Hey guys, I just want to get a review of the Jump Manual on this site because I am hearing that it is one of the best programs out there. I was wondering if anyone has a review for it. Here's the site http://jumpmanual.com/ and Jacob Hiller's youtube channel http://www.youtube.com/user/freejumptraining. He looks like an athlete and I have never heard anyone bash him, ever, so I am assuming he is a professional trainer who gets the job done. What do you guys think?
