Dumbbell Waiter Biceps Curl

Setup

1. 01Stand tall with feet hip width apart holding one dumbbell vertically.
2. 02Place both palms flat under the top plate, fingers pointing up around the handle.
3. 03Let the dumbbell hang at arms length in front of the thighs.
4. 04Pull the shoulders back and brace the trunk before the first rep.

Execution

1. 01Curl the dumbbell up while keeping the top plate facing the ceiling the whole way.
2. 02Keep elbows pinned close to the ribs as the weight rises.
3. 03Squeeze hard at the top with the dumbbell near chin height.
4. 04Lower under control until the elbows are fully extended.

Checkpoints

• -The top plate stays level like a tray through the whole rep.
• -Elbows stay in front of the ribs, not drifting behind the torso.
• -Wrists stay flat under the plate rather than bending back.
• -Torso stays upright with no backward lean.

Common mistakes

• -Letting the dumbbell tilt forward at the top, which kills the supination bias.
• -Swinging the hips to start the rep.
• -Flaring the elbows out to shorten the range.
• -Rushing the lowering phase.
