Blind Soccer World Cup

Cnn reports on the blind soccer World Cup. While I know that many visually impaired people participate in active sports, I have never heard about soccer specifically for the legally blind. According to the CNN report, referees calm down the crowd when they get too loud and halt play when planes fly overhead. The players have guides who tell them when to kick for a goal. I think this is a great example of adapting traditional activities for the disabled.

Now can someone tell me how to lift weights (upper body workout) without using my hands?
