Instructions
Preparation
- Sit on curl machine placing back of arms on pad. Grasp lever
handles with underhand grip. Align elbows at same pivot point
as fulcrum of lever.
Execution
- Raise lever handles toward shoulders. Lower handles until
arms are fully extended. Repeat.
Comments
- Seat should be adjusted to allow arm pit to rest near top
of pad. Back of upper arm 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 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.
