Technique
Setup
Stand holding the bar with an underhand, shoulder-width grip, arms extended at your thighs.
Movement
Curl the bar to your shoulders keeping elbows pinned at your sides, then lower slowly.
Form Tip
No swinging — if your hips kick forward to start the rep, the bar is too heavy.
Increase Difficulty
Add weight or slow the lowering to 3 seconds.
Decrease Difficulty
Lighten the bar or curl with dumbbells.
