  3. 3Plant your feet, pull your shoulder blades back and down, and keep a slight upper-back arch.

Execution

  2. 2Keep forearms vertical and wrists stacked over your elbows.
  3. 3Pause briefly at a comfortable stretch without letting your shoulders roll forward.

Key form cues

  • Forearms vertical
  • Shoulders down and back
  • Stretch, then squeeze
  • Press up and in

Common mistakes

  • Elbows flared straight out at 90°

    Tuck them to roughly 45–60° so the dumbbells travel beside the mid-chest.

  • Going so deep the shoulders roll forward

    Stop at the deepest point where your shoulder blades stay pinned to the bench.

  • Dropping the dumbbells out to the sides after the set

    Bring them back to your chest, tuck your knees and rock up to sitting with control.

Range of motion

From dumbbells beside the mid-chest at a comfortable stretch to arms extended over the shoulders.
