Because a band gets heavier as it stretches, the hardest part of this curl lands near the top, right where your biceps are fully shortened. Working one arm at a time keeps the anchored band stable underfoot and gives each side a brief rest, so it suits higher-rep sets at home or while traveling.
How to do the Alternating Banded Biceps Curl
- Stand with your feet shoulder-width apart and hold the band with an underhand grip, palms facing up.
- Keep your elbows close to your sides and slowly curl one arm up towards your shoulder, squeezing your biceps at the top.
- Lower the arm back down to the starting position and repeat with the other arm.
- Continue alternating arms for the desired number of repetitions.
Tip: Lower for three seconds and stop just short of locking out the elbow to keep the muscle under tension.

Common mistakes
- Elbows drifting forward — as the elbows come up the front delt starts to lift the weight; pin the elbows to your sides and let only the forearm move.
- Swinging from the hips — a small rock backward on each rep means the weight is too heavy; drop it and curl from a dead stop.
- Cutting the bottom short — stopping with the elbow bent shortens the range where the biceps are stretched; lower until the arm is nearly straight.
- Wrists curling at the top — flexing the wrist toward you brings the forearm flexors in; keep the wrist neutral or slightly extended.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Muscle growth | 3–4 × 10–15 | 60–90 s |
| Endurance / finisher | 2–3 × 15–20 | 45 s |
| Strength | Not ideal — pick a compound lift for the same muscle | — |
Curls go at the end of a pull session or arm day, after the rows and pulldowns that also load the biceps. Superset them with triceps pushdowns on the same cable stack or triceps extensions with the same dumbbells.

What can I do instead of the Alternating Banded Biceps Curl?

How many sets and reps should I do?
It depends on your goal. For the Alternating Banded Biceps Curl, a sensible starting point is muscle growth: 3–4 × 10–15 with 60–90 s rest; endurance / finisher: 2–3 × 15–20 with 45 s rest. Do it after your compound lifts. It is a finishing movement, not the main event.
