How to Execute the Flat Dumbbell Bench Press

Sit on flat bench with dumbbells on thighs; lie back bringing dumbbells to chest sides. Position feet firmly, retract scapulae, and hold dumbbells with a 45-degree wrist angle.

  • Primary Muscle: CHEST
  • Secondary Synergists: TRICEPS, FRONT-DELTS
  • Rest Interval: 90 seconds between sets

Step-by-Step Execution Guide

1

Sit on flat bench with dumbbells on thighs; lie back bringing dumbbells to chest sides.

2

Position feet firmly, retract scapulae, and hold dumbbells with a 45-degree wrist angle.

3

Press up smoothly until dumbbells converge above mid-chest.

4

Lower under strict control feeling a deep chest stretch at the bottom.

Common Mistakes & Form Fixes

Allowing dumbbells to drift over face rather than sternum.

Rushing the eccentric lowering phase.

Biomechanical Safety & Injury Warning

Keep wrist joints stacked directly over elbow joints.
