The Shoulder Press Circular machine primarily focuses on two portions of the deltoids, also known as your shoulders, and it also works a lot of other muscles. Your trapezius, triceps and rotatory cuff muscles all have to work in conjunction with your shoulders for this exercise to be done.

The Deltoid Press by Panatta is a variation of the seated barbell shoulder press, used to strengthen the muscles of the shoulders. This machine is used to perform the pressing movement pattern with a focus on isolating the shoulders.
