A curl with the upper arms supported on a pad, which keeps the biceps working through the movement and limits body swing.
Animated demo. Watch the full range of motion, then follow the steps below.
Setup
Set the pad so your upper arms rest flat along it, with your armpits at or just above its top edge.
Choose a weight you can control through the full range without bouncing.
Sit with your chest against the pad and both feet flat on the floor.
Grip the bar or EZ-bar with hands about shoulder-width apart, palms facing up.
Execution
Start with arms nearly straight, without locking the elbows.
Curl the weight up by bending at the elbow only. Keep your upper arms on the pad.
Pause briefly at the top, with the biceps fully contracted and the wrists neutral.
Lower under control until the arms are nearly straight again. Keep tension on the muscle.
Repeat for the set, then rack the weight with control.
Common mistakes
Lifting the elbows off the pad to swing the weight up.
Rolling the wrists or lifting the shoulders to finish the rep.
Dropping the weight quickly to full extension, which moves the load onto the elbow.
Choosing a weight so heavy that the lower half of the rep turns into a bounce.
Muscles worked
Primary: Biceps brachii.
Secondary: Brachialis and brachioradialis. Forearm muscles help with grip.
