Narrow-Stance Barbell Squat
Quads, Glutes


Legs / Advanced / Compound (multi-joint)
A barbell exercise for the quads, with the hip abductors, adductors and calves assisting.
Why it hurts: The spine is compressed between the bar and the box, a real risk for the lower back.
✓ Instead: Sit back under control, touch the box lightly, then drive up.
Why it hurts: Losing the brace mid-rep lets the spine round when you try to stand.
✓ Instead: Stay tight while seated: brace, keep the shins vertical and stand straight up.
