Lets take a minute to look at some beneficial jumping exercises.

Jumping involve leg strength and quickness. The combination of these two things is called power. This hubpage will look at how to increase both those areas through proper training.

Rim Touches:

These are simple. You jump and touch the rim (or backboard) and try to touch it as many times in 10 seconds as possible. Speed is key here. You might sacrifice a little height for speed but that's okay. You still want to get as high as you can on each jump but not resetting will make your jump height decrease slightly.

Jumping Lunges:

Just as the name implies these are lunges where you jump as HIGH as you can and switch your feet in the air so that the opposite foot ends up in front when you land. You land going into another lunge. You don't actually move forward when doing this exercise.

Calf Raise Jumps:

These require something where your heel can go lower than your toes. From that position jump but only use your calves and not your knees (they stray straight).
