Low-Incline Barbell Bench Press
Why it’s on the list: Many benches are fixed at a very steep angle, which requires a larger contribution from the front delts than the chest to move the weight. If possible, go for a less-steep incline to hit the upper pecs without as much stress on the delts. You can also easily do low-incline benches with an adjustable bench on the Smith machine.
If you’re really looking to build that shelf of an upper chest, EMG results have suggested that bringing your grip in a bit closer may hammer upper-chest fibers significantly more.
In your workout: Many chest workouts start with flat-bench movements first, then progress to inclines, but it’s time to get out of that bad habit. Every so often, start with inclines. The benefit is that you’ll be fresher and can lift more weight, which puts a greater amount of stress on the upper pec fibers and could lead to more growth.
