海豚踢还能在垂直的状态下完成,这真正强调踢腿的速度和力量。Michael用一条负重腰带在训练中增加难度。我们认为这能帮助他在比赛中转身离开池壁后提高速度。
(The body dolphin can also be performed in a vertical position which really emphasizes push speed and power. Michael uses a weight belt to add resistance to his exercise. We really feel that it helps him in his push off the wall.)
