- Sit on curl machine. Grasp lever handles with underhand grip.
Align elbows at same pivot point as fulcrum of lever while 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 remain on pad throughout movement.
If machine has secondary lever (as shown), it is not as essential
to position elbows in-line with the primary fulcrum, as would
otherwise be required.
- 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 significantly activated as antagonist stabilizer
when it approaches passive
insufficiency as elbow nears full flexion. Also see movement
on preacher machine with arms
Stabilizers (see comments)
