Mark is an excellent trainer. Being in my 40's and working from home, I found myself with a lifestyle that was mostly sedentary. Even though I bought weights during the pandemic, i never found myself using them or gravitating towards resistance training - and the long and short of it was because I never really learned how to do it properly.

I've been with mark for about a year now, and I've noticed significant improvements in my health, mental clarity, and looks - I know the next step is on me to take care of my food/drink intake, but I never thought I'd say that I genuinely look forward to working out with mark at the end of a long day - several times a week.

Mark is also data oriented, and keeps track of progress. He adjusts each workout to make sure you maximize everywhere you can. His approach is thoughtful, and on top of that - he's genuinely a great guy.

Highly, highly recommend - and contact me if you need any other information!

Mark is a gem! I've been training with him since I was 8mo post-partum and the impact has been both immediate and life-changing. I came to him with recurring pain from re-injuring my back and he got me dialed in with the perfect exercises to quickly ease the pain and got me on a weight training regimen that built strength that prevented my back from going out again. Over time Mark taught me to build strength with a lot of patience and gentleness. I can't recommend him enough, Mark's training sessions have been the best investment I've made for both feeling great in my body every day and for protecting myself from future aches and pains. Mark is also just a delightful human being and a real joy to be around. You can't go wrong, just book him.

I’ve been training with Mark for over a year, and I can confidently say he’s the best trainer I’ve ever worked with. At 60 years old, I’ve worked out off and on throughout my life, but was struggling to stay consistent with a demanding work schedule and the realities of an aging body. Mark has been incredible at tailoring my workouts—always challenging, but never overwhelming—so that I stay motivated and continue to make real progress.

What really sets Mark apart is his personal example. His achievements in endurance sports—from 500-mile bike races to running rim-to-rim-to-rim across the Grand Canyon (twice!)—are incredibly inspiring, yet he’s extremely humble and approachable. No matter your fitness level or age, Mark has the skill and intuition to develop a plan that helps you meet your goals. I highly recommend him to anyone looking for a supportive, knowledgeable, and truly inspiring trainer.

If you are into running but want to get better at running by incorporating strength training and you are in the Bay Area, look no further. Mark Kolding is who you want. I was a complete novice when it came to strength work and had never been to a gym. Mark was so patient with me but adequately pushing me to get better with each session. Over a period of time, it got better progressively and I have seen my running improve in terms of speed and recovery after each run. Mark is very organized with making note of all the work we have done in each session so he can appropriately change the workouts or make them more challenging with each session. Thank you Mark for the support you have provided in the last few months!

I found Mark when looking for a personal trainer who had experience in endurance sports. Mark’s background in running, triathlon and ultra biking gives him unique insight when working with athletes competing in endurance sports. I highly recommend Mark if you are looking for a personal trainer to help get you to the next level in your sport.

I had shoulder problems and was introduced to Mark by my PT. Mark and I started weekly training 4 months ago and my shoulder has improved. Surgeon says no to surgery! Mark had me strengthen the shoulder with care - which worked. He also coached a healthier lifestyle regarding food, alcohol and exercise. His coaching is aimed at creating healthier habits, not quick fixes. He is an expert trainer and a good human being. Highly recommended!

Mark is a great trainer. I worked with him for two months during which he taught me about good form and started me on my workout journey. He is a great writer too! His blog “high protein per calorie” motivated me to change my diet and achieve my goal of loosing 20lbs.

Mark Kolding is both a great trainer and person. Every workout is unique to me and he manages to make them fun! I originally sought out Mark’s services to help me keep a New Year’s fitness resolution and it has now turned into him training me for my wedding this year! If you’re looking to work with a smart man who practices what he peaches, Mark is your guy. I have full confidence in saying he’s the best trainer in the east bay!

I have been working out with Mark for almost 2 years. I have spine issues and he is very good at tailoring my workouts to my individual needs and goals. He varies each workout and strikes the right balance to continually challenge and motivate me. He is a pleasure to work with and I always leave feeling so much more productive and accomplished than I would if I were on my own.

By the time I retired from a fun-filled career, my weight had ballooned to 292 lbs and I felt terrible. I was without a doubt, in the worst shape my life. After seeing some of my co-workers who suffered from strokes and heart attacks, I decided that it was time to do something about my weight and overall health. I've had a lifelong goal to ride my bicycle from San Francisco to New York city. Now that I'm retired, I have the time to do it without any time constraints. I knew I needed to do something to get in shape for this ride. I started looking around and I saw an ad on Craigslist for a personal trainer, Mark Kolding. One of the things I noticed, was in his own personal description. He's a competative triathlete and has completed cross-country bicycle rides in the past. He even competed in the Silver State 508, a non-stop 508 mile race across the Nevada desert. A race that is arguably the toughest in the world. I got a hold of Mark and started working with him in January of 2023. Within 7 months, I'm now down 55 lbs., about halfway to my goal weight. I feel so much better overall. My blood pressure and pulse are down, and my back feels much better.

