I'll admit i'm terrified of exercise but at just under 15 stone at 24 I need it, I eat well I just don't move unless I'm doing the school runs with my daughter. yet even that is a quick trudge up the hill home and back to the sofa. I have an old injury to my knee that plays up and I'm an asthmatic (due to my weight) so thats my keep handy excuses. My doctor says i'm all clear to exercise just take it easy at first. I just dont know how to go out and do it anymore, avoiding it im a pro but I cant do that any more. Any help or ideas guy/girls?
