Barbell Overhead Press

Stand with feet hip-width apart, bar resting on your front delts with a grip just outside shoulder width. Brace your core and press the bar straight overhead, moving your head slightly back to clear the bar path. Lock out at the top with the bar directly over your midfoot, then lower with control.

Pro Tips

• Squeeze your glutes and brace your core to prevent low-back arching
• Press the bar in a straight line — move your head, not the bar path
• Full lockout overhead with active shoulders at the top
• Start lighter than you think; this is the hardest main barbell lift to progress

Muscles worked

Primary: Anterior and lateral deltoid heads — the press drives the bar overhead through shoulder flexion (anterior deltoid) and abduction (lateral deltoid). The anterior head is the primary driver throughout the range; the lateral head becomes more active as the bar passes eye level.

Supporting: Triceps brachii (elbow extension at lockout), upper trapezius and serratus anterior (scapular upward rotation and stabilisation at lockout), core (resisting lumbar extension), glutes (posterior pelvic tilt cue to prevent lower back arch).

Common mistakes

Excessive lumbar arch: The most common form breakdown under heavy load. When the overhead press gets difficult, the instinct is to lean back and use the chest as a partial incline surface. This shifts the demand off the shoulders and compresses the lumbar spine. Brace the core and keep the ribs down.

Bar path deviation: The bar should travel in a straight vertical line. Any forward or backward deviation adds a horizontal moment arm and wastes force. Move your head back slightly to clear the chin, then move it forward again as the bar passes. The bar does not arc around your face — your face moves out of the bar’s path.

Not achieving full lockout: Stopping the press just short of full arm extension — a common practice to maintain tension — actually reduces shoulder strength development. Full lockout with actively elevated shoulders (shrug up slightly at the top) is the correct endpoint.

Losing tension between reps: Re-bracing at the bottom of each rep is essential. A lifter who takes a breath, performs a rep, breathes out, and attempts the next rep without re-bracing is pressing with a progressively less stable base.

Programming notes

The barbell overhead press is one of the canonical compound barbell lifts alongside the squat, bench, and deadlift. It is the primary upper body push movement in most linear programmes (5x5, Starting Strength), where it alternates with the bench press across training sessions. It is also the primary overhead movement in 5/3/1-family programmes.

Progress on the overhead press is the slowest of all main barbell lifts — 1.25–2.5 kg per session for beginners, and monthly increments for intermediate lifters. This is expected and reflects the smaller muscle mass being trained relative to the lower body lifts.

Frequently asked questions

Should I press from a rack or clean the bar from the floor?

Use a rack whenever one is available. Cleaning the bar from the floor to your front delts before each set adds unnecessary fatigue, increases injury risk under heavy loads, and limits the weight you can actually press. Set the bar at upper-chest height in the rack, unrack it to your front delts, then press. Reserve the clean only for situations where a rack is not accessible.

Why does my overhead press progress so slowly compared to my squat and bench?

The overhead press is limited by the smaller muscle mass of the shoulders and triceps relative to the lower body and chest. Beginners typically add 1.25–2.5 kg per session, far less than the squat or deadlift. This is normal and expected — do not inflate the weights by compensating with a layback or leg drive that turns it into a push press. Slow, honest progress on strict form builds the shoulder strength that carries over to every other upper-body lift.

What grip width should I use for the overhead press?

Your hands should be just outside shoulder width — roughly where the bar naturally sits on your front delts when you rack it. Too narrow and your elbows flare forward, reducing shoulder stability; too wide and your forearms angle inward, creating a less efficient pressing structure. A straight vertical forearm at the start position, with elbows slightly in front of the bar, is the correct reference point. Adjust from there based on your shoulder width and mobility.
