Dumbbell Skull Crusher

Starting position

  • Lie on a flat bench, dumbbells above the chest with straight arms.
  • Palms facing each other.

Execution

  • Lower the dumbbells beside the head by bending the elbows.
  • Extend back up; the upper arms stay still.
  • Breathe out as you extend.

Common mistakes

  • Elbows flaring wide.
  • Upper arms moving along.
  • Dumbbells too close to the face.
