Barbell Curl Standard
The standard barbell curl is a fundamental upper arm exercise targeting the biceps. Performed standing with a barbell, it isolates the biceps through a full range of motion to build arm strength and muscle mass.
How to do it
- Stand upright holding a barbell with an underhand grip, hands shoulder-width apart.
- Keep your elbows close to your torso and your upper arms stationary.
- Curl the barbell upward by contracting your biceps until the bar is at shoulder level.
- Pause at the top of the movement and squeeze your biceps.
- Slowly lower the barbell back to the starting position and repeat for the desired number of repetitions.
Form cues
- Keep your elbows locked by your sides
- Squeeze your biceps hard at the top
- Lower the bar slowly under control
- Stand tall with a proud chest
Breathing: Exhale as you curl the weight up, and inhale as you lower it back down with control.
Common mistakes
- Using momentum by swinging the body, which reduces the work done by your biceps.
- Allowing elbows to drift forward, which shifts tension away from the biceps onto the front shoulders.
- Using a grip that is too wide or narrow, which can cause discomfort in the wrists and elbows.
Muscles worked
Primary: biceps. Secondary: lower arms, shoulders.

Should I use a straight bar or an EZ curl bar?
A straight bar is standard, but if it causes wrist or elbow discomfort, an EZ curl bar is a joint-friendly alternative.
Why do my lower arms hurt during this exercise?
Forearm fatigue is normal since your lower arms help grip the bar, but sharp pain means you should lighten the weight or check your wrist position.
How often can I train my biceps?
2 to 3 times per week with at least one rest day between sessions is plenty for most beginners.
