The resistance band bicep curl is a beginner-friendly isolation exercise that uses continuous tension to challenge your arms. By stepping on a resistance band and pulling the handles or ends upward, you create a smooth line of resistance that engages your muscles throughout the movement.
This elbow flexion movement targets the biceps brachii as the main driver. It also recruits the brachialis as a supporting muscle to help bend the elbow. Because it only requires a band, it is highly accessible for home workouts or traveling.
How to do it
Stand in the middle of a resistance band with your feet shoulder-width apart and hold one end of the band in each hand. Keep your arms fully extended by your sides with your palms facing forward.
- Brace your core and keep your chest up.
- Bend your elbows to curl the band upward toward your shoulders.
- Keep your upper arms completely still and tucked against your ribs.
- Squeeze your biceps hard at the top of the movement.
- Lower your hands back down to the starting position with control.
Sets, reps and load
Aim for three sets of 10 to 15 repetitions. Rest for about 60 seconds between each set.
Choose a band thickness that allows you to complete your target repetitions with good form but leaves your biceps feeling fatigued by the final rep.
Common mistakes
- Moving the elbows forward. Keep your upper arms locked in place against your torso. Only your forearms should move.
- Using momentum. Avoid swinging your torso backward to heave the band up. Keep your core tight and use only your biceps to move the resistance.
- Rushing the eccentric. Do not let the band snap your hands back to the bottom. Take two to three seconds to lower the band.
- Flexing the wrists. Keep your wrists in a neutral position throughout the entire curl. Bending them toward you shifts the tension away from the biceps.
Make it easier or harder
Easier
- Perform the exercise seated on a chair with the band looped under your feet.
- Step on the band with only one foot to reduce the overall tension.
Harder
- Step your feet wider apart on the band to increase the starting tension.
- Pause for two seconds at the top of the contraction before lowering the band.
