Nobody--NOBODY--is too young, too old, too fragile, too scarred, too small, too overweight, too pregnant, too ANYTHING to take control of his or her strength.
I've had cancer survivors in my gym. I've had patients of severe physical injuries in my gym. I've had people who have had no luck in physical therapy up and on their feet again because of training in my gym. When you have a trainer who knows what he's doing and truly has your best interests at heart, and when you truly want to achieve all the things you never knew you could, then no excuse is big enough to surmount your affliction. Not one.
