Lying Biceps Curl With Resistance Bands (Arms Down)

Isolate your biceps fully without spinal load — ideal for back-sensitive athletes chasing serious arm development.

Primarily trains: Develops the biceps brachii through a full range of elbow flexion against accommodating resistance, with the floor eliminating compensatory trunk movement.

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

Step-by-step demonstration

Sets & reps

3–4 sets × 10–15 reps, 60–75 s rest — the accommodating resistance and strict isolation position target hypertrophy; keep reps in the moderate range with a band tension that makes the last 3 reps genuinely challenging.

Tempo

2-1-2 — a 2-second lower builds eccentric tension, the 1-second pause at the top ensures you're not relying on elastic rebound, and a controlled 2-second curl keeps upper arms pinned.

Breathing

Exhale as you curl the handles up (concentric); inhale as you lower them back down (eccentric).

Step 1 of 2

Setup

Get into position before the first rep.

1Anchor the resistance band at floor level — loop it under the door using a low door anchor, or secure it under a heavy fixed object.
2Lie flat on your back with your head pointing away from the anchor, feet approximately 60–90 cm from the anchor point.
3Bend your knees to about 90°, feet flat on the floor to neutralise the lumbar spine.
4Grip one handle in each hand, palms facing the ceiling (supinated grip), and lay your upper arms flat against the floor along your sides.

Step 2 of 2

Execution

The actual movement, one rep.

1Begin with elbows fully extended and upper arms pressed firmly against the floor — this is your start position.
2Exhale and curl both handles upward by flexing at the elbow, keeping upper arms pinned to the floor throughout.
3Continue curling until your hands are directly above your chest and your forearms are as vertical as the band allows.
4Squeeze the biceps hard at peak contraction for one full second.
5Inhale and lower the handles slowly back toward the floor in a controlled arc, resisting the pull of the band.
6Stop just before your wrists touch the floor — maintain tension in the biceps — and begin the next rep.

Form cues

What a good coach would say in your ear.

Upper arms stay nailed to the floor for every single rep.
Lead the curl with your pinkies — keep that supinated grip all the way up.
Squeeze hard at the top, don't just bounce through the peak.
Lower with control — the eccentric is where the muscle grows.
Chin tucked, neck long — don't crane your head off the floor.

Avoid these

Common mistakes.

The technique errors that quietly undo your training.

Lifting the upper arms off the floor during the curl — this shifts load onto the anterior deltoid and removes the isolation benefit the exercise is specifically designed to provide.
Allowing the wrists to touch the floor at the bottom — this releases tension from the band and eliminates the stimulus at full elbow extension, reducing time under tension.
Using a band with excessive resistance and swinging the arms — momentum defeats the anti-cheat purpose of the supine position.
Letting the elbows flare wide — this internally rotates the humerus and reduces biceps brachii activation while stressing the elbow joint.
Holding the breath through the set — this unnecessarily elevates blood pressure and reduces rep quality; breathe rhythmically with each curl.

Variations & progressions

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

Alternating-arm lying curl — curl one arm at a time to increase unilateral focus and time under tension per set.
Single-arm lying curl with light band — regression for beginners or for addressing bilateral strength imbalances.
Lying hammer curl with band — rotate to a neutral (thumbs-up) grip to additionally target the brachialis and brachioradialis.
Lying curl on incline bench with band — elevates the torso slightly to shift peak tension further into elbow extension, increasing the stretch stimulus.

Safety

This exercise is low-risk for individuals with lumbar disc issues or spinal compression sensitivities, as the supine position unloads the spine entirely — but confirm with a physiotherapist before training through active disc pathology or acute lower-back pain. If you feel sharp pain or clicking in the elbow joint at full extension, do not lock out; stop just short of end-range. Ensure the band anchor is fully secure before each set — a sudden release under tension can cause the handles to recoil toward the face.
