If you want to learn to jump higher you will also have to train yourself accordingly.
There are two kinds of basketball players that are usually seen dunking the ball during a game: the leapers and the jumpers.
The former moves more laterally and develops strength on his hips, abdomen and upper body whereas the latter jumps more longitudinally and requires more leg strength.
However, what is quintessential to learn to jump higher is to have immense flexibility in one's body.
The flexibility allows the muscles to move easily and stretch themselves to achieve the extra height and distance.
For this you need to pay attention to your stretching exercises.
Don't dismiss them as girly or useless and a waste of time for your workout.
Stretching is the only way that your tendons and ligaments receive any tension which is extremely important when you perform these strenuous physical activities.
Without stretching not only will you be unable to perform them, but trying them suddenly will result in injuring you dangerously.
Other than stretching your workout regime should be a combination of cardio, weight training and resistance.
Remember that regardless of which you are; leaper or jumper; you need your muscles to tone up.
There are three types of muscles: skeletal, smooth and cardiac.
You need your skeletal muscles for your jumps.
These consist of fast twitch and slow twitch.
You cannot increase the number of fast twitch muscles which are necessary for your jumps.
But you can add bulk to them by consuming a proper diet and working out intensively.
