How to do it

  1. Stand tall with a dumbbell in one hand at your side and the other hand resting on your hip.
  2. Set your feet shoulder-width apart with knees soft and core lightly braced.
  3. Start with the working arm fully extended and palm facing your thigh.
  4. Curl the dumbbell up toward your shoulder, rotating your palm to face up as the elbow bends.
  5. Squeeze the biceps hard at the top with the elbow tucked beside your ribs.
  6. 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.
