Machine Presses

Machine presses train front and side deltoids.  Doing Presses on a machine helps makes the movement very strict.  Another plus here is you can allow the weight to come down much lower, giving an extra Stretch in your front delts.  There are a variety of shoulder press machines, but They all work the same.

Implementation: (A)  Hold the handles of the machine at shoulder height and (B) drive up till your arms are locked out, Then let the weight down under control to the starting position, getting a maximum stretch at the bottom. You can also Use machines Behind the neck presses.
