Pressing a weight overhead will test the strength and stability of all three heads of your shoulder musculature, your shoulder girdle (the muscles surrounding your shoulder blades), and your core (both your abs and lower back) and, if you are performing standing variations, you will also train your glutes, quads and hamstrings to add stability to the lift.
Working Up To The Overhead Press
Overhead Press Form Guide
Stand with your body upright and core muscles braced, looking straight ahead. Hold the bar on your upper chest, gripping it with hands just wider than shoulder-width apart. Press the bar directly overhead. Don't tilt your hips forward during the move.
How To Perfect The Overhead Press
Take a shoulder-width grip
The wider apart your hands are on the bar, the weaker you will be and the less weight you will be able to lift. Aim for a grip with hands no wider than shoulder-width apart and keep your elbows directly underneath your wrists to keep you in the strongest mechanical position possible for the lift.
Mobile wrists are key
For the strongest press possible you need to have mobile wrists so that they can extend back towards your body,” says McKenzie. “The better the starting position of your wrists, the more able you are to initiate the move with a strong push. Better mobility will also allow your elbows to flare out slightly towards the sides as you press upwards.
Squeeze your shoulder blades
At the start of each rep focus on squeezing your shoulder blades together, then focus on using your shoulders to initiate the lift and get the bar moving. Lower the bar under control, ensuring that your shoulders are fully engaged and managing the weight with good form.
Adjust your head position
The bar starts across your upper chest below your chin, so your head must tilt backwards slightly as you push the bar up in the straightest line possible to avoid hitting your chin and nose. As you press the bar up, tilt your head backwards so that the bar just misses your nose on the way up.
Keep your chest up
You need to keep your chest up during each rep to maintain a strong and stable upper back, which in turn allows better and smoother movement patterns of all the muscles and joints involved in the lift – especially the shoulders, which are one of the most easily damaged joints in the body.
