I am a 67 year young woman who was recouping from a broken ankle. I found David and decided to give him a try rather than going back to the gym....boy am I happy I did - David is very professional, listened to me and then worked with me to strengthen my ankle and also my balance (in hopes that I won't fall again). David is wonderful - I so look forward to my time exercising under his guidance. He has worked with my age, limitations and time constraints ( I travel a lot) - next trip I will be gone for 6 weeks and he has offered to send me a link so I can have it accessible to me and hopefully have the time to do it (or some of it) while I am away. Not sure if I will ever go back to the gym again - David has been a terrific teacher and motivator with great patience. He and his company are the best in the business - highly recommend them.
