promote much more than just the exercise itself. They tell me whats going on with the body, down to the specific muscles and engrain that everything is connected from the hip to the knee to the ankles. They truly love their job and I can see that through the dedication to go to workshops out of town and come in and use those techniques to further help their clients on a daily basis. So hardworking! I love the knowledge they have on the exercises they are teaching, I'm never doing a workout without knowing how its helping me. It's truly been a life changing experience, I am able to build such a great relationship with the coaches and its been such a source of happiness for me! Definitely check out Impact Metrowest!!

I cannot say enough about Impact. Coaches Peter, Tiff, and Zach bring an absolutely tremendous amount of knowledge, energy, inspiration, and motivation to their work. In small group classes, they know each client, give specific feedback about form and the why behind the exercises they recommend. Most importantly, it is clear that this is not "just a job" for them - it is a passion and their commitment is unparalleled. I have been to many gyms in my time and nothing else even comes close.

I cannot express enough gratitude for Coach Peter's guidance in my journey to loose 18 lbs and find myself. As his life partner, he never imposed his knowledge or tried to take on the role of my coach. Instead, he patiently waited until I came to him with questions, always offering support when I needed it.

One pivotal moment was when I asked him why I was gaining weight despite doing everything right, such as never changed on my diet and had a very active lifestyle such as pilates and yoga five times a week. His response was simple yet transformative: "It’s all about the nutrition. As we age, doing the same thing that you did before no longer works.” That advice shifted my focus, and with his encouragement, I installed a food journaling app to track my intake and activities. It was a game-changer, opening my eyes to the importance of nutrition and the little things that mattered in my diet. For example, my coconut water that is only 110 calories a bottle does add up if I take 2 a day, in addition to my coffee. That was really helpful in achieving my goals.

Over the course of 2.5 months, I lost 18 pounds—a feat I wouldn’t have achieved without his subtle yet profound support. He never told me what to do, but his insights and encouragement helped me succeed on my terms. Thank you, Coach Peter, for your wisdom and patience. You made a world of difference in my journey!

Words cannot express the gratitude I have for the team at Impact Metrowest! Coaches Peter, Tiff and Zach are all AMAZING humans who always bring the motivation and inspiration to get you moving and improving. No matter what your goals or needs are when it comes to health and fitness, they help guide you and strive to help you get and feel better every single day! I have a physically demanding job and need my body working and feeling as best it can. I've been through two back injuries and a shoulder injury, and each time, they were my first calls on how to get back to lifting heavy. Tailoring workouts, offering modifications, guiding you with nutrition, recovery, and life, they do it all here! I just set a new personal best for kettlebell front squats last week, so there's proof in their methods! Coach Peter's passion and drive will do whatever it takes to help you find your WHY. From a one-man-show in 2020 when I started, to now having a stellar staff with Tiff and Zach that share the same energy, this team has a wealth of knowledge and share it freely so you can be your best and feel your best. The small group classes give you the personalization that you will not find at the big-name brand gyms. The Impact coaches genuinely care about you and get to know you on a personal level, which makes it easier to keep coming back :) I cannot imagine going anywhere else but Impact!

I was once a swimmer and runner, occasionally hit the gym (without really knowing what I was doing), ate well enough (so I thought), and stayed fairly thin throughout most of my 40s. Then the pandemic hit, family obligations became more of a focus, and I crossed the line into my 50s. I had put on 25 pounds in a few short years and found it difficult to motivate. Feeling sorry for oneself without the motivation to facilitate change was not a happy place to be.

In August 2023 I tore myself from the couch and visited Impact, not really knowing what to expect. I met Coach Peter and felt encouraged by his enthusiasm and understanding. But what really sold me was finding a community of like-minded folks from all walks of life, people who I've come to regard as kindred spirits. Coach Peter introduced me to the other coaches, Tiff and Zach, all three of whom have since turned my life on its head.

It's been 7 months since I started. At 53 I've never felt better, never looked better. I've become obsessed with improving my strength, endurance, and general well-being through proper form, nutrition, breath, mindfulness - all thanks to Coaches Peter, Tiff, and Zach. Ongoing assessments, workshops, motivating emails and texts, the encouragement of others in the Impact community... I could not have asked for more.

I have absolutely no hesitation recommending Impact. An easy 5 stars.

