He's 5' 11" and dunking...

"Jacob, I’m 6 foot on a good day. Been trying to get my vertical to 50″ and I’m gonna do it. With The Jump Manual training I have been able to get my vertical to the upper 40s. Now I can 360 two handed dunk, alley oop, and dunk in between my legs. I have gained well over 17 inches using the trainings, not to mention my first step is untouchable bro. Thanks for giving out the real deal."
