How to Do the Smith Bench Press

Follow these steps to perform the Smith Bench Press with correct form:

1Adjust the height of the smith machine bar to chest level.
2Lie flat on the bench with your feet firmly planted on the ground.
3Grip the bar with an overhand grip slightly wider than shoulder-width apart.
4Unrack the bar and lower it towards your chest, keeping your elbows tucked in.
5Pause for a moment when the bar touches your chest.
6Push the bar back up to the starting position, fully extending your arms.
7Repeat for the desired number of repetitions.

Muscles & Anatomy

The Smith machine bench press uses a fixed, guided barbell on vertical (or slightly angled) rails to perform a pressing movement targeting the pectorals, anterior deltoids, and triceps. The guided bar path eliminates the stabilization demand that a free barbell requires — the shoulder, rotator cuff, and scapular stabilizers that work during a free barbell bench press are largely removed from the equation on the Smith machine. This allows greater load to be placed on the chest and triceps because they don't have to share neural resources with the stabilizing muscles. The Smith machine also allows the lifter to change hand position, press angle, and torso positioning to shift emphasis across different portions of the pectorals more easily than a free barbell, and the safety catch system allows training to failure without a spotter.

Pro Tips for Better Results

1Use a slight forward grip position rather than directly under the bar path. Because the Smith machine's fixed bar path doesn't account for the natural arc of a barbell bench press, gripping directly beneath the starting position can push the bar into an unnatural vertical trajectory. Position the bench so the bar makes contact with the lower chest at the bottom, not the clavicle.
2Flare the elbows at approximately 60–75 degrees from the torso — not 90 degrees (elbows straight out) and not tucked tightly to the sides. The fixed bar path of the Smith machine makes elbow angle especially important because the chest, shoulder, and tricep load distribution is set by this angle and cannot be adjusted during the lift.
3Use the safety catches to train to failure safely. One of the Smith machine's primary advantages is the ability to rack the bar at any point in the movement. Set the safeties 2–3 inches below the lowest point of your press so you can safely fail without being pinned under the bar.

Common Mistakes to Avoid

✗ Setting the bench position so the bar path is directly vertical over the lower chest

Fix: Many trainees set up for Smith bench press as they would a barbell bench press, but the vertical bar path means the trajectory is fundamentally different. Adjust the bench so that at the bottom, the bar rests on the lower pectorals with forearms vertical. This requires the bench to be positioned slightly differently than for a free barbell.

✗ Using the Smith machine as a substitute for learning free barbell technique

Fix: While the Smith machine is a valid training tool, using it exclusively prevents development of the stabilizing muscles required for free barbell bench pressing. Use the Smith machine for specific goals — training to failure without a spotter, emphasizing pec isolation, or when injury requires reduced stabilizer demands — but develop free barbell technique in parallel.

✗ Bouncing the bar off the chest

Fix: The fixed bar path and often-heavier loading on the Smith machine make bar bouncing off the sternum a common injury mechanism. Lower the bar under control to a light touch on the lower chest and press from a dead stop. Never use the chest as a spring board — the fixed path removes the natural ability to adjust bar position mid-rep.

✗ Overarching the lower back excessively

Fix: Some arch is acceptable and standard in bench pressing — it protects the shoulder and increases pectoral range. Extreme arch that lifts the hips off the bench is a powerlifting technique that is both less effective for hypertrophy and potentially stressful to the lumbar spine under heavy Smith machine loads. Keep glutes in contact with the bench.

How to Program the Smith Bench Press

Sets & Reps

3–5 sets of 6–12 reps. The Smith machine bench press works across the full rep range from strength (4–6 reps heavy) to hypertrophy (8–12 reps) to metabolic (15–20 reps). Its greatest utility is at the higher rep end — training to failure safely — and at moderate loads where the pectorals can be trained with maximum isolation from the stabilizing demand.

Frequency

2 times per week on push or chest days. The Smith bench press can replace or supplement free barbell bench pressing. It works best as a supplemental tool after heavy free barbell pressing to add safe-to-failure volume, or as a primary pressing tool when recovering from shoulder injuries that are aggravated by free barbell stabilization demands.

Where to Place It in Your Workout

Use after free barbell bench pressing as a secondary pressing movement, or as the primary chest exercise on hypertrophy-focused days. It is particularly effective as a drop set or rest-pause tool at the end of a chest session because the safety catches remove the need for a spotter during high-fatigue failure sets.

How to Progress

Progress identically to free barbell bench pressing — add 2.5 kg per week when hitting the top of the rep range with full range of motion across all sets. Track Smith machine progress separately from free barbell progress because the two exercises have different strength baselines due to the removed stabilizer demand. Both will improve independently.

Variations & Alternatives

Free Barbell Bench Press

The standard free barbell version that requires full shoulder stabilizer activation. Develops the stabilizing musculature that the Smith machine doesn't train. The most transferable pressing strength builder for sport and real-world activities. The complementary exercise to the Smith machine bench press for complete chest development.

Smith Machine Incline Bench Press

Set the bench to 30–45 degrees and perform the press on the Smith machine. Shifts emphasis to the upper pectorals and anterior deltoids. The incline on the Smith machine has the same bar-path considerations as flat — ensure the bar descends to the upper chest with forearms vertical at the bottom.

Smith Machine Close-Grip Bench Press

Hands positioned inside shoulder width on the Smith bar. Shifts emphasis from the pectorals to the triceps and reduces the range of motion for the chest. A useful triceps building variation that benefits from the Smith machine's fixed path, which makes the close-grip press easier to execute than with a free barbell.
