Narrow-Stance Barbell Squat
Quads, Glutes


Legs / Beginner / Compound (multi-joint)
A back squat with the bar guided by a Smith machine, building the quads and glutes.
Loads the knee. Use a load you can control and skip it if it causes pain.
Why it hurts: The fixed bar path forces the knees far forward and the lower back to bend to keep up.
✓ Instead: Place the feet slightly in front of the bar and find the position where the shins and back stay comfortable.
Why it hurts: The rails stop the bar falling, not the knees and back taking a load they are not used to.
✓ Instead: Load it like a free squat and set the safety stops just below your lowest point.