I started attending Impact about 9 months ago after my wife sent me a link to check out this local gym with great reviews. After a few classes I was hooked and have been going ever since. The coaches are great and will tailor the workout to any fitness level.

I was suffering with a muscular issue with my shoulder for about 6 months before joining. I had tried stretching, the chiropractor and exercising on my own but nothing helped. After about of month with Impact I was feeling real improvements and now it’s basically a non issue.

The coaches are great! They have genuine interest in your success and helping you stick to your fitness goals as well as goals concerning nutrition and mental health. Would highly recommend giving Impact a try!

I started going to Impact MW about 3 years ago and started when I was 14. At first, I was super iffy on working out in groups because I hated working out in front of people, until I started coming here. Although I am one of the youngest people that train here, I love love waking up to go to early morning sessions and seeing the “morning crew.” I also like that this is a gym where you’re friends with everyone and can joke around through a workout unlike other gyms where you always feel like you’re in someone’s way. %1000 a non-judgmental gym. Coach Tiff, Peter and Zach definitely hold you accountable and make sure you’re coming in.

I am a fitness instructor myself, but was feeling like I needed a little something extra in my own fitness journey about 8 months ago. I found Impact through a google search and was intrigued by the small group personal training format and decided to give it a try. From the moment I first contacted the gym, Peter was incredibly attentive and made sure to understand my "why" so that he could best support me in my fitness journey. Classes are certainly difficult, but not so hard as to leave you feeling defeated which I appreciate. Peter & his team are willing to put as much effort and time into your journey as you are! I am now 20 weeks pregnant, and I couldn't be more grateful for Impact throughout this process. It has made me stronger and leaner (until I got pregnant) and now has left me feeling strong, capable and MOBILE over the last 20 weeks. I can't stop saying how great I've felt so far throughout this first half of my pregnancy and I attribute a good amount of that to the type of work we do at Impact. The modifications allow me to continue to get a great workout but take into account that changes my body is going through and I value how much Peter & his team are able to adjust the workouts to fit whatever you are dealing with in life. Can't wait to continue exercising through the next 20 weeks and then to build my strength back up post baby!

Joining Impact Metrowest was one of my best life decisions in 2022 - a true investment in my wellbeing journey. Coming off of PT rehab for a frozen shoulder, I was scared of resuming workoutss for fear of re-injury. Plus, I had been worried about maintaining my weight (having lost 30lbs the 18 months prior.) Unlike other gyms, Impact's focus is on functional strength - not aesthetics - which is way way more important to living well. Coach Peter - and now Coach Tiff as well - have made me stronger and resilient. 4 chief reasons why i'm happy: 1. I love the small group class format as it means your form gets checked frequently and adjustments made as needed. 2. The frequency and times of classes work with my schedule 3. The format and variety of our workouts keeps it challenging and entertaining. 4. Coach Peter & Coach Tiff's personalities! I highly recommend for anyone looking to recalibrate and fuel their journey to health and fitness.

Today marks two months that both my husband and I started working with Coach Peter at Impact.

We were looking for a change in our physical and mental well-being, we had let the life of working parents get the better of us and we were not making time for our own wellness.

These two months have been transformative for us on so many fronts. Coach Peter has led us to a combined 30lb weight loss, improved cholesterol and A1C numbers, confidence, closeness in our marriage, more vibrant relationships with our kids and overall well-being.

Not only have we benefited but we have also benefited professionally - we are sharper, more confident and nimble.

This is only the beginning of our journey but the marked improvements for our whole family on so many fronts are more than we could have ever hoped for.

I have been to many trainers/gyms in my life and have a very good understanding of what makes a good one. Peter is one of the best. I regularly run long distance obstacle course races (including 12-hr and 24hr races). I've done ultra-trail runs of 50 and 60 miles. I know exactly what is needed to be in tip-top shape and Peter consistently helps me be in that tip-top shape. He is also more than a trainer - he provides valuable exercise, nutrition, and betterment. If you want your body to be the best it can be, then you should be going to IMPACT. It's that simple.

Peter is knowledgeable, attentive, energetic, and truly cares about his clients. I shopped around with several other trainers and no one comes close to his level.

You really can’t ask for anything more from a strength trainer. His focus on body alignment is well worth the extra effort— I came into impact because I pulled my hip muscle from playing fetch with my dog. I was becoming afraid to do any dynamic physical movements and felt weak. After just one session with Peter, I sprinted alongside my dog down a field to race him to the ball.

