The machine shoulder press is a machine-based exercise targeting the deltoid muscles. It approximates the motion of a free-weight shoulder press, but uses a selectorized weight-stack or plate-loaded machine. Many such machines also allow you to choose between different grips and grip widths. Machine shoulder presses are often done for moderate to high reps, such as 8-12 reps per set or more, as part of the upper-body or shoulder-focused portion of a workout.
Builds size and strength in the deltoids
The machine allows for controlled reps and strict form
Load an appropriate weight onto the pins and adjust the seat for your height. The handles should be near the top of the shoulders at the beginning of the motion. Your chest and head should be up and handles held with a pronated grip. This will be your starting position.
Press the handles upward by extending through the elbow.
After a brief pause at the top, return the weight to just above the start position, keeping tension on the muscles by not returning the weight to the stops until the set is complete.
