TRICEPS

Dumbbell Skullcrusher

BeginnerDumbbell

A lying triceps isolation move using dumbbells instead of a bar. Working each arm with its own weight adds a bit of instability and stops your stronger side from taking over. A reliable pick for building triceps size and strength.

How to do it

  1. 1

    Lie back on a bench with your shoulder blades squeezed and feet planted flat beneath your knees.

  2. 2

    Keep your head, shoulders, and hips in contact with the bench.

  3. 3

    Hold the dumbbells above your shoulders, palms facing each other, elbows slightly bent.

  4. 4

    Brace your core and bend at the elbows to lower the dumbbells overhead, keeping your upper arms vertical.

  5. 5

    When the dumbbells reach just above your forehead, exhale and extend your arms back to the start.
