Soooo... 60 plus crowd. We started on a Amazon Local deal. Absolutely amazing! We can't do all of the exercises the way the veterans do but we get by and we get encouraged. As foolish as it sounds and is we go at 5 am. Thad [instructor] is absolutely as patient and understanding and he understands that it just don't work the way it used too. Range of motion improving rapidly, can finally do a full squat, almost do pull up, but best of all he understands and helps.
