This is a short video where Micheal Jordan is answering the question "How can I jump higher?"
Here is what he says
"I really don't understand the physics of jumping and how you increase that. The things that I can say that I did when I was a kid to improve my jumping, very basic things, I used to work on jump, I used to just try to jump and try to dunk and I guess if you exercise that muscle to that activity some how its gonna improve. How much it would improve? No one can really dictate who is gonna be the greatest leap of all time.....
One of the best training programs which will definitely add inches to your jump is the jump experts. It contains information from 13 experts in various fields related to strength and jump training who have proven track records from NFL, NBA, NCAA etc.
The e-reviewers.com website has a review about this as: While the authors (13 pro level trainers) and system of this vertical program have been around for some time, it is new to the ever evolving world of digitally delivered products. After receiving numerous requests to review the JumpExperts program and reading the claims on the site it was apparent that we needed to review this product. Our tester was a high-school junior volleyball player with above average athletic ability. He just completed the 8 week program and has seen very good results, 8.5 inches was added to his vertical, the second best of the programs we have tested.
It has a price tag of $87 and comes with 8 weeks money back guarantee. If you think that gaining some inches in jumping will improve your life then this is what you need.
