Setup
Sit at a preacher bench with your upper arms resting flat on the angled pad, chest against the top. Grip the barbell with an underhand grip, shoulder-width apart, arms fully extended.
How to do it
- Keep your upper arms pressed firmly against the pad throughout the entire movement.
- Curl the bar upward by contracting your biceps until your forearms are vertical.
- Squeeze hard at the top position for a brief moment.
- Lower the bar with control until your arms are fully extended again.
- Avoid letting your elbows lift off the pad or sliding your body upward.
Watch out for
- ✗Lifting the elbows off the pad to gain momentum instead of isolating the biceps.
- ✗Using too much weight and only performing partial repetitions at the top.
- ✗Dropping the weight quickly on the way down instead of controlling the eccentric portion.
