What's A One-Legged Man Doing In A Gym?

I've wondered how amputees don't grow fat, I mean, how do they manage to keep fit since they can't do the fitness exercises that people with two good legs can. Anyway, this one-legged man has just proven to me that a person doesn't need two good legs to be fit or to be happy.

You are going to see him pull off an amazing ball trick, and although it took hours of practice and 300 failed attempt, this successful attempt is worth a big applause! I've heard that even athletes with two legs have difficulties pulling this off!

I'm inspired!
