Dumbbell skull crusher: how to do it with good form

The dumbbell skull crusher isolates the triceps and is kinder to the elbows than the barbell version.

How to do it

  1. 1

    Lie on a bench with a dumbbell in each hand, arms straight above your chest, palms facing each other.

  2. 2

    Keep your upper arms still.

  3. 3

    Bend your elbows and lower the dumbbells towards the sides of your head.

  4. 4

    Extend your arms until they are straight again.

Common mistakes

  • Upper arms swinging back and forth.
  • Elbows flaring out.
  • Weight so heavy the movement turns into a press.
