I have been going for over a year. Started 5x a week---now about 3x a week.
I may be one of their failures in the loss department. May have lost an inch or two and no weight. I envy those whose lose so many inches.
HOWEVER, I love going and feel better. Originally when I started my shoulder was bothering me for over a year. Now, it is soooo much better. So really believe my other body parts are benefitting too.
