: 這是我朋友的投球動作
: 請問有沒有什麼建議
: 相機不是很清楚還請見諒
: 謝謝
good enough, i think your friend should have been trained for a while.
tiny suggestions
1) don't curve his upper body; keep the upper body straight
2) right leg bends little too much. the whole body should go forward
driven by right leg, not go downward.
3) releasing point little too early
