• エクササイズ

Sit with the legs slightly apart,back straight,and the abdominal muscle contracted.
With arms extended,grasp a dumbbell in both hands with fingers crossed over each other and rest it against the things.
●Inhale and raise the dumbbell to eye level.
●Lower gently,avoiding abrupt movements.
●Exhale at the end of the movement.
This exercise mainly contracts the anterior deltoid,the clavicular head of the pectoralis major,and the short head of the biceps.
Note that all the fixators of the scapula are used during the isometric contraction,which allows the humerus to move from a stable position.
