Squeeze your shoulder blades together gets repeated in nearly every posture and lifting cue, but for a lot of people that instruction overtightens the upper traps and rhomboids while leaving the actual weak link, the lower traps, doing almost nothing.

Why This Cue Became the Default

The origin: rounded shoulders being such a visible and common posture problem that a simple, single instruction, squeeze the blades, spread everywhere as the go-to fix, regardless of which muscles were actually underperforming.

Why It Often Recruits the Wrong Muscles

The mechanism: most people responding to ‘squeeze’ by hiking and tensing the upper traps near the neck, since those muscles are easier to consciously activate, while the lower traps that actually stabilize the shoulder blade against the ribcage stay passive.

What This Overtightening Actually Causes

The consequence: upper trap dominance from repeated squeezing cues contributing to neck tension and a shrugged, elevated shoulder position that looks like better posture but adds strain rather than resolving it.

What Cue Works Better Instead

The fix: replacing ‘squeeze’ with ‘draw the shoulder blades down and back,’ which specifically targets the lower traps, combined with rows performed slowly enough to feel the bottom of the shoulder blade engage, and the frame (squeeze cues overactivate the upper traps while leaving the lower traps idle — cueing a down-and-back draw instead is what actually corrects the posture the squeeze cue was meant to fix.)
