Sentences with phrase «number of muscles compared»

The main benefit of using dumbbells is that it requires you to engage a greater number of muscles compared to the barbell and machine variant and actually activates the lower fibers of the chest press better than a barbell press — since your hands are free to move across your body when you use dumbbells, the lower pecs get a better workout.
