How to do it

Stand with dumbbells at your sides, palms facing your body. Curl the weights up towards your shoulders, keeping your palms facing each other throughout the movement. Lower back down with control.

  1. 1Hold the dumbbells with a neutral grip and curl them by bending your elbows, feeling your brachialis and biceps work
  2. 2Keep your elbows tucked at your sides and your wrists in a neutral position
  3. 3Squeeze at the top and lower slowly to emphasise the eccentric phase

Common mistakes

  • Don't swing the dumbbells or lean backward to lift them
  • Avoid rotating your wrists or letting your elbows drift forward
  • Don't rush; maintain a controlled pace for both upward and downward movements
