how to increase vertical leap?

I suggest constant practice on jumping. Jogging with a bagging around your waist or in your feet, and do a small jumps. Exercise your lower muscles. I guess that would help.

Jumping is a wise choice,and the most important is that you should practise everyday

I think Plyotemics havn't had too much of an impact on me/my friends. i will give some experience i heard from my friend which make him a big improvement with vertical leap: 20 squats, hands on head 20 squats, hands in front 20 jumping squats 30 knee into chest jumps running stairs with ankle weights wall sits tip-toe raises (while standing on them raise your whole body) drop-jumping (start about two stairs high, fall to the ground, and as soon as you touch, jump back) 20 180 degree jumps 20 standing long jumps (bend, and jump as far as possible landing balanenced) regular jumping net touches squats holding a weight plate squats with bar behind head ankle weights with jump rope power rebounds palms on ceiling I hope it is useful and helpful to you.lol good luck
