Smith Machine Bench Press

Anton YefanovUpdated September 6, 2026

The Smith machine bench press keeps the bar on guided rails, so the lifter presses a fixed path instead of stabilizing a free bar. The pectoralis major remains the prime mover with the triceps and front deltoid assisting. Direct comparison shows the trade-off: pectoral and anterior deltoid activation were comparable to a free weight bench press, but the medial deltoid worked harder on free weights.

A grip wider than shoulder width keeps emphasis on the chest instead of the front of the shoulder, and the bar should stop just above the chest rather than resting on it.

How to do the Smith Machine Bench Press

Position a flat bench under the Smith machine bar and load the desired weight.
Lie back so the bar tracks over your mid-chest and plant your feet on the floor.
Grip the bar wider than shoulder width and set your shoulder blades into the bench.
Rotate and lift the bar to disengage it from the safety hooks.
Lower the bar under control until it sits about an inch above your chest, then pause.
Press it back up without locking the elbows hard, and repeat for the prescribed reps.

Secondary:: Triceps and Shoulders

Why train it

Fixed bar path lets a lifter train chest pressing close to failure without a spotter.
Built-in hooks give a bail-out point at almost any height in the range.
Removes most of the balance demand, so attention goes to bar position and tempo.

Common mistakes

Using a narrow grip on the fixed track shifts the load onto the front deltoids instead of the chest.
Lying too far up or down the bench forces the fixed bar path to a point your shoulders cannot press safely.
Bouncing the bar off the chest replaces controlled work with momentum and jars the shoulder joint.
Forgetting to rotate the bar back into the hooks before sitting up leaves the load unsupported.
