Outstanding Trainer and Partner in Health & Fitness ->

I highly recommend Sam and Chain Reaction Performance.

Sam is knowledgeable—not just in fitness training, but also in nutrition, overall health, and even the mental side of wellness. He designs a program that’s sustainable, enjoyable, and that delivers results.

My personal goals are focused on building muscle strength to stay ahead of aging and developing better nutritional habits to support that. Sam has been a true partner—keeping me accountable, challenging me in the right ways, and always keeping workouts fresh and engaging.

I value his customized, dedicated approach which is tailored to my goals and lifestyle. I trust him with my health and fitness, and I’m already seeing results that feel sustainable long-term (yay!) - so grateful to have Sam for this guidance.

If you’re considering working with a professional trainer, I can’t say enough great things about Sam.

I've been fortunate to work with Sam for nearly 6 months, and in that time, I've both lost weight and gained an amazing amount of strength. I wasn't sure what to expect from working with a trainer, but I now think it's very worth it, especially with Sam! Sam's expert guidance and accountability, for both fitness and nutrition, have helped me be the strongest I've ever been in a very short time. He takes time to understand your goals, and he gives in-the-moment coaching on form to prevent injury and ensure optimal results. He's highly professional, thoughtful, and interested in your long-term, sustainable success. I highly recommend his help!

I first began training with Sam 3 months ago. I came in with shoulder and knee injury and I was terribly out of shape. I had no idea what I was capable of doing until he began training me. My shoulder and knee are so much stronger now! Training with Sam has given me confidence to push harder and push myself to a level I have never been!
Sam is professional and always gives his best each and every session!

I've had the pleasure of working with Sam for several months and cannot recommend him enough! I came to him because of ongoing back issues that were preventing me from continuing my fitness journey. From the very first session, I could tell that Sam was knowledgeable, experienced, and dedicated to helping me solve my back issues achieve my fitness goals.

His workouts were challenging but always customized to my fitness level and personal goals. He pushed me to work harder than I ever thought I could, but also knew when to adjust exercises to prevent injury or overexertion.

Sam was always punctual, professional, and enthusiastic about helping me reach my goals. He was also extremely approachable and always available to answer any questions or concerns I had outside of our training sessions.

Thanks to Sam, I have achieved significant progress towards my fitness goals, my back feels better and stronger, and I am more confident than ever before. I cannot recommend Sam enough to anyone looking for a knowledgeable, motivating, and dedicated personal trainer.

Sam Weinberg is a phenomenal trainer. He takes a genuine interest in the goals you're trying to accomplish and creates a workout plan tailored to those goals. For me, I was trying to gain weight and build muscle. I tried accomplishing this on my own on and off for 15 years with no success. Within 6 months of working with Sam, I gained 25 lbs with a noticeable difference in my arms, chest, and legs. Whatever your fitness goals are, I highly recommend giving Sam a call.

I recommend Sam as a personal trainer without hesitation. He is an experienced, well educated and motivated trainer. Sam will custom tailor a program to meet your individual goals. I’ve been working with him for less than a handful of months, and the results he has helped me achieve have already passed my initial goals. You can believe him when he tells you he can help.

Our son was looking to build muscle for hockey. He had done strength training before with his team, but had not built the muscle he wanted, and was getting injured. He spent the first 2 weeks with Sam learning form and how to train the right way. We love Sam’s wholistic approach: training to build strength and prevent injury. He talked with our son about nutrition and hydration (he always hears that message from Sam better than his parents!) He was eager to train with Sam daily, and made it a priority. This is a tribute to Sam and his investment in his athletes. Not only did our son reach his goals, he is dedicated to continue the progress he made with Sam. They stay in touch even though he has moved away from Colorado; Sam guiding him along the way. Sam builds great relationships with his athletes, and truly wants to them succeed. Thank you Sam for your investment and dedication to our son. He reminds us on a daily basis that what Sam says is pure gold.

Sam is a wonderful trainer. I have been weight lifting for about 15 years now but he is always helping me tweak my form to get the most out of my exercises. I have gained a lot of muscle in weak areas that I did not realize were weak. Sam has helped me with knee pain and lower back pain through building stronger muscles to take stress off these areas. His dog Sarge is also a joy and always puts a smile on my face. I highly recommend Sam, I would never go to another trainer after working with him. Thank you Sam!

I began training with Sam my freshman year of high school with the goal of gaining weight and getting stronger for baseball. Sam trained me five days a week and helped me to restructure my diet so that I get could get the most out of my work in the weight room. By the end of my freshman year, I had gained 30 pounds, going from 130 pounds to 160 pounds. Not only was I stronger, but I was also more confident in how I looked.

I have known Sam for several years and just recently started training with him in August. I have already seen major changes (2 months so far) in my physical fitness, mental health, and have crushed a lot of my personal goals I set with Sam. He is very knowledgeable about fitness and nutrition and has been training me to do exactly what I asked him for. I feel lucky to have the opportunity to learn from him!

Sam knows his stuff, pushes you hard but not beyond safe limits. In addition to his expertise on body movement and strength, he is also very knowledgeable on nutrition and body recovery. I've trained with Sam for 3 years now and couldn't imagine training with anyone else. I would recommend him to anyone for any level!

I have worked with Sam Weinberg for about 4 years. This is what you get with Sam. A man that deeply understands how the body works and how to help you achieve your goals whether it is to get stronger, more fit or to keep you injury- free to help you perform at your best. He knows that each of us are different and one program does not fit all.

Sam will work with your exercise, your diet, your rest, your cardiovascular systems and your strength. He knows that all are critical to your success.

If you are a young athlete or coach a team, call Sam. If you are a middle aged man or woman that wants to get in shape for ski season, call Sam. If you want to perform at your best, call Sam.

I have been very impressed by Sam. He has helped my 9th grade son gain flexibility, strength and speed. He has extensive knowledge of exercise physiology and kinesiology. He is patient, funny and a great motivator. I am pleased with his focus/emphasis on the correct form and set-up for each exercise to maximize benefit and reduce risk of injury. He has a baseball background and is able to communicate effectively how different exercises are beneficial to baseball players.
