How to Barbell Preacher Curl
Barbell Preacher Curl muscles worked: Biceps
Form
- 1. Press your armpits against the pad.
- 2. Grab the barbell with shoulder-width grip, palms facing up.
- 3. Lift the barbell using only your biceps without any body or shoulder momentum.
- 4. Slowly lower the barbell while feeling the resistance of the weight, keeping your shoulders and elbows fixed.
- 5. Do not fully extend your arms; keep them slightly bent to maximize relaxation.
Coach's Comment
- 1. Fix your elbows on the pad and control the weight slowly.
- 2. If you straighten your arms too much, it puts strain on your elbow joints, and using body momentum puts strain on your lower back.
- 3. If you feel pain, lower the weight by 10–20%.
