One, half squat jump

At the beginning, squat down to the position of 1/4 and put your hands in front. Jump at least 20 cm to 25 cm from the ground. If it's easy for you, you can jump to 25cm-30cm. When you are in the air, you need to put your hands behind your back. When landing, finish it once. Next, repeat the above steps.

Second, lift your toes.

First, find a step or a book to pad your feet, then put your toes on it, raise your heels to the highest point without touching your toes, and then slowly put them down, all at once.

Third, the steps

Find a chair, put one foot on it, jump as far as possible at 90 degrees, change feet in the air, put it on the chair and repeat 2, put the original jumping foot back on the chair and complete another jump.

Fourth, vertical jump

Straighten your feet, shoulder-width apart, and "lock" your knees with your calves. Bend your ankles and try not to bend your knees and land, then take off quickly and do it at once. This is very difficult. I can help you jump with my hands.

Five, tiptoe jump

Stand on tiptoe to the highest point and take off quickly with tiptoe, and the take-off shall not exceed 1.5 or 2.5cm.

Sixth, jump?

Stand, Squat (Half Squat) Put the basketball on your chest, look forward, keep your back straight, and lift your toes. If you want your thighs to jump 90 degrees to 8cm- 13cm, you must keep the posture of the second step on the ground. If you want to jump 15, you need to jump 8 cm- 14.
