How to do it
- Stand tall with a dumbbell in one hand at your side and the other hand resting on your hip.
- Set your feet shoulder-width apart with knees soft and core lightly braced.
- Start with the working arm fully extended and palm facing your thigh.
- Curl the dumbbell up toward your shoulder, rotating your palm to face up as the elbow bends.
- Squeeze the biceps hard at the top with the elbow tucked beside your ribs.
- Lower the dumbbell slowly back down to full extension, then repeat for reps before switching arms.
Common mistakes
- Swinging the torso back to throw the dumbbell up, which turns the curl into a body swing.
- Letting the elbow drift forward, which shortens the biceps stretch and turns the lift into a partial.
- Cutting the bottom range short and not fully extending the arm, which kills the stretch position.
- Rushing the lowering phase, where most of the muscle-building tension actually lives.
