IMPACT PERFORMANCE TRAINING
Clients
Dewey,
I wanted to thank you so much for your time and energy in training for this upcoming fight. I have never been so confident in my physical conditioning. I feel incredibly strong and my cardio is the best it’s ever been. I have had professional trainers all my life but the gains I have seen while training with you are second to none. You have a unique ability to turn an athlete’s weakness into their strength. You have taught me that victory is earned in training. With that said, you will always be my strength and conditioning coach.
Thanks again,
Corey Sutton

Strength and conditioning training with Dewey Nielsen has brought my fitness level to an all time high. I owe a lot to him for my performance at the brazilian jiu-jitsu tournaments. I’m lucky to have a trainer as good as Dewey that actually knows about strength training and corrective exercise. I have become a much better athlete since I started training with Dewey and I feel that I can go as far as I want in the sport of MMA and Jiu-Jitsu because of my strength and conditioning program.

Dewey has taught me a vast wealth of knowledge about fitness over the past few years of training with him. He is an intelligent and innovative trainer. He is always staying up to date with the latest advancements in the industry. It is easy to see his care for the health and well being of his clients.

I would like to sincerely thank my strength and conditioning Coach Dewey Nielsen. I have been involved in athletics since the age of eight. I have competed at levels that range from little league to NCAA competition. Throughout my athletic career I feel that I have been blessed with coaches that have conditioned me to compete at my highest level. Without a doubt Dewey has put together an MMA specific regiment that supersedes any training that I have ever been involved in. Dewey’s ideas and practices are what I believe got me ready to win the FCFF light heavyweight title. I believe there is a perfect balance between strength and conditioning. Not only has Dewey been able to find this balance, but he understands how it differs in every individual he trains.
Respectfully,
Pro Escobedo
FCFF light heavyweight champion

I have been to gyms and worked out on the equipment. I have worked out with trainers from other gyms – but it is only since training with Dewey Nielsen that I realized and then surpassed my fitness and weight loss goals. Dewey made my time at the gym more efficient and effective and beyond that, gave me the additional information I needed to achieve success. The key was my willingness to learn from him and trust his advice. The result has been a loss of 40 lbs and being in the best condition of my life.

I have been training with Dewey for the last 3 years. I worked out before but never got the results I wanted, until Dewey showed me the secrets I was missing in the fitness equation. The man is incredible in the fitness lifestyle. I will continue to recommend him to my friends and family forever.

If you’re looking for a fad diet or quick-fix exercise program, Dewey is not the answer. What he IS, however, is someone who will realistically help you with your nutrition and training to guide you towards achieving your fitness goals. His program does not include pre-packaged food and lofty promises of quick results that inevitably end up being temporary as you deprive yourself of all the things you love to eat. Dewey showed me a common sense, healthy way to eat and live that I can use the REST OF MY LIFE while still enjoying real food. It’s not about deprivation. It’s about education and motivation. Dewey proved that with me.

Dewey is the kind of trainer who teaches and leads by example. He has a wonderful gift to relate well with individuals of all ages. He shares his tremendous body of knowledge about nutrition, health, and exercise in a calm relaxed, and confident manner. I was addicted to junk foods, had high blood pressure and cholesterol, and was about forty pounds overweight. Thank you Dewey, for teaching me how to eat and exercise properly.

Dewey's training has taken my over all conditioning to a new level. His training teaches you about how the body moves and what muscles are involved I learned what exercises I needed to correct my posture and achieve my goals. He builds a program specific to your needs ..sports, job, poor posture etc. This may sound like an infomercial but...I was 195 at 15 % body fat and now I am 185 at 10.5 % and feel great!

I’ve worked with Dewey for several years. He is a great trainer. He is very knowledgable about body structure, mechanics and his workouts are always challenging and fun. Dewey never stops LEARNING! We always refer patients to him for training.

I've worked with strength and conditioning coaches for high school, collegiate, Olympic and professional athletes throughout my career. More often than not, their instruction led the athletes into dysfunction and pain, rarely to improved performance. To achieve success with athletes, I encourage them to develop coordination as the basis for everything: flexibility, endurance, speed and strength. Dewey's knowledge and abilities are an indispensable asset in my ability to help an athlete achieve peak performance, and to plan for it to occur at a specific place and time.
