Exercise guide

Dumbbell Waiter Biceps Curl

  • Intermediate
  • Isolation
  • Rep-based
  • Upper arms

The Waiter Curl is a unique isolation movement that targets the biceps brachii, specifically emphasizing the 'peak' of the muscle by using a specific grip on the dumbbell head. This variation reduces the involvement of the forearms and brachioradialis, forcing the biceps to handle the majority of the load.

Muscles worked

Primary

  • Biceps

Equipment

  • Dumbbell

Setup

  1. Stand with your feet shoulder-width apart and a slight bend in your knees for stability.
  2. Hold a single dumbbell with both hands, placing your palms flat against the underside of the top weighted plate (the 'bell').
  3. Let the handle of the dumbbell hang vertically between your thumbs and index fingers.
  4. Start with the dumbbell at waist height, arms fully extended, and elbows tucked firmly against your ribs.

How to do it

  1. Exhale as you curl the dumbbell toward your upper chest by hinging only at the elbows.
  2. Keep your palms facing the ceiling throughout the entire movement, ensuring the top of the dumbbell remains level like a tray.
  3. Squeeze your biceps forcefully at the top of the movement for a one-second pause.
  4. Inhale as you slowly lower the dumbbell back to the starting position using a controlled three-second tempo.

Form checklist

  • Keep your elbows pinned to your sides; do not allow them to flare out or drift forward.
  • Maintain a neutral spine and avoid leaning back or using momentum to swing the weight.
  • Ensure your palms stay flat against the plate rather than gripping the handle or the edges.
  • Achieve a full range of motion by fully extending your arms at the bottom of each rep.

Pro tips

  • Focus on the mind-muscle connection by imagining you are trying to 'crush' the dumbbell head between your palms at the top of the curl.
  • Keep your wrists slightly extended (tilted back) to further isolate the biceps and minimize forearm assistance.

Make it harder

  • Slow down the eccentric phase to five seconds to increase time under tension.
  • Perform a '1.5 rep' style by curling to the top, lowering halfway, curling back to the top, and then lowering all the way down.
