Technique

  • Stand holding a dumbbell in each hand with your palms facing towards your body.
  • Lift one dumbbell in a slow and controlled manner by squeezing your biceps and keeping your elbows tucked in by your sides.
  • Keep your palms facing towards your body throughout, keeping the dumbbell in the “hammer” position.
  • Slowly lower the dumbbell until your arms are almost straight and then switch to the other arm – don’t fully straighten your arms and lock them out or you will release the tension on your biceps.
