Instructions
Preparation
- Sit on curl machine placing the back of the arms on pad. Align the elbows at the same pivot point as the fulcrum of the lever. The seat should be adjusted to allow the arm pit to rest near the top of the pad. Grasp lever handles with underhand grip.
Execution
- Raise the lever handles until elbows are fully flexed with the back of the upper arm remaining on the pad. Lower the handles until arms are fully extended. Repeat.
Comments
- If the machine has a secondary lever, elbows can be positioned
further away from the primary fulcrum.
- The long head (lateral head) of the biceps brachii is activated significantly more than the short head (medial head) of the biceps brachii since the short head enters into active insufficiency as it contiues to contract. The long head of the Triceps Brachii is only significant activated as an antagonist stabiliizer when it approaches passive insufficincy as the elbow nears full flexion.
