Equipment
How to do it
- Stand with your feet shoulder-width apart and the bar resting on your upper chest.
- Grip the bar with a pronated grip, hands slightly wider than your shoulders.
- Brace your abs and glutes to stabilize your torso before pressing.
- Press the bar straight up, moving your head slightly back out of the way.
- Extend your elbows overhead and bring your head through to finish with the bar over your neck.
- Lower the bar under control to your upper chest.
Common mistakes
- Over-arching the lower back while pressing
- Pressing the bar forward instead of straight up
- Failing to bring the head through at the top
What the evidence says
Across four shoulder press versions, standing with dumbbells produced the highest deltoid activation and was also the version allowing the lowest 1RM. That's a trade-off, not a ranking: pick stability and activation, or load.

Comparing free barbell against machine in eight competitive bodybuilders, the barbell version excited the shoulder muscles more than the machine, which stabilises the path for you. The machine isn't worse, but don't expect it to replace the barbell's stabilisation demand.

Measuring four exercises in the same group, the shoulder press produced the highest anterior deltoid activation (33.3% of maximum contraction) and hit the medial deltoid almost as hard as the lateral raise (27.9% vs 30.3%), while the bench press barely reached 5%. Horizontal pressing doesn't cover the shoulder; overhead pressing gets much closer.

What isn't settled: All three claims come from acute measurements — electrical activation and load lifted in one session — not from growth. We found no long-term training study comparing seated vs standing, barbell vs dumbbell, or machine vs free weight for shoulder hypertrophy. More activation is not more muscle: it's a reasonable hypothesis, unconfirmed. There is no specific literature on the Arnold press or the Smith machine version.
