The strict press is a huge developer of the deltoid muscles. The anterior deltoid puts in work. As you get more proficient at the movement, and your body begins to coordinate more and more muscles, you’ll feel that lateral deltoid and that rear delt firing as well.
Being a pressing movement, you will also feel your triceps doing a bunch of work. Where the deltoids help get the barbell off your chest, the triceps are what help you lockout the movement. No matter the pressing the movement, don’t ever discount the triceps contribution to making the weight move.
