My son does the Y class on his own and I sneak up and watch him for a few. He is really moving. It's amazing to me that this is working out so well. My son doesn't like to move or didn't like to move. He is getting about 3 days of exercise and my husband says that he doesn't complain about walking home anymore. My son asked if he could go to the Y thursday night when they have an outdoor adventure thing. I will try to arrange a ride for him.
