Guillotine Press (Barbell)

A barbell bench press variation where the weight is lowered to the neck rather than the chest to maximize pectoral stretch. This wide-grip movement isolates the upper chest while reducing front deltoid involvement.

How Iridium Programs This

Given the high stress this movement places on the shoulder capsule, Iridium analyzes your 7-day history and sub-muscle fatigue levels to ensure your anterior delts are sufficiently recovered before programming it.

Form Cues

Do
  • Take a grip significantly wider than shoulder-width
  • Flare your elbows out to the sides at a 90-degree angle
  • Lower the bar slowly and directly toward your neck
  • Keep your feet flat on the ground for stability
  • Squeeze your chest muscles hard at the top of the movement
Don't
  • Don't bounce the bar off your neck
  • Don't tuck your elbows towards your torso
  • Don't arch your lower back excessively
  • Don't lift your head off the bench
  • Don't perform this exercise without safety pins or a spotter

Common Mistakes

  • Lowering the bar to the nipple line instead of the neck
  • Using a grip that is too narrow
  • Loading the bar with excessive weight
  • Flaring ribs too much
  • Losing control of the descent speed

Muscles Worked

This exercise is a highly specific isolation movement for the clavicular head of the pectoralis major (upper chest). By flaring the elbows and lowering the bar to the neck, the movement takes the anterior deltoids out of the equation and places a tremendous stretch on the outer and upper pectoral fibers.
