The variety and intensity makes our time interesting and effective. We work on core, strength, coordination and cognitive exercises. I am close to 70 years old, yet I am able to play full court basketball 4-5 days a week in large part due to Moe’s training methods. I highly recommend Moe as a trainer for clients of any age.”

I never came away with any discomfort, just a solid feeling of having worked out and increased mobility. Lauren is great!!!”

- Anna., client 

“I had always been hesitant to invest in a personal trainer... it seemed like a frivolous luxury since, as an MD, I should know what to do, and besides, I used the elliptical and walked regularly. But I was getting bored and needed new input, especially on managing arthritis and other “aging” issues. After my first assessment visit with Rebecca, I felt like she really listened and observed, and understood my goal for general health maintenance and control, general sense of well-being, and ability to independently make corrections when something starts to hurt. I’ve been out of the country for a month now and can’t wait to get back into our routine...I always feel great and stand taller after our sessions!”

- R.E. Hanson, MD, client
