The overhead press for shoulder and upper-body strength

Pressing a barbell overhead trains the entire shoulder girdle and core as a coordinated unit.

Why it works

The overhead press requires the shoulders, triceps, and upper chest to move the load while the trunk, glutes, and legs create a rigid platform. Because no bench support is available, the core must actively resist spinal extension under load — making this a compound movement that trains mid-section stability as a byproduct of upper-body pressing.

How to do it

1. Hold the bar at shoulder width, resting on the front delts, elbows slightly forward.
2. Press the bar in a vertical line, moving the head back slightly to clear the bar path, then back under it at the top.
3. Lock out the elbows and shrug the shoulders at the top to engage the upper traps and stabilize the load.
4. Lower the bar under control back to the starting position on the front delts.

Evidence

The overhead press is a standard compound pressing movement; its advantages over seated or machine pressing are primarily functional (core demand, shoulder stability). Strength transfer evidence is mechanistic rather than directly trialed. (mechanistic)

The overhead press places greater demand on thoracic mobility than other presses; individuals with limited shoulder mobility may require modification or initial work on mobility.

Common mistake

Pressing in front of the face rather than in a true vertical line — this increases the bar’s moment arm and reduces the load capacity significantly.
