Standing Hammer Curl With Resistance Bands (Anchor)
Build thick biceps and a powerful brachioradialis with constant band tension through every degree of the curl.
Primarily trains: Primarily develops the brachioradialis and brachialis, with strong secondary recruitment of the biceps brachii, using a neutral (hammer) grip throughout the movement.
Step-by-step demonstration
3–4 sets × 12–15 reps with 45–60 s rest; the continuous band tension and isolation nature of this movement make it best suited to hypertrophy-focused rep ranges — choose a band resistance that makes the final 3 reps challenging without form breakdown.
2-1-2 — a 2-second concentric builds motor control against variable band resistance, a 1-second squeeze maximises peak contraction, and a 2-second eccentric exploits the bands' unique ability to load the lowering phase.
Inhale at the bottom before you initiate the curl; exhale steadily through the concentric as you lift, and inhale again as you lower under control.
Step 1 of 2
Setup
Get into position before the first rep.
- 1Fix the door anchor at floor level and thread the resistance band through it; close the door fully and confirm there is no slip when you pull.
- 2Attach ankle straps to each end of the band, or grip the sub-handle holders of a tube set — fingers through the loop, thumb outside, forming a solid fist with palms facing each other (neutral grip).
- 3Stand facing away from the door, approximately 1.2–1.5 m (4–5 ft) from the anchor point, feet hip-width apart.
- 4Draw your shoulder blades down and back, chest tall, and hinge very slightly forward at the hips and ankles to pre-load the band and keep tension in the bottom position.
- 5Let your arms hang fully extended at your sides, elbows soft, palms facing your thighs — confirm the band is already under light tension before rep one.
Step 2 of 2
Execution
The actual movement, one rep.
- 1Brace your core and pin your elbows firmly against your ribcage — they must not travel forward, backward, or flare outward during any phase of the lift.
- 2Drive both forearms upward in a controlled arc, maintaining the neutral (palms-facing-in) grip as you curl the handles toward shoulder height.
- 3Squeeze the brachioradialis and brachialis hard at peak contraction when your hands reach approximately chest/shoulder height; do not allow your elbows to drift forward to 'cheat' the top position.
- 4Reverse the movement under control, resisting the band's pull as you lower your forearms back to the fully extended start position.
- 5Reset your brace and tension before initiating the next rep — do not let the band yank your arms back passively.
Form cues
What a good coach would say in your ear.
- Elbows nailed to your ribs — if they move, the rep doesn't count.
- Keep your wrists flat and rigid; no curling or bending of the wrist joint.
- Slight forward lean from the hips, not the lower back — your spine stays neutral throughout.
- Squeeze at the top as if you're cracking a walnut between your forearm and upper arm.
- Control the descent — the eccentric phase is where bands earn their advantage over free weights.
Avoid these
Common mistakes.
The technique errors that quietly undo your training.
- Elbows drifting forward on the concentric: this transfers load to the anterior deltoid and reduces brachioradialis stimulus — keep elbows pinned back.
- Using a supinated (palms-up) grip instead of neutral: this converts the exercise into a standard bicep curl and loses the brachioradialis emphasis that is the entire point of the hammer variation.
- Leaning the torso back aggressively to complete the rep: lumbar hyperextension turns the curl into a partial body row and loads the spine unnecessarily — reduce band resistance instead.
- Allowing band recoil to control the eccentric: passive lowering eliminates the time-under-tension benefit of bands — resist the pull deliberately over at least 2 seconds.
- Standing too close to the anchor so the band goes slack at the bottom: this removes tension from the start position and negates the bands' constant-resistance advantage — step further from the door.
Variations & progressions
Make it harder. Make it easier. Make it fit.
- Alternating single-arm hammer curl (band): reduces demand per set, allows focus on unilateral control and symmetry.
- Incline forward-lean hammer curl (band): increase the forward hinge to roughly 30–45° to shift the resistance curve and increase stretch-position loading.
- Dumbbell hammer curl: a useful free-weight regression when a door anchor is unavailable, though the resistance curve is less uniform.
- Cable rope hammer curl (low pulley): the closest machine equivalent — provides comparable constant tension and is a good gym-based progression when higher absolute loads are needed.
Safety
Inspect the band and door anchor for fraying, nicks, or anchor slippage before every session — a snapped band under load can cause facial or eye injury. Avoid this exercise if you have an active elbow tendinopathy (lateral or medial epicondylitis) or a recent biceps tendon strain; the constant tension from bands removes the rest point that free weights provide at the bottom, increasing cumulative tendon load. Individuals with shoulder impingement should confirm the elbows-at-sides position is pain-free before loading. Stop immediately if you feel sharp pain at the elbow joint, forearm, or wrist rather than muscular fatigue.
