Banded Bicep Curl
The resistance band curl is a biceps exercise in which you curl a resistance band, usually anchored under your feet, with your palms facing up. It works the biceps and brachialis, with the band's tension highest at the top of the curl, and suits home training, travel and high-rep arm work.
Also called: Resistance Band Curl, Band Curl, Band Curls, Band Bicep Curl · Equipment: band · Pattern: pull
Step by step
- Stand on the middle of the band with your feet about hip-width apart, and check the band for nicks or wear first.
- Hold one end of the band or a handle in each hand with your palms facing forward and your arms straight by your sides.
- Stand tall with your elbows close to your sides. Shorten your grip or widen your stance if the band is slack at the bottom.
- Curl your hands up towards your shoulders by bending at the elbows, keeping your upper arms still.
- Squeeze your biceps at the top for a moment, where the band tension is highest.
- Straighten your arms under control until they are fully extended, keeping tension in the band.
- After the last rep, let the band go slack before stepping off it.
- Elbows pinned to your sides
- Squeeze hard at the top
- Upper arms still, only the forearms move
- Control the band all the way back
- Stand tall, no swinging

What goes wrong, and the fix
Swinging the torso
Fix: Stand tall with soft knees and curl without rocking.
Elbows drifting forward
Fix: Keep your elbows by your sides and move only at the elbow.
Letting the band snap back
Fix: Take two seconds to straighten your arms, keeping the band taut.
Starting with a slack band
Fix: Shorten your grip or widen your stance until the band is taut at the bottom.
Half reps at the top
Fix: Straighten your arms fully at the bottom of every rep.
What the research says
Rehab & prehab · first choiceMuscle growthGeneral fitnessEndurance
- Bands and strength — A meta-analysis of eight trials found training with elastic bands produced strength gains similar to training with weight machines and dumbbells. It measured strength only, not muscle size.
- Muscle length — A trial found elbow-flexor training with the arm near straight produced more growth and strength than training with the elbow bent. A band loads that position least.
- Load and effort — Research finds muscle growth is similar across a wide range of loads when sets are taken close to failure, although very light loads have produced less growth. Many lifters gauge band effort by reps left in reserve.
- Rep ranges — Band curls are commonly done for 12–25 reps, with a thicker band once the top of the range comes easily.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. There is no research specific to the band curl.
