Susan set a realistic timeline based on my injury, and I am pleased to say we blew away my expectations in three months.”

“Several months ago after hip replacement surgery, it became apparent that I would also need a knee replacement. So, I joined the JCC to work with a professional trainer in the hope that the discipline would encourage me to work on building the strength back.

“As a senior, I’m used to being patronized by young, fit individuals and Taylor did none of that — he was encouraging, respectful and tough and always helpful in teaching me correct positions, which enabled me to do much more work without jeopardizing my knees and/or my hip. I was also able to work more successfully at home with resistance bands after his instruction on proper form. My strength quickly returned, which encouraged me to continue the training right up to the week prior to surgery. I am confident that my recovery process will be improved by the work we put in, and I look forward to returning after the post-surgery physical therapy. Most importantly,

Taylor made the sessions fun by changing up equipment and making other training “toys” available for our sessions together. I recommend the JCC and Taylor to anyone and everyone I know. Bravo!”

- 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!”
