Lying Biceps Curl With Resistance Bands (Arms Up)

Isolate your biceps under constant tension by curling against a top-anchored resistance band from the floor.

Primarily trains: Develops the biceps brachii (with brachialis and brachioradialis as synergists) through a supinated curl pattern with peak loading at the stretched (start) position — the inverse of a free-weight curl.

Lying Biceps Curl With Resistance Bands (Arms Up) — demonstration

Step-by-step demonstration

Sets & reps

3 sets × 10–15 reps, 60 s rest — the constant band tension and stable body position favour hypertrophy; work in the 10–15 rep range and progress by moving to a heavier band once all reps feel controlled.

Tempo

3-1-2 — a 3-second eccentric maximises time under the band's peak tension at the stretched position, the 1-second pause eliminates momentum, and a 2-second concentric keeps the contraction deliberate.

Breathing

Inhale fully before you curl; exhale steadily through the concentric (curl up), then inhale on the controlled eccentric (lower down).

Step 1 of 2

Setup

Get into position before the first rep.

1Attach a door anchor to the top of a closed door (above the hinge line, as high as possible).
2Clip a handle to each end of the resistance band and loop the band through the anchor.
3Lie on your back with knees bent, feet flat on the floor, and the soles of your feet touching the base of the door directly below the anchor.
4Grasp one handle in each hand with a supinated (palms-up) grip.
5Extend both arms fully toward the anchor so the band is already under tension before your first rep — this is your start position.

Step 2 of 2

Execution

The actual movement, one rep.

1Press your upper arms and elbows lightly into the floor; they must stay fixed and pointing toward the anchor throughout.
2Exhale and curl both handles toward your face by flexing the elbows, keeping palms facing up.
3Continue until your elbows are fully flexed (forearms roughly perpendicular to the floor or handles near forehead level) — pause briefly at peak contraction.
4Inhale and slowly lower the handles back to the fully extended start position, resisting the band's pull rather than letting it snap your arms down.
5Maintain tension at the bottom — do not let the band go slack.

Form cues

What a good coach would say in your ear.

Pin your upper arms to the floor — no rowing or shoulder elevation.
Keep palms facing the ceiling from start to finish.
Control the descent; the eccentric is where the bands are most loaded.
Feet stay flat on the floor — brace your core so your hips don't hike.
Full range: arms completely straight at the bottom, elbows fully closed at the top.

Avoid these

Common mistakes.

The technique errors that quietly undo your training.

Letting the elbows lift off the floor and move toward the chest — this recruits the front deltoid and reduces biceps isolation.
Allowing the wrists to pronate (palms rotating inward) mid-curl — this shifts load away from the biceps brachii onto the brachioradialis.
Dropping the weight too quickly on the return — the stretched band produces the highest resistance at the start position; a fast eccentric wastes the primary loading stimulus.
Choosing a band so heavy that the back arches off the floor — lumbar hyperextension under band pull can compress the lower spine.
Not fully extending the arms at the bottom — shortening the range of motion eliminates the loaded stretch that makes this variation uniquely effective.

Variations & progressions

Make it harder. Make it easier. Make it fit.

Single-arm lying curl — trains each arm independently to correct left-right strength imbalances.
Lying hammer curl (neutral grip) — rotate handles so palms face each other to shift emphasis toward the brachialis and brachioradialis.
Seated or standing biceps curl with top anchor — same band angle but more core demand; use as a progression once the lying form is solid.
Decline bench lying curl — elevate your torso slightly on a low decline bench to increase the stretch on the long head of the biceps.

Safety

Avoid this exercise if you have acute elbow tendinopathy or a recent biceps tendon injury, as the high load at full extension places significant stress on the distal tendon. If you have lower-back sensitivity, ensure the core is braced and the band tension does not pull your lumbar spine into hyperextension — reduce band resistance if you cannot keep your lower back in contact with the floor. Stop immediately if you feel sharp or pinching pain at the front of the shoulder, elbow joint, or forearm.
