- Sit on curl machine. Grasp lever handles with underhand grip.
Align elbows at same pivot point as fulcrum of lever and placing
back of arms up on pads.
- Pull lever handles toward shoulders. Return handles until
arms are fully extended. Repeat.
- Back of upper arms should remaining on pad throughout movement.
If machine has secondary lever (as shown), elbows can be positioned
further away from 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
as it continues to contract. Long head of Triceps Brachii is
only significant activated as antagonist stabilizer when it approaches
as elbow nears full flexion. See exercise performed on alternative
machine. Also see movement on preacher
machine with arms positioned lower.
