Band Biceps Curls (How To, Muscles Worked, Benefits)

Band Curls are a simple but effective way to train the biceps using a resistance band. Unlike dumbbells or barbells, the resistance increases as the band stretches, keeping constant tension on the muscles.

This makes them a great option for home workouts, warm-ups, or as a finisher in arm training.

Primary Muscles Worked: Biceps Brachii
Secondary Muscles Worked: Forearms (Brachioradialis, Grip)
Equipment Needed: Resistance Band

How To Do Band Curls

Step-by-Step Instructions

Set-Up:
- Stand with feet shoulder-width apart, resistance band anchored under your feet.
- Hold the ends of the band with an underhand or neutral grip, arms fully extended, and elbows tucked close to your sides.
Execution:
- Curl your hands upward toward your shoulders, keeping elbows pinned at your sides.
- Squeeze the biceps hard at the top.
- Slowly lower your hands back down with control until arms are fully extended.
Tips for Proper Form:
- Keep tension on the band. Don’t let it snap back down.
- Avoid swinging your elbows forward; isolate the biceps.
- Control both the upward and downward phases of the curl.

Key Benefits

Provides constant tension throughout the range of motion.
Portable and joint-friendly alternative to free weights.
Great for warming up or finishing biceps work.

Modifications and Variations

Easier Option:
- Use a lighter resistance band.
- Anchor the band higher (under one foot instead of both) to reduce tension.
Harder Option:
- Use a thicker band or shorten the band for more resistance.
- Perform single-arm band curls for unilateral focus.
- Add a pause at the top or slow the lowering phase for more time under tension.

Common Mistakes

Elbows Moving Forward: Keep elbows pinned to your sides.
Letting the Band Snap: Control the eccentric (lowering) phase.
Using the Shoulders: Keep tension in the biceps, not the upper body.

Reps and Sets Recommendations

For Hypertrophy: 3–4 sets of 10–15 reps with steady tension.
As a Finisher: 2–3 sets of 15–20 reps for a pump.
For Warm-Up/Activation: 2 sets of 12–15 light reps before heavier pulling or curling work.

Resistance Band Bicep Curls Alternatives

Don’t have a resistance band? Here are a couple of alternatives you do instead.

Barbell Curls

If you don’t have a resistance band, don’t worry, Barbell Curls are a perfect (some would even say better) alternative to their banded version.

Stand tall, grip the bar shoulder-width apart, keep elbows tucked and curl the bar up to shoulder level. Slowly lower back to the starting position and repeat for the desired number of reps.

DB Curls

Dumbbell Curls are another good alternative to work those biceps with a different piece of equipment.

Again, the movement itself doesn’t really change a whole lot, just make sure to not swing those dumbbells at the bottom. Maintain control throughout.

Best Exercise to Superset with Band Curls

Supersetting exercises is a great way to maximize your time and get your heart rate up. Here’s my favorite exercise to superset with Band Curls.

Band Triceps Pushdown

For me, this one is a no-brainer. Triceps are the best exercises to pair with biceps exercises and since you’re already using your band – Band Triceps Pushdown makes too much sense.

Loop your band around a pull-up bar (or whatever works best for you) and knock out some triceps extensions to go with your curls.
