How do I increase my vertical without spending a lot of time in the gym?

There are many jump workouts out there to improve your vertical jump. Few are worthwhile, but you'll love this one. You will have to work your butt off for about 20 minutes three days a week. It guarantees to add 8 to 14 inches on your vertical leap.

Air Alert is one of the best. Try it out. If you need more information, contact Derek.
