i saw this guy that was only 5’7 and he could jump 4 feet 4 inches in the air so he could dunk the ball.

how can you improve your leg muscles so you can jump as high as nba players?

Can you recommend me some exercises?

wat is the correct way (the mechanics) to help you jump higher?

I’m a healthy 6’2" in my freshman year… but i can’t jump worth anything.

-Are there any key groups of leg muscles I need to work on?
- Drills I could do to maximize the height in my jump?
-Techniques I need to work on?

During a vertical jump, a person crouches down to lower her or his center and then leaps straight up. The leg muscles essentially do all the work, accelerating the body over a push-off distance of about 1/3 m. Typically, people can support an additional load using the legs equal to their own weight, but only with considerable effort. Let’s suppose then that our person can push off with a muscle-force equal to 1.5 times body-weight. Neglecting losses due to friction, how high can our friend jump?

I’m trying to improve my vertical. If I just walked around everywhere with 10 lb (5lb each) ankle weights on for a while, would that help explosiveness in my legs to jump higher? Would it not help my vertical and just add some endurance to my leg muscles?

I am very athletic and have strong leg muscles but my vertical isnt as high as i want it.
I play volleyball, but if i lost a couple pounds would that help me increase my vertical jump?
