Lever Preacher Curl (no seat)

Instructions

Preparation

Stand facing behind arm pad, opposite side of lever handles. Place one foot foward under arm pad and opposite foot back on foot bar. Lean over arm pads and grasp handles with slightly narrower than shoulder width underhand grip. Squat down and position back of upper arms on arm pads.

Execution

Raise lever handles toward shoulders. Lower handles until arms are fully extended. Repeat.

Comments

Arm pit to rest near top of pad. Back of upper arm should remaining on pad throughout movement. Notice that this machine has secondary lever so elbows are not aligned with primary fulcrum.
 
Long head (lateral head) of biceps brachii is activated significantly more than short head (medial head) of biceps brachii since short head enters into active insufficiency as it continues to contract. Long head of Triceps Brachii is only significant activated as antagonist stabilizer when it approaches passive insufficiency as elbow nears full flexion. Also see movements performed on machine with no seat and arms positioned higher.
