what muscle group does the bench press work
The bench press is a compound push exercise that activates a number of upper-body muscle groups. These groups include the pectorals, deltoids, triceps, biceps, trapezius and core muscles. You can shift the emphasis of the press to specific muscle groups in that span by widening or narrowing your grip on the bar, by replacing a barbell with dumbbells, or by performing the press on an inclined or declined bench.
