Do some step exercise. Try dunking a basketball or at least touching the rim or the net. And even if you can't keep trying. That's how I increased my vertical jump.

Increase your elevation or find a court with less gravitational force.   It's  a physics thing.

Set up several sturdy wooden boxes of varying heights. Jump onto the lowest, then off, then onto the next highest, and so on, without resting in between jumps. This also works with hurdles.

Soaring over a 6'6" adult may be a stretch for just about anyone, but there is one secret I learned to improving vertical leap: practice jumping in a swimming pool.  The resistance helps improve your vertical leap distance.  Add that to general weight training, and be sure to allow enough time for recovery -- up to 72 hours between strenuous weight-bearing workouts, and you will add some inches to your vertical by the end of the year.

sure stretching will make your toe touches look better. you should definitely stretch a lot everyday. but there are other things you can do to get more height to your jump. you need to build up certain muscles in your legs along with the stretching. \n\nstart in a squat position with your legs apart. make sure the squat position is pretty low-- about halfway down. then jump up as high as you can and when your feet come back to the ground go right back into your squat position. just keep jumping like that-- jump squat jump squat.

Pylometric Exrcises can help to greatly increase the power of your kick and the height of your jump.\n\nRicochets – \n1. Mark out 15 meters with cones.\n2. Keeping your feet together, start at one cone and do small fast jumps to the end.\n3. For this exercise the emphasis should be on speed and rate of leg movement rather than height.\n4. Each 15 meters is 1 set.\n\nBounding – \n1. Mark out 12 small cones or obstacles about 3 feet apart in a straight line.\n2. Start behind the first obstacle in a semi squat position.\n3. Jump as high and far as possible over each obstacle. It's a good idea to practice first to gauge how far apart you should set the markers. Again try to minimize ground contact time.\n4. Each jump is 1 repetition.\n\nLateral Jumps – \n1. Stand alongside a bench, box or cone approximately 30cm high. \n2. Keeping your feet hip distance apart jump sideways as high over the obstacle as possible. \n3. Immediately jump back to the start position minimizing ground contact time. This counts as one repetition.\n4. Make sure you discipline yourself to jump as high as possible. \n\nSide-Jump Sprint – \n1. Place a cone 14-19 meters in front of the starting point to act as the finish line.\n2. Stand on 1 one side of a bench or obstacle, facing the starting line, with feet together.\n3. Begin by jumping sideways back and forth over the bench for 2 repetitions.\n4. On landing on the last jump, explode forward into a sprint to the finish line. \n5. Anticipate the landing and be ready to sprint forward, emphasis should be on acceleration.\n6. This counts as 1 repetition.\n\nDepth Jumps – \n1. Stand on a box, bench, or sturdy chair approximately 30-40 cm high.\n2. Step off the bench and as soon as you land explode vertically as high as you can. This counts as 1 repetition.\n3. Try to minimize ground contact time.

Couple of things...\n\n1) Jump rope...a lot\n2) Get under a basket, and jump up as high as you can for 20-25 reps, keeping both hands raised while you jump. Do this several times a day.  After a couple of weeks, you'll find yourself jumping higher and higher.  You can use the net or the backboard to guage your progress. That's the purpose of doing it under a basket.\n\nThese will strengthen your legs and improve your stamina.\n\nIf you have a coach, ask him/her about some other ways to improve your jumping. Or ask a gym teacher at your school. They'll be glad to help you.

the only way to get a better jump shot is to shoot them constantly for hours.  Remember to snap your wrist, point your arm high into the air for a better arc, and just practice!

Alright if you want to increase your vertical do this. Do Calf Raises, Leg Extensions, and especially squats, because it improves your explosiveness. And if you don't want to do any of this definitely do jump rope. Do 5 sets of a 100, and 2 sets of 200. In 2 weeks you should increase your vertical by 3 to 4 inches. But do it 5 to 6  days every week.

try doing squat excersises like standing up on the floor, bending your knees just far enough to reach the ground with your hands next to your feet and then go down another 3 inches and hold it for a minute... do this many times and for longer and longer periods. You can also try doing that same thing but instead of holding it jump up as far as you can and then as soon as you hit the ground jump again and agin for about 25 in a row. To better improve jumping power and your kick, jog bringing your knees as far up to your chest as you can , or do that jogging in place. One final excersise is more extreme and will produce amazing results, put your back against a wall and go down with your knees at 90 degrees. pretend your sitting in a chair. try to go as long as you can and push yourself past the pain limit...dont hurt yourself now :)    . Those exercises will greatly improve your Quadriceps (front of your thigh/leg area muscle) which are a must for kicking and jumping.

With practice. The basic jump is with both feet together, bouncing on the toes just to build rythym and stamina.\n\nThere are quite a number of advanced techniques, including skipping in a squat position or lifting the knees up. Jumpropeinstitute.com has illustrations of some of the exercises used: http://www.jumpropeinstitute.com/a-z_on_jump_rope.htm#sports%20training%20jumps\n\nIf you're starting out learning to jump rope, the best thing to do is to start with short intervals to improve your skill at skipping first before you start using it to try to improve other aspects of your fitness.

If you have an 8 foot vertical jump (highly unlikely) then you needn't worry about improvement. It thats an error then you could try walking around on the balls of your feet all day and also calf lifts.

sit w/ your legs spread, twist and put one hand in front, between the spread eagle, and one behind you. pick your feet up as high as you can possibly get them, and hold them there for a count of 10, make sure to keep your feet flexed and legs straight. Repeat 10 reps. This strengthens the muscles in your legs that  you use in a tt and will help you get height as well as a good stretch.
