Waiter Curl

A curl performed holding a dumbbell horizontally with both hands, like balancing a tray, isolating the long head of the bicep.

Setup

Hold a dumbbell horizontally, palms up underneath it. Both hands supporting the weight, like balancing a tray, arms extended down.

Movement

Curl the dumbbell up toward your chest. Keep your elbows relatively still, same general curling motion as a standard curl. Squeeze at the top. Peak contraction at the top of the curl.

Return

Lower with control. Return to the starting position, maintaining the horizontal grip throughout.

Common Mistake to Avoid

Losing control of the horizontal grip. The unusual grip requires more focus and control than a standard dumbbell curl — start with lighter weight while learning it.

Primary Muscles Biceps (long head emphasis)
Secondary Muscles Forearms

Why it matters

Holding a single dumbbell horizontally underneath, with both hands supporting it like a waiter carrying a tray, creates an unusual grip and curling angle that some lifters find emphasizes the long head of the biceps differently than a standard curl grip.

How to do it

  1. Hold a dumbbell horizontally, palms up underneath it. Both hands supporting the weight, like balancing a tray, arms extended down.
  2. Curl the dumbbell up toward your chest. Keep your elbows relatively still, same general curling motion as a standard curl.
  3. Squeeze at the top. Peak contraction at the top of the curl.
  4. Lower with control. Return to the starting position, maintaining the horizontal grip throughout.

Common mistakes

  • Losing control of the horizontal grip. The unusual grip requires more focus and control than a standard dumbbell curl — start with lighter weight while learning it.
  • Swinging the torso to assist. Same cheat-curl risk as any curl variation.
  • Using too much weight before the grip and balance feel secure. Master the unusual grip with light weight before progressing.
  • Rushing through reps. A controlled tempo helps maintain both the grip and proper form throughout.
