How to Execute the Barbell Flat Bench Press

Lie flat on bench with eyes directly under the racked bar, feet planted firmly into the floor. Grip the bar slightly wider than shoulder-width using a thumbs-around closed grip.

  • Primary Muscle: CHEST
  • Secondary Synergists: TRICEPS, FRONT-DELTS
  • Rest Interval: 120 seconds between sets

Step-by-Step Execution Guide

1

Lie flat on bench with eyes directly under the racked bar, feet planted firmly into the floor.

2

Grip the bar slightly wider than shoulder-width using a thumbs-around closed grip.

3

Retract your scapulae, pinch shoulder blades down and back, and unrack with straight arms.

4

Inhale and lower the bar under control to the mid-sternum, tucking elbows at roughly 45–60 degrees.

5

Touch chest lightly without bouncing, then drive feet into the floor and press bar up in a slight J-curve.

Common Mistakes & Form Fixes

Flaring elbows out at 90 degrees, stressing the anterior shoulder joint.

Bouncing the barbell off the ribcage using momentum rather than muscular control.

Lifting glutes off the bench to cheat the lockout.

Biomechanical Safety & Injury Warning

Always use safety spotter arms or a reliable spotter when lifting above 80% 1RM.
