- 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 one lever handle toward shoulder. Return handle until
arm is fully extended. Repeat with opposite arm. Continue alternating
movement between arms.
- 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 with both arms simultaneously.
