"Dennis literally starts from the ground up. Beginning his assessment of your body with the feet, making his way up the neck and jaw. With his deep understanding of the mechanics of the body, he consistently educates his clients on issues of alignment that affect the way we move."

"I have been training with Dennis Simpson since the Fall of 2004. He builds the body’s foundation and core and then builds on this work to strengthen other areas of the body. I have never met a trainer who knows so much about the human body.

When I started with Dennis, I was at my lowest point. He has the capacity to work with people who have had serious neck, shoulder, and hip injuries and to help them become strong, functional, lean people."

- Ronnit Palley

"I came to Dennis with so much back pain, and was in serious need of help. Now I’m back to running half marathons, my low back pain is minimal, my posture is great and my flexibility is maintained with less time stretching.

As I gradually began using the new orthotics, there was so much improved support that I didn't want to take them out."

"Dennis is adept at real time training design where he rapidly translates session goals into a challenging yet attainable 60 minute program. Fast, targeted and effective."

- Brian B NYC

"Since I started training with Dennis, I have improved my overall physical conditioning and cardiovascular endurance, have visible muscular definition and even my bad cholesterol went down and my good cholesterol went up, eliciting an audible “Wow“ from my doctor. "

"I have benefited enormously from training with Dennis. He is extremely smart. He knows the body and how it works and he customizes that knowledge to fit a client’s particular objectives, abilities and limitations. There is nothing stagnant or rote about Dennis’s training."

"I have been going to gyms and working out for 20 years and thought I knew all there was to know. Then I started working out with Dennis. He created an excellently organized, clear and simple weekly training plan for me that ensures that all the muscle groups in my body get a complete regular workout. Dennis challenges me continuously to achieve my maximum potential while being constantly attentive to preventing injury."

-Eric D NYC

"Being fun and encouraging, while maintaining a focused exercise program, Dennis has managed to keep me going to the gym consistently for over a year, which is no mean feat since i personally dislike exercise."

- LV

"I have witnessed dramatic differences in my levels of strength and endurance, working out with Dennis. Dennis has also taught me a great deal about working out without getting injured. He has a wealth of knowledge and shares it."

- Elizabeth S

"Since I started training with Dennis I have dropped three pant sizes in about three weeks (36-33 waist, my diet has dramatically changed with dennis help) and have begun to increase muscle size while losing body fat. What makes Dennis special is his voracious pursuit of health fitness knowledge."

- Christov P

"I injured my lower back when I was 19 yrs old and for 17 years kept re-injuring it. Dennis determined that my deep core muscles were not working properly and developed an exercise program to wake up those sleeping core muscles.

Today I am pain free and have the confidence to move the way the body was meant to move. Thanks Dennis, you are the best."
