  • Description

产品名称:两用拉力器

功能:单用,双用,三用

 

拉簧:5根

彩盒包装,每盒一只,一件12个

 

两种用途分别是:练习臂力,练习手握力

 

作用:拉力器锻炼的好处在于:肱二头肌是一块有两个肌头的肌肉,其主要作用是屈臂。在屈臂时,同样也用到了另外一块肌肉——肱肌。而只有在做一些前臂上抬的运动时,如高位拉力器弯举或反式高位拉力器玩具,肱肌才能得到充分锻炼。此外,前臂上部的主要肌肉肱挠肌,在屈臂动作中也起了不少作用。而通过拉力器侧弯举可以使肱挠肌得到强化。

下面是一些锻炼方法:
  动作:

  (1) 双手高位拉力器弯举

 (2) 站立双手拉力器弯举

(3) 站立单手拉力器弯举
  单手的锻炼能使效果更集中,同时也可以让你有机会运用翻掌动作(掌心向内转至掌心向上),以充分刺激肱二头肌。

 

 

动作:尽量保持你的上臂固定不动,肘关节弯屈,以二头肌之力将把手经胸前拉向肩部。当你达到肌肉最大收缩位置时,肘部应正好指向低位滑轮。然后回复至开始姿势。两臂交替进行
