How to do it
Adjust the seat and place your arms on the pad. Grip the handle and curl it toward you, squeezing your biceps, then lower.
- 1Position your upper arms on the pad and curl the handle toward you, feeling an isolated contraction in your biceps
- 2Lower the weight slowly to feel a stretch at the bottom without losing tension
- 3Use a full range of motion while keeping your upper arms pinned to the pad
Common mistakes
- Don't lift your elbows off the pad or swing your body to move the weight
- Avoid cutting the range short; extend almost fully for a complete stretch
- Don't let your wrists bend backward or forward excessively
