When guys who work out regularly do a flat bench press with a normal weight, their chest and front shoulder muscles are working just as hard as each other.

Effect of Five Bench Inclinations on the Electromyographic Activity of the Pectoralis Major, Anterior Deltoid, and Triceps Brachii during the Bench Press Exercise

Cross-Sectional Study

Human

2020 Oct 8

The study looked at muscle activity during flat bench presses in trained men and found that the chest and front shoulder muscles are equally active, just like the claim says.

Similar Assertions

When guys who lift weights do the incline bench press, the steeper the angle, the more their front shoulder muscles work — especially at 60 degrees, where it's working the hardest.

When bodybuilders lower the bar behind their head during a military press, their front and rear shoulder muscles work harder than when they do the same move in front of their head.

When you do bench presses on a flat bench vs. a slightly angled one, different parts of your chest muscle get worked more — the lower chest works harder on a flat bench, while the upper chest works harder when the bench is tilted up.

When bodybuilders do overhead shoulder presses with the bar behind their head, their rear shoulder muscles work a lot harder than when they do the same move in front — at least according to this claim.

For competitive male bodybuilders, lowering the bar behind the head during shoulder presses seems to work the side of the shoulder muscle harder than pressing in front, based on muscle activity readings.
