How can I increase my vertical jump in four weeks?
Posted on November 21, 2009
I will be trying out for the volleyball team this fall but I am only 5'2 so I want to increase my vertical jump. I want to be a setter but being able to block would be a bonus. I know I won't make a huge difference in such a small amount of time but a few inches would be nice.
Also I heard jumping rope helps, is this right? And can I just jump rope normally?
