Smith Machine Shoulder Press

The Smith machine shoulder press is an overhead press on a bar that runs along fixed vertical rails, usually done seated on an upright bench. It works the front and side shoulders and the triceps, and because the machine balances the bar you can press heavy, repeatable sets with little skill demand.

How to do it

Step by step

Set an upright bench (about 80–90°) inside the Smith machine so the bar travels down just in front of your face and reaches chin to upper-chest height. Set the safety catches at that bottom height.
Sit with your back and head against the pad and your feet flat on the floor, a little wider than hip-width.
Take an overhand grip slightly wider than shoulder width so your forearms are vertical when the bar is at the bottom. Keep your wrists stacked over your forearms.
Brace your trunk, then rotate the bar hooks off and hold the bar at the top with straight arms.
Bring the bar down under control until it is level with your chin or upper chest, elbows slightly in front of the bar.
Press the bar straight up the rails until your elbows are straight, keeping your back and head on the pad.
Breathe at the top if you need to and re-brace before the next rep.
After the last rep, lock out and rotate the bar back onto the nearest hooks.

Common faults

What goes wrong, and the fix

Bench set too far forward or back

Fix: Move the bench until the bar passes just in front of your face at the bottom.

Arching your back off the pad

Fix: Brace your trunk and keep your back flat against the pad for every rep.

Elbows flared straight out to the sides

Fix: Keep your elbows slightly in front of the bar and forearms vertical.

Half reps at the top

Fix: Bring the bar to chin or upper-chest height on every rep.

Wrists bent back

Fix: Grip the bar low in your palm with your knuckles pointing up.

Dropping the bar between reps

Fix: Take about two seconds to bring the bar down, then press.

What the research says

Muscle growth · first choiceStrengthRehab & prehabGeneral fitnessEndurance

Machine or free weight — A meta-analysis comparing free-weight and machine training found similar muscle growth, while strength gains were specific to the kind of equipment trained on.
Load and effort — Studies show muscle growth is similar across a wide range of loads when sets are hard, and training to true failure adds only a small extra benefit. The guided bar makes sets close to failure practical without a spotter.
Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns. Around 10 or more hard sets a week has been associated with more growth than fewer than 5.
Rest — In trained lifters, rests of about 3 minutes have produced greater strength and size gains than 1-minute rests.
Rep range — Many lifters use this press for sets of about 6–15 reps as a shoulder builder after heavier free-weight pressing.