One of the things that I've been so impressed with Mark is that he speaks from experience. Not only is he highly educated with a Master's Degree in Exercise Physiology, he lives the lifestyle he teaches. Mark has an incredible eye when it comes to training. He knows just how far to push somebody without going too far. He is completely attentive to his clients and devotes 110% of his focus on them during their sessions. You will never find him distracted or diverting his attention to his cell phone, other than to help and provide pertinent information. Mark has also been an invaluable resource for my diet, which he routinely keeps track of. Mark is very accommodating and flexible when it comes to scheduling. Give him a try, you won't regret it!

My husband and I have been working out with Mark for a couple of months now. Before we started with Mark, we were not motivated and dreaded working out in general. Mark understands your fitness goals and current strength before he starts you on your journey. He is consistent and also pushes you to do your best. I am already feeling stronger and looking forward to continuing working out with him.

Mark has quickly become a focal point in my health turnaround. Facing a knee and hip replacement (and way overweight) I have greatly improved my health and quality of life. My fitness level increases weekly, as does my weight loss journey. He is transparent and assuring in his methods, laying the groundwork for measured and gradual improvements. Having never used a personal trainer before, I would highly recommend Mark to anyone considering a personal transformation.

Mark is an amazing trainer. Over the past 9 months we have worked together to both build up strength and lean out. I first approached Mark in September of 2022, and had been in an intensive intermittent fasting cycle. So much so that I was barely eating anything, yet unable to lose any weight. Mark immediately came up with a plan of action and suggested I increase my intake and begin weight training with him. Over these past months I have gained incredible amounts of strength - I have lifted PRs in benchpress, squats, and deadlifts to name a few. When I have a workout session with Mark I always sleep like a baby, and truly enjoy the work we put in together. It also helps that Mark is just a fun guy, and someone that is easy to connect with. If you are looking for a trainer who can get you to your goals, while having fun doing so - Mark is your man.

Mark - has been outstanding in helping me build muscle strength and confidence. I feel very good about the progress that I have made in such a short period. He also offers great nutrition advice. Great coach and very positive.

Mark is a top notch trainer. His background not only as an ultra endurance athlete, but with his extensive education in exercise science and nutrition noticeably inform his approach when working from client from client. My mom and I often see him together, and his ability to modify and tailor the same workout plan to us both at the same time shows the attention to detail he puts into each of his clients. He is constantly listening and adapting the workouts to my strength goals, all the while pushing me out of my comfort zone.

I've worked with trainers in the city at twice the price, he gives them a run for their money. He is a wonderful person, free of judgement and preaches a realistic and healthy approach to achieving your fitness goals. It's always a fun and challenging day at the gym. I couldn't recommend him enough, he's the best.

When I started working with Mark, I was returning from a year long break from work outs as I was recovering from a surgery. I could barely do simple core exercises without getting cramps in my stomach. I have worked with Mark for only two months now and am already seeing a huge difference in my level of strength.
I feel a higher sense of confidence in my ability to lift weights and a sense of strength through the day that I have not felt in a while. Mark took the time to understand my areas of weakness and created a plan to systematically grow my strength in those muscle groups. We take measurements after a certain number of sessions, and my most exciting moments have been seeing a progression of increase in my muscle mass and decrease in my body fat - exactly what I wanted to see on the scale!!
With Mark, you can be confident your health is in safe hands.

I've been using Mark for the past year and couldn't be happier. Mark is great at setting up fitness goals and ensuring that the full picture is complete. From identifying focus areas, to helping establish weekly plans for endurance training to nutrition. Highly Recommended if you are invested in whole body health and fitness.

I cannot recommend Mark highly enough. He is amazing!

Earlier this year I got to about 50 (maybe 60) pounds overweight. I have been gaining weight fairly consistently (3, 4, 5 pounds a year?) since I was in my early 30s. I was approaching 300 pounds and knew I had to do something about it. I figured I could just eat less, exercise more, and lose weight (as has been my plan before). Well… it didn't happen (as was the case before).

I called Mark and we discussed my situation. He put together an exercise plan and a diet plan for me and he put me on his schedule for three days a week at 6am. The exercise and diet plans were challenging, but not unreasonable. I worked hard and watched what I ate, but it was never too hard and I never watched too closely. And, Mark held me accountable by being supportive of my efforts and keeping me enthusiastic about leading an active, healthy lifestyle.

Long story short, I lost about 30 pounds over the course of about 3 months. I’m in better physical shape (improved strength, flexibility, and endurance), have better eating habits (eating more good/less bad stuff, more aware of when/why I am eating, doing regular intermittent fasting), and I am on a path moving forward to maintain the gains I made and minimize the setbacks that are sure to come. I have moved on to working out on my own and I am trying to turn Mark’s help, guidance, and training into a sustainable (and sustained) lifestyle change - which has been a great success thus far.

