Threads a little old, but for anyone that was interested. I decided to give up the P90X program I was doing due to tendinitis in my elbow from all the pull-ups. So I decided to check out The Jump Manual. Only 2 weeks in, but not terrible results so far, but nothing special. Hard to tell at 2 weeks. If you are interested follow my progress at http://dunkquest2012.blogspot.com/. I'll try to make updates in this thread for anyone that wants more info.