I felt like an invincible well oiled machine.

In class Peter is full of energy and is highly motivating. He often checks on everyone’s form, which is something I’m grateful for. I am looking forward to getting into the best shape of my life with Peter’s help. Can’t wait to see more results!

I decided to step up my health and fitness journey three months ago when I decided to look for a personal trainer. But oh where to begin!! I came across Impact Fitness and Coach Peter with his five star reviews. Instantly upon meeting Peter, I knew this was where I belonged! Peter takes his time getting to know his individual clients needs, creating personalized workouts to improve muscular endurance, flexibility and cardiovascular health in small group settings. He also sets fitness goals and monitors his clients progress, which includes the importance of healthy nutrition and sleep. Peter not only is truly invested in his clients becoming their best version of themselves, he also has the perfect personality for the job! He makes workouts fun (never boring!) and attainable for all fitness levels. Peters knowledge is spot-on, he always has words of encouragement with every class, and genuinely is as excited as clients are when we reach new fitness milestones. I’m three months in, twenty pounds lighter and haven’t felt this healthy since my twenties!! So do yourself a favor……run, don’t walk if you’d like to be your healthiest version of yourself and go meet Coach Peter!

Coach Peter is the best hands down!

I was having this annoying tingling feeling in both hands and trust me it’s the most annoying feeling ever. When I first met with coach Peter he was very clear in communicating what we would be working on and how we will get to the goal I wanted. I really appreciate the level of interest and care that he had in seeing me get better. He takes his time with you even though there are other folks in his sessions, you never felt left out and he was keen on ensuring am I doing the right things and not overexerting myself to make things worst.

I started going to coach Peter to help strengthen my back which along with help from my Chiropractor started to work in no time. Not only did the tingling go away, I also started to feel stronger, healthier and was seeing great results in how my body looked. Coach Peter really knows what he is doing and makes his sessions fun and very active, you feel so accomplished after doing the daily/weekly 1 hr workout.

If you need someone who will be there with you every step of the way on your fitness journey to a stronger and healthier lifestyle then coach Peter is the person, he truly cares. Coach Peter you are the man sir! Thank you for all that you do and all you have done. Much respect!

Coach Peter is amazing! He is extremely knowledgeable and highly motivating. His enthusiasm knows no bounds. He can work with anyone regardless of age, body type, or any physical limitations. I have been a client for many years and can personally attest to the value he brings to the table. He has shown me many different ways to be as flexible and mobile as I can possibly be. He will work with you if your schedule makes it difficult to get into the gym. If you are looking to be in the best shape you possibly can be, the wisest thing you can do is to call Peter!

Peter is a fantastic trainer and motivator! He prides safe foundational exercise movements and helping people be their best. I've personally worked with Peter for knee rehab and was impressed with how detail oriented he is. His caring and supportive nature makes us confident in referring him to our patients. He also works hard to educate his clients, not just take them through the motions. We've even had Peter host a workshop for our patients to share his knowledge of pelvic drop and its impact on biomechanics and quality of movement. Pick Impact Metrowest if you really want a positive impact in your life!

I've been training at Impact with Peter and Duncan for 2 years. They are knowledgeable and extremely motivating! The group training sessions are small and allow for an intense full body workout with supervision. Its like having a personal training session. Training at Impact has allowed me to stay active and pain free. I'm a believer!

Thin is not necessarily well. I learned that the hard way. I have been obese and suffered from back pain for most of my life. After losing over 100 pounds, I realized that I had also lost a lot of muscle. I could no longer lift a 50# bag of dog food and tired easily. I ran the Boston Marathon in 2016 after spending thousands of dollars on physical therapy to get me to the finish line. I came to Peter to help me run faster. I got SO much more! Coach Peter and Duncan have worked to keep my body aligned,and to stretch, strengthen and stabilize. I just feel stronger, my posture has improved and my lower back is almost 100% pain free. You can't put a price on that. I ran Boston again last year, slower and stronger than ever. Every day movements are easier and that is what is important. I would rather grow old and be able to lift that bag of dog food than to run faster in a marathon. I am eternally grateful for having Coach Peter and Coach Duncan in my life. The health benefits far outweigh the cost. I can't put a price tag on living a pain-free life!

Coach Peter at Impact Metro West is amazing! Due to a back injury, I went from working out six-seven days a week to no days a week. When I finally felt good enough to get back to the gym, Peter eased me into working out again and taught me what I needed to know so as to not injure myself again.

