Serratus Anterior
Serratus Anterior is a cool little muscle group that packs a lot of punch for its size. It looks really wicked from the front and sides.
This muscle group is responsible for shoulder protraction and scapula rotation. Train it with small movements. One option is the High Plank Press:
To do High Plank Press, start in the high plank position. Relax so that your shoulder blades come together. Now, press down hard. You will only move a few inches, but this will work Serratus Anterior.
You can do this motion in another way:
Work the Serratus Anterior while you're doing Bench Press by really giving an extra strong push at the top of the lift. Maybe even pulse it for a couple reps at the top. Again, this will be a very small movement.
