How to Do a Shoulder Press: Form, Variations and Common Mistakes

The shoulder press is one of the simplest strength exercises there is — you push a weight from your shoulders to overhead — and one of the easiest to do badly. Done well, it builds strong, rounded shoulders and carries over to almost everything else you do in the gym. Done badly, it’s a common source of sore shoulders and lower backs.

Here’s how to get it right.

What it works

The shoulder press mainly trains your deltoids, especially the front and side portions, along with your triceps and the upper part of your chest. If you do it standing, your core and glutes work hard too, because they’re what keep you stable while the weight is overhead.

How to do a standing barbell press

1. Set up. Hold the bar at shoulder height, hands just outside shoulder width, wrists stacked over your elbows. Stand with feet about hip-width apart.
2. Brace. Squeeze your glutes and tighten your stomach as if you’re about to be poked in it. This stops your lower back from arching.
3. Press. Push the bar straight up, moving your head back slightly so the bar clears your chin. Once it passes your forehead, bring your head forward again so the bar ends over the middle of your foot.
4. Lock out. Finish with your arms straight and the bar directly over your head — not in front of it.
5. Lower with control. Bring it back to your shoulders the same way, without letting it drop.

Which variation to use

Almost every gym in Malaysia will have at least two of these:

• Seated dumbbell press. The best starting point for most beginners. The bench supports your back, and dumbbells let each arm move naturally, which is easier on the shoulders.
• Shoulder press machine. Good for learning the movement and for adding volume safely at the end of a session — the machine controls the path for you.
• Standing barbell press. The most demanding version, and the best for overall strength, because your whole body has to stabilise the weight.
• Arnold press. A dumbbell variation where you rotate your palms from facing you to facing forward as you press. It covers a bigger range of motion.
• Landmine press. Pressing one end of a barbell anchored in a corner. A good option if pressing straight overhead bothers your shoulders.

The mistakes to avoid

• Arching your lower back. The most common one. If you’re leaning back to finish the rep, the weight is too heavy — lighten it and brace harder.
• Flaring your elbows straight out to the sides. Keep them slightly in front of the bar; it’s kinder to your shoulder joints.
• Pressing the bar out in front. The bar should travel close to your face and finish overhead, not drift forward.
• Cutting the range short. Lower all the way to your shoulders and press to full lockout, unless an injury stops you.
• Going too heavy too soon. Shoulders are small muscles. Progress slowly.

How much and how often

For most people building strength and muscle, 3 to 4 sets of 6 to 12 reps, once or twice a week, is plenty. Rest a couple of minutes between heavy sets. Add weight only when you can finish every rep with good form.

If pressing overhead causes pain in the shoulder — not just muscle effort — stop and get it looked at by a physiotherapist before pushing on.

Most of these variations only need dumbbells, a bench and a barbell, so almost any gym will do. If you’re still looking for one, start with our gym listings by city.
