You probably have to do leg exercises like squats, leg presses, lunges, step-ups, etc.

well first you need to build up your leg muscles
also jumping on the trampoline will help
but you need to do leg exerscises and things a lot, lots and lots of practice
dont expect to see results right away
its not going to happen fast, nothing will
it depends on how long you practice building up the muscles for

First of all you cant jump higher in a short amount of time. It will take time and also a little bit of effort. One of the best exercises that you can use is airalert 3. It has a number of exercises that will help your vertical jump. Type it in at google and it will be the second link. Good Luck!
