Step-by-step

  1. Set the bench at a 15 to 30 degree decline, secure your feet under the pad, and position your eyes directly under the bar before unracking.
  2. Grip the bar just outside shoulder width, unrack by rotating your wrists, and lower the bar under control to the lower portion of your chest.
  3. Keep your shoulder blades pinched together and your lower back lightly arched as the bar touches your chest without bouncing.
  4. Drive the bar back up in a straight vertical path, exhaling forcefully as you lock out and squeeze the lower chest at the top.

Common mistakes

  • Flaring the elbows to 90 degrees which stresses the shoulder joint — keep elbows at roughly 45 to 75 degrees to your torso throughout the press.
  • Letting the bar crash onto the chest — control the descent with a 2 to 3 second lower to protect your joints and keep tension on the muscle.
  • Setting the decline too steep which shifts load away from the chest onto the front delts — stick to a moderate 15 to 30 degree angle for optimal lower chest targeting.

Pro tip — At the top of each rep, think about pressing the bar apart horizontally as if you are trying to bend it outward — this cue increases pectoral fiber recruitment without changing your actual grip and is something most beginners never learn to feel.
