1 loose extra weight #2 you have to be fit #3 lotsa foot work, joogging ,bicycle, #4 maybe a bit of leg weight lifting, make sure you do it properly other wise you might end up injured. #5 shoe grip, depends on what sort of floor you play on. #6 the last thing in my mind is. most shorter people jump higher than taller people because of better movement, they have lesser weight than taller people and more athletic. smaller player have better movement, there more athletic than taller ones. tall players are slow they can't move much, limited movement not like the smaller ones they are flexible on anything when it comes to playing basketball, tall players are only good in rebounds and thats about it when it comes to basketball. your pretty tall for a 12 yrs old. don't worry theres still lotsa time for your body to develop. AND THE MOST IMPORTANT THING IS YOU HAVE TO BE ALWAYS FIT AND HEALTHY STRONG BODY SPECIALLY FOR TALLER PLAYERS. AND NO SMOKING OR DRINKING BECAUSE THAT WILL MAKE YOUR BODY TEAR APART. i am proud to say im only 163 cm and man when i play with big people i just smashed the hoops and layups. tall players couldn't keep up with me because i am just to quick for them and they are just to slow when it comes to movement, but the only thing there good at is that on rebounding but still with my height i can still pull some rebounds of the taller players even if i am not that tall….don't worry kid. you still got lotsa years to go before you be a good player… just remind you to keep playing basketball everyday…specially with footworks….

In order to jump higher and increase your vertical jump for basketball, you must do the right exercises and know what you are doing. Many people who want to jump higher train wrong, they train for endurance and not for muscle explosion.

One of the biggest mistakes guys make in trying to jump higher is they train for endurance and strength only and not for muscle explosion. To jump higher, you want to train your body for explosion, which is a combination of strength and quickness. Calf exercise, squats, lunges,and other strength building exercises are important for building strength and jump roping, and running stairs are good for endurance, but to increase your vertical jump, you must also train for muscle explosion, which involves plyometric exercises.

Plyometrics is where you simulate sports movements and concentrate on simulating jumping movements (explosive motions).
Plyometric exercises are used to develop your quick twitch muscles, used to increase your explosion.

Quality of the exercise is MUCH more important than quantity. 5 reps of proper form will get you in the air much higher than 20 reps of poor form. Also, if you want an explosive vertical, you must train that way! Do every exercise as explosively as possible and go for maximum height. You're vertical will improve like you never thought possible if you go for more distance on every jump. This is telling your body that you need to get HIGHER.

Besides plyometric exercises, there are other important variables involved to maximize your vertical jumping.
Some includes reducing body fat, proper nutruition, increasing flexibility,
