*People who tell you that it's impossible to add 10 inches to your vertical leap in 12 weeks are not familiar with all the methods at their disposal for increasing vertical jump explosion. There are exceptions of course and each person is unique. But, to this day I have not had one person complete this training properly and not be 100% satisfied with the results.
Many are prone to thinking that because they have tried and failed with many different techniques, that they cannot possibly increase their vertical. The techniques in the Jump Manual work. Research proves it, individual case studies prove it, and every week athletes are putting it to the test. If you are not completely satisfied with your results within 60 days, just let us know and we'll either work with you until you are satisfied or give you a full refund.
