How to perform
- 1.Supinated grip at shoulder width.
- 2.Elbows pinned to your sides.
- 3.Bend your elbows, curling the bar toward your shoulders.
- 4.Squeeze the biceps at the top.
- 5.Lower under control to full extension.
Common mistakes
- ●Letting the elbows drift forward
- ●Using torso momentum
- ●Not lowering all the way
- ●Gripping too wide
Proper technique
The elbows are the axis — they must stay fixed. Active supination maximizes the contraction. The controlled lowering is as important as the lift.
