Standing Supinated Bicep Curl
The standing supinated bicep curl uses a fully supinated grip to maximize biceps brachii activation. This grip position places the biceps in the strongest mechanical position throughout the curl, making it one of the most effective bicep strengthening exercises.
How to do it
- Stand with feet shoulder-width apart and hold a barbell with a fully supinated grip, palms facing upward.
- Let the barbell hang at arm's length in front of your hips.
- Curl the barbell upward toward your shoulders, keeping your elbows close to your sides.
- Pause at the top and squeeze your biceps.
- Lower the barbell back to the starting position in a controlled manner.
- Repeat for the desired number of repetitions.
Form cues
- Keep your elbows pinned firmly to your sides throughout the movement.
- Turn your palms completely upward before you lift.
- Squeeze your biceps hard at the very top of the curl.
- Lower the barbell slowly back down to full arm extension.
Breathing: Exhale as you curl the weight upward toward your shoulders, and inhale in a controlled manner as you lower the barbell back down.
Common mistakes
- Swinging your torso to help lift the weight uses momentum instead of your biceps, reducing the work your muscles actually do.
- Letting your elbows drift forward changes the angle and takes tension off the biceps at the bottom of the movement.
- Using too much weight can force you to compromise your form and strain your lower back.

Why do my palms need to face upward?
A fully supinated grip places the biceps brachii in its strongest mechanical position to maximize muscle activation.
What should I do if I feel this in my lower back?
Lower the weight and focus on keeping your torso still. Swinging usually means the barbell is too heavy.
How many days a week should I do bicep curls?
Two to three times per week with at least one rest day between sessions is plenty for recovery and growth.
