求翻译：The full handstand pushup is an excellent basic exercise. It will teach you to use your strongest pressing muscles powerfully and with coordination. But if you want to move to very advanced unilateral handstand work you will need extremely powerful tendons, particularly around the elbows, forearms and wrists. Close handstand pushups develop that tendon strength. The close hand position makes it more difficult for the shoulder girdle to contribute to the movement, which in turn forces the elbows to become much stronger.是什么意思？
