Quickest way to gain at least 10 inches on my vertical jump?
Posted on November 23, 2009
Hey, I'm 13 year ancient guy and I'm 6'1 tall. Even though im tall i have really low vertical (22 inches) and I really want to dunk by the end of the basketball season. I tried everything alot of jumping programs (AA, VJB, etc) but none of them worked. Can you tell how long it'll take. Thanks for all the help.
