All u have to do is work on ur vertical. Here are some exercises to do that.
Deep Knee Bends: Stand up. Bend your knees in a slow motion while at the same time making sure the back is kept straight. Then, crouch down slowly to the farthest you can go. Repeat the task for about 15 times. If you decide to keep doing the exercise on a regular basis, increase the repetition to 20, then 30 and so on. Doing this exercise will ensure the strength of the muscles in the leg portion are stronger by a level.
Perform the Toe Raises: Stand up, then raise your leg until you could touch with one hand the tip of a toe. Pull down and repeat on the other leg. Do the motion slowly. Make 30 to 50 repetitions for this simple exercise.
Stomach Crunches. Regular sit ups would not be helpful, but a variation to the stomach crunches would be effective. To do that, lie down the floor, make sure the back is strictly straightened. Then, rise up by initially lifting the shoulders from the floor. Do the simple task for 10 minutes, in the morning and at night.
So all u have to do is work on those and in no time you will be able to DUNK!
good luck
hope this helped ya
