Improves your jumping! Take a board about 3-5 feet long and 2-3 inches
high and put the top of your foot on the board and raise your-self up on
your tippy toes and hold for 1 second (do slowly) and repeat 20 times a
day! Get a bigger board! If you feel a pain that is good!

這種練習是讓大個子球員能增進彈跳能力。找一塊3-5吋長，2-3呎高的板子，把自
己的身體盡量伸展最長的程度維持一秒鐘，每天重複20次就可以增進你的彈跳能力
了，如果可以感覺到有點痛那是正常的，表示有拉開整個身體。
