I'm not sure if it has a certain name, but what I did was either with or without a weight simply go up on your tip-toes and then back down until your foot touches flat against the ground. DO not do it quickly, but rather at a slow pace. You should feel the burn in your calves after a while. I feel that this helped my jump a lot for basketball. You can also try standing on one foot and doing this. It requires some balance once you start to tire out. I wish I could elaborate more, but this is simply all I did aside from training at basketball practice. I hope it works as well for you as it did for me. : Thanks, I've heard this suggestion a lot so far. :thumbsup: Guys if someone is obviously lying don't flame them. Negitivity isn't what I wanted from this thread. More of a sharing of experience. Besides the only ones they hurt are themselves. Must suck when you realise you brag and brag but you're really just weak. :oops: Also there's a big debate between many skinny and fat lifters... DOES BODY WEIGHT HELP YOU LIFT MORE?
