Versions and variations of the shoulder press are presented by Aaron Marino of alpha m.

The first is the standing straight bar shoulder press. You can do front to chin and up or you can take it behind the neck (those without shoulder problems). Make sure your knees have a nice bend in them.

The second version is seated in a Smith Machine, which the benefit is less pressure on the lower back. Adjust the position to the seat if you are going to the front or the back. You can also use dumbbells with knees slightly bent and soft. Next is seated dumbbell press. You want to keep it 90 degrees. Your shoulder has 3 different muscles (front, mid, and rear), and it’s important to focus on all three.
