The Smith Seated Single Arm Neutral Grip Shoulders Press is a unilateral overhead pressing movement performed on a Smith machine with the palm facing inward toward your head. It targets the deltoids — particularly the lateral and anterior heads — with the triceps assisting at lockout. This exercise is well suited for building single-arm shoulder strength and correcting side-to-side imbalances.
How to do the Smith Seated Single Arm Neutral Grip Shoulders Press
- 1Set the Smith machine bar to approximately shoulder height when seated.
- 2Place an adjustable bench with back support inside or directly in front of the Smith machine, angled so one shoulder aligns with the bar.
- 3Set the bench back to an upright position (about 80–90 degrees) and sit down with your feet flat on the floor.
- 4Rotate the bar to unrack it, then grip it with one hand using a neutral grip — palm facing inward toward the center of your head.
- 5Brace your core, keep your back pressed into the bench, and hold your free hand on your thigh or your hip for stability.
- 6Press the bar straight up along the Smith machine track until your elbow is nearly fully extended without locking out hard.
- 7Lower the bar under control back to roughly jaw or upper-chest level, keeping your elbow at roughly a 45-degree angle from your torso.
- 8Complete all reps on one side, rotate the bar to re-rack, then reposition the bench and repeat on the other arm.
- 9Re-rack the bar by rotating it onto the safety hooks after your final set.
Form tips
- Keep your wrist stacked directly over your elbow throughout the press — avoid letting the wrist bend backward under the load.
- Align the working shoulder directly under the bar before you unrack so the Smith machine's fixed path works with your joint, not against it.
- Brace your core and press your opposite hip and foot into stable contact points to prevent torso rotation during the press.
- Control the descent — use a 2-second lowering phase to build tension and reduce shoulder joint stress.
- Start lighter than you expect to need; single-arm pressing on a fixed track exposes shoulder weaknesses quickly.
Common mistakes
- Letting the torso rotate or lean away from the bar: this shifts the load off the deltoid and stresses the lower back, reducing shoulder development and risking injury.
- Pressing the bar directly overhead without aligning the shoulder under the bar first: the Smith machine's fixed vertical path will force the joint into an awkward angle, increasing impingement risk.
- Flaring the elbow out to 90 degrees: a wide elbow angle puts unnecessary stress on the shoulder capsule; keep the elbow closer to a 45-degree angle from the body.
- Using the free arm to push off the thigh for momentum: this turns the movement into a cheat press, reducing deltoid stimulus and masking strength imbalances.
- Locking out the elbow aggressively at the top: forceful hyperextension at lockout places sudden stress on the elbow joint; stop just short of full extension.
Frequently asked questions
What does 'neutral grip' mean on a Smith machine shoulder press?
A neutral grip means your palm faces inward — toward the midline of your body (your head or opposite shoulder) — rather than facing forward. On a Smith machine, you achieve this by gripping the bar so your knuckles point to the side and your thumb points toward the machine.
How is this different from a standard seated Smith machine shoulder press?
The standard version uses both hands with a pronated (overhand) grip. This variation uses one arm at a time with a neutral (palm-in) grip, which reduces shoulder impingement for some lifters and forces each side to work independently, making strength imbalances easier to identify and correct.
Which muscles does this exercise work?
The primary movers are the deltoids, especially the lateral and anterior heads. The triceps assist significantly during the press to extend the elbow. Because the movement is unilateral, the core and opposite-side stabilizers also work to prevent rotation.
How should I set up the bench relative to the Smith machine?
Position the bench so your working shoulder sits directly under the bar when you are seated upright. The bar should clear your head without you having to lean to one side. Adjust the bench forward or back until that alignment feels natural before you unrack.
Can I use this exercise to fix a shoulder strength imbalance?
Yes. Because each arm presses independently, the stronger side cannot compensate for the weaker one. Start with your weaker arm first each set, match the same weight and reps on the stronger arm, and over time the gap should close.
