Technique guide

Set-up

  • Lie on a flat bench holding an EZ bar or dumbbells over your chest with straight arms.

How to do it

  1. Bend your elbows to lower the weight towards your forehead or just behind your head.
  2. Stop when your forearms are just past parallel to the floor.
  3. Straighten your arms to return to the start.

Coaching cues

  • Keep your upper arms still and angled slightly back.
  • Move slowly, especially on the way down.

Common mistakes

  • Letting the elbows flare out wide.
  • Lowering the weight too quickly.

Safety

  • Start light: the weight travels close to your head.