He’s extremely knowledgeable in what he does but his dedication and commitment to his clients is what distinguishes him from other trainers. Each week when meeting with Peter he’s done a significant amount of research on my problem and constantly keeps up on his research to get me better! Thanks Peter for helping me get my strong back and truly making an impact!

As a massage therapist and yoga teacher, I have seen a lot of people injured by crazy workouts and inappropriate coaching, so I was a bit cautious when I first started working out with Peter. However, after working with him for over a year, I can say first hand how the RIGHT coaching can make a huge difference in helping your body and muscles function correctly and protect you from injury. In addition to being a top coach who knows his anatomy better than anyone I know, Peter has an enthusiasm that is contagious, a passion for life that is inspiring, and a depth of knowledge that has helped me in my own life, and in my work with others.

There are lots of personal trainers out there, but Peter is the most knowledgeable trainer I've ever worked with. He has a doctor-like level of knowledge of how the body is supposed to perform and if a single joint is out of alignment, he works with you to stretch and strengthen the muscles needed to get that joint working properly and improve fitness and athletic performance. He's the real deal. I'm a runner and had been having lots of injuries to my knees, hips and feet that would take me out of action for a while. I've been working with him for over a year now and haven't had any problems like I used to because he's working at correcting my movement, strengthening the muscles that need it and making my overactive muscles more flexible. Can't say enough good things.

Peter McMahon is a true professional, an amazing resource on fitness, and a selfless and giving person. I have been lucky enough to train with Peter for over a year, and in that time he has helped me overcome physical and mental obstacles that stopped me from getting the best results out of my fitness regime. He works tirelessly (seriously does he ever leave the gym??!!) to make sure the people he coaches are set up for the best possible chance of success, whether that be through workout routines, diet advice/meal plans, and positive reinforcement of general life strategies to get the best out of yourself. If you have been struggling to get fit or think that doing so is impossible, I highly encourage you to see Peter so he can change not only your body, but your mind as well!

Peter is the best at what he does. He knows the body in and out and will help you figure out your weaknesses and improve on them. I started with Peter in April 2016 after having knee surgery in January 2016 and he put me on a corrective exercise program to strengthen my knee as well as improve my shoulder immobility which has been a problem for me since 2004. It's hard to find a coach that is as passionate as Peter. If you're looking for a tailored program to your needs and goals, this is it!

Peter's enthusiasm is contagious and his knowledge of fitness is top notch. I’ve dropped two clothing sizes, maintained my weight loss and more importantly I feel better. Peter does an initial assessment and then he customizes your program to meet your needs and desires. I’m a seasoned mom and for years I’ve battled back issues. He has helped strengthen my core, increase mobility and stability. This is HUGE for me as for years I’ve spent days sitting on the coach when my back went out. Those days are gone. I can move efficiently and if for some reason I get off balance I’m able to react quickly and not get hurt. This allows me to continue hiking and enjoying nature with my family. My family and I hiked 8 mountains this summer, some with some pretty steep rock climbing areas where you needed upper body strength, focus, and confidence to meet the challenge. After a year with Peter, I did it with ease and enjoyed some amazing views and made memories of a lifetime! I look forward to breaking more barriers down physically and mentally. So if you are looking for a fitness coach that will not only get you in top physical & mental shape at any age I recommend Peter McMahon of Impact MetroWest.

Peter is the most enthusiastic and passionate coach I have seen. His commitment to health and performance is contagious. From a detailed screening, to personal diet blueprint and specific exercises, his coaching is absolutely personal and educational. He not only helps me get stronger, but also resolved a knee issue that has been lingering for the past 3 years. He coaches me to "bullet-proof" myself through exercises, physically and mentally. Now I am more excited to train harder and perform better in my upcoming races

i joined Impact Metrowest Personal Group Training this past January 2016. I'm already a very active person II belong to a gym where I run and do a bunch of Cardio. However I was interested in adding strength training ,corrective training, and some guided workouts and nutrition. I'm down 10lbs and my body fat has dropped.Monthly assesments to keep track of my progress..all my intial measurements have gone down in size. People have commented that I look more fit. If you want to look and feel better Impact is the way to go. Motivating, Educational Coaching with a very positive atmosphere. The proof is the mirror I look and feel better its been an IMPACT !