All that said, I have Mark’s phone number close at hand, just in case…

We’ve been working out with Mark ever since Crunch closed in 2021. He changes the workout every week increasing in difficulty without us even realizing it. He is fun to work out with and adjusts for any physical limitations while also tailoring our workout to help overcome those limitations. Strength training and balance are always part of the session too. You can’t forget the those fitness and lifestyle emails with reminders about healthy eating tips and apps to track progress on your goals. I would highly recommend if you’re looking for a good workout and overall fitness regime

I highly recommend Mark as a personal trainer. Since I was new to personal training, and in my 50’s, I was wary at first, but Mark has earned my trust and respect by demonstrating his expertise in exercise science, body mechanics, and nutrition.

Mark has been instrumental in my fitness, weight loss, and nutrition journey over the past year. He patiently listens to my goals and challenges and helps me implement specific changes to improve my eating, activity, and general well-being.

Mark makes weightlifting and working out fun (something I did not think was possible), and ATP Fitness is a gem of a gym. Mark encourages me to push myself in a non-judgmental way. I’ve gotten stronger and leaner under Mark’s guidance, have tons more energy, and I look forward to working out with him.

Mark knows I’m interested in learning more about the science behind what we are working on together and he sends me relevant articles, videos, and writes blog posts to educate and inspire. I have learned so much from Mark and I appreciate how he has customized and adjusted specific plans for me to reach my short and long term goals.

Plus, he’s a super nice and likable guy, which is important when you’re spending three hours together every week! I feel lucky to have found Mark and if you get the chance to work with him, don’t pass it up!

I have been working with Mark for over a year now and I have learned so much about fitness because of him. I started as a weak small teenage kid hoping to get in the gym to get stronger and more athletic. After the first couple sessions I knew he was the proper trainer for me. He went at my pace and gave me encouragement which helped me strive to be my best. A few months later, I felt like a new person. I gained 15 pounds of muscle, I felt more coordinated, and my body had never felt better. I owe my fitness accomplishments to Mark and his effective training.

Mark has such a unique background, his experience as an ultra athlete really helps ground me. I have had a lot of false starts on getting and staying fit. Mark has not only helped me lose weight, but I feel great and am the strongest I’ve ever been. Safe to say I am also tremendously happy. Mark helps me debug all of my nutrition missteps and is thoughtful in making sure I appreciate the progress I am making. I’d highly recommend him to anyone looking for a trainer!

I have been training with Mark for a year. I am in my 60's and realized my need for accountability in the area of developing better eating strategies and a strength training program.
Mark develops twice weekly for me a safe program that works on helping me enhance my balance, core, cardio, and overall strength training. Over time I have gained new confidence as I have met and increased my training goals, toned, and my overall body composition has changed while I feel stronger and more fit. Due to my age and limitations, I present a few challenges however Mark goes the extra mile in reading blogs and articles to find the best exercises to strengthen those areas that are stiff and painful such a hamstring stretching and shoulder exercises.
Mark is non-judgmental, motivational, inspirational, professional, and insightful in his knowledge, and wisdom, while providing positive encouragement towards a healthier lifestyle.
Mark offers to plan a workout program for my days at home as well as a program when I am away on vacation. Mark is committed to helping me stay focused to attain my goals and focus on the positives of learning to live a healthy lifestyle while making healthy lifestyle choices.
Mark writes and send weekly motivational articles on topics related to health and the fitness world which I find helpful and informative.
The gym is welcoming, pleasant, and provides a pleasant work out experience. I encourage you to meet with Mark and develop a goal setting plan to a healthier life!

Mark has been one of the most impactful personal trainers I have had - I have worked with him for the last one year and in a relatively short time he has helped me boost my confidence around my health as I have exceeded my strength goals. I feel so much stronger and healthier directly as a result of my work with him. He took a lot of care and attention to ensure that the training program was tailored to my specific goals and needs. He diligently worked around my weak spots and systematically helped me build strength in those areas.
I found him to be flexible, empathetic and with an intuitive understanding of when to push VS let go. He is very knowledgeable and well read in both the health and nutrition space and makes it a point to incorporate the latest and best practices in our workout. Besides reading his informative weekly blogs, I enjoy discussing with him why one technique is more effective than another and learning about how minor details during the workout can make a big difference on the outcome.
I highly recommend Mark and sincerely hope you get a chance to work with him!!

Mark is a great guy personally and professionally. We've been working together for 16 months now.

I came here because I wanted to build muscle and get in shape. I knew I needed a higher caliber personal trainer then at traditional gyms.

I’ve been getting much stronger, my productivity at work has increased with my new energy and overall I feel better and happier all day long.

Mark has a unique skill set in that he is able to identify the amount of food you need right off the bat, and you get an actual color diet plan document. Mark helps me prioritize certain exercises over others, which is extremely valuable to me as I can get the most out of my exercise time. As an example, I'm shown how to safely perform exercises that help build strength and provide a stretch at the same time.

Mark is always very well spoken, on time, very positive, and helps hold me accountable in our interactions. Mark constantly looks to provide additional value, even when things are, in fact, going well. I never feel like I had an experience that wasn't valuable with Mark. If you get a chance to work with Mark for your fitness goals, consider yourself a lucky person. I can't make a higher recommendation.
