Standing One Arm Preacher Curl (Anchor) With Bands

Isolate each bicep head through full range of motion using band resistance and your own arm as a preacher pad.

Primarily trains: Primarily develops the biceps brachii (both heads) through strict elbow flexion isolation, with the inactive arm replicating the angled support of a preacher bench to eliminate momentum.

Standing One Arm Preacher Curl (Anchor) With Bands — demonstration

Step-by-step demonstration

Sets & reps

3–4 sets × 10–15 reps per arm, 45–60 s rest between arms; this rep range targets hypertrophy, which suits the strict-isolation nature of the exercise — prioritise full range of motion and control over band thickness.

Tempo

3-1-2 — a 3-second lowering phase maximises time under tension against the band's pull, a 1-second peak squeeze reinforces the mind-muscle connection, and a 2-second curl maintains control through the concentric.

Breathing

Exhale as you curl the handle upward through the concentric phase; inhale slowly as you lower back to full extension.

Step 1 of 2

Setup

Get into position before the first rep.

1Anchor the resistance band to the bottom of a door using a door anchor, ensuring the anchor point is secure before loading it.
2Stand facing the door, far enough away that the band is already under light tension with your working arm fully extended — no slack at the start position.
3Grip the band handle with your working hand, palm facing up (supinated grip), arm extended straight toward the anchor point.
4Place your inactive arm across your torso and press the back of its wrist firmly against the underside of your working arm's upper arm — this acts as your preacher pad, locking the elbow in place.
5Stand tall: feet hip-width apart, core braced, chest up, shoulders level and away from ears.

Step 2 of 2

Execution

The actual movement, one rep.

1Begin with your working arm fully extended toward the anchor, elbow soft — not hyperextended — and wrist neutral.
2Initiate the curl by flexing only at the elbow; drive your palm toward your shoulder while keeping the upper arm pinned against your inactive wrist throughout.
3Continue curling until your hand reaches chest or shoulder height — stop before your elbow lifts away from the makeshift pad.
4Hold the peak-contracted position briefly, feeling the bicep fully shortened.
5Lower the handle in a controlled manner back to full elbow extension, resisting the pull of the band on the way down.
6Reset tension and posture before initiating the next rep.

Form cues

What a good coach would say in your ear.

Upper arm stays pinned — if your elbow drifts forward or upward, you've lost the isolation.
Keep your wrist straight; don't let it flex or collapse toward you at the top.
Drive the pinky side of your hand toward your shoulder to encourage full supination and peak bicep contraction.
Stand tall the entire set — don't lean back or shrug to assist the curl.
Squeeze hard at the top for a count; the band's increasing resistance makes this the most valuable part of the rep.

Avoid these

Common mistakes.

The technique errors that quietly undo your training.

Elbow drifting away from the inactive arm's wrist: breaks isolation and shifts load onto the anterior deltoid, defeating the purpose of the preacher setup.
Standing too close to the anchor: removes tension at the start of the movement, eliminating the resistance curve advantage bands provide over free weights.
Letting the wrist flex at the top: shifts stress to the forearm flexors and reduces bicep peak activation.
Rushing the eccentric (lowering) phase: the band pulls back with increasing force — controlling this portion is where significant hypertrophy stimulus is generated.
Rotating the torso to assist the curl: introduces momentum and unloads the bicep, making the exercise far less effective and stressing the lumbar spine unnecessarily.

Variations & progressions

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

Seated band preacher curl: sit on a chair facing the anchor for greater lower-body stability, useful when learning the elbow-lock technique.
Two-arm standing band curl (regression): remove the preacher-pad constraint and perform bilateral curls to build base strength before adding the isolation component.
Increase band resistance (progression): step farther from the anchor or use a heavier band once you can complete 15 clean reps; avoid compensating form for extra resistance.
Dumbbell preacher curl on a bench (equipment alternative): the classic version using an EZ-bar or dumbbell on a preacher bench, which provides a fixed pad and may be preferable for those with shoulder or postural asymmetries.

Safety

Avoid this exercise if you have an active bicep tendon injury, elbow hyperextension issues, or recent elbow surgery — the full stretch under band tension at the bottom position places significant stress on the distal bicep tendon. If you feel a sharp, pinching pain in the front of the elbow at any point in the range of motion, stop immediately and do not push through it. Those with shoulder impingement should monitor whether holding the inactive arm across the chest aggravates symptoms; if so, use a physical preacher bench instead. Ensure the door anchor is rated for resistance band use and check for wear on the band before each session.
