The suspender biceps curl uses suspension straps anchored overhead to load the biceps brachii with your own bodyweight — the primary mover responsible for elbow flexion. By walking your feet forward to increase the angle of lean, you can scale resistance without changing the weight, making it a practical upper-arm exercise for any setting where suspension equipment is available.

How to do the Suspender Biceps Curl

  1. 1Anchor the suspension straps at a fixed point above head height so both handles hang at roughly upper-chest level when you stand beneath them.
  2. 2Face the anchor point and grip each handle with an underhand (supinated) grip, palms facing up.
  3. 3Walk your feet forward beneath the anchor until your body is at an angle to the floor — about 45° for moderate difficulty. The more horizontal you are, the harder the exercise.
  4. 4Extend your arms fully so that your weight is supported through the straps, and keep your body in a rigid straight line from head to heels with your core braced.
  5. 5Keeping your upper arms stationary and elbows pointed toward the floor, curl your hands toward your temples by bending your elbows.
  6. 6Continue curling until your hands are at forehead height and your elbows are fully flexed, pausing briefly at the top.
  7. 7Lower yourself under control back to the fully extended starting position, resisting the pull of gravity throughout the descent.
  8. 8Complete all reps, then walk your feet back toward the anchor to release the tension before stepping out of the straps.

Form tips

  • Keep your upper arms pinned in place throughout the set — only your forearms should move. Any drift of the elbows forward reduces tension on the biceps.
  • Control the lowering phase deliberately. The eccentric (descent) portion produces as much biceps stimulus as the curl itself; resist the urge to drop back quickly.
  • Adjust difficulty mid-set by stepping your feet slightly backward (easier) or forward (harder) without resting — this lets you extend a set once you reach failure at a given angle.
  • Keep your hips level and your core engaged from start to finish. Allowing the hips to sag shifts stress off the upper arm and onto the lower back.

Common mistakes

  • Swinging the hips or bridging the lower back to help complete a rep. This turns the movement into a partial body row and removes tension from the biceps brachii.
  • Letting the elbows drift forward during the curl. When the upper arms move, the range of motion shrinks and the biceps no longer work through their full length.
  • Using too little lean angle. If the straps are nearly vertical, resistance is minimal and the exercise is too easy to be effective — walk forward until you feel genuine load at the bottom of the curl.
  • Rushing the descent. Dropping back to full extension quickly shortens the time under tension and cuts the stimulus in half; aim for a 2–3 second lowering phase.
  • Starting with the wrists curled or the grip already flexed. Begin each rep with fully extended arms and a neutral wrist to ensure the biceps initiate the movement.

Frequently asked questions

What muscles does the suspender biceps curl work?

The primary mover is the biceps brachii, the muscle on the front of the upper arm responsible for elbow flexion. Because the exercise is a strict curl with no pressing or rowing component, it keeps the focus on that upper-arm muscle throughout the movement.

How do I make the exercise harder or easier?

Walk your feet forward (more horizontal body position) to increase resistance, or step them back toward the anchor (more upright position) to decrease it. No equipment change is needed — body angle is your only variable.

Is the suspender biceps curl suitable for beginners?

Yes. Beginners can start with a steep body angle (close to upright) where bodyweight resistance is low, then progress gradually by walking forward as strength improves. The suspension strap also provides some wrist stability that dumbbells do not.

How many sets and reps should I do?

For strength, aim for 3–4 sets of 6–10 reps at a body angle that makes the last 2 reps challenging. For hypertrophy or endurance, use a shallower angle and target 10–15 reps per set. Rest 60–90 seconds between sets.

What is the difference between a suspension biceps curl and a dumbbell biceps curl?

A dumbbell curl applies constant downward load from gravity regardless of joint angle. A suspension curl creates resistance that peaks when your arms are extended and your body is most horizontal, shifting the difficulty profile toward the stretched position of the biceps — which can be a useful complement to free-weight curls.
