Narrow-Stance Barbell Squat
Quads, Glutes


Legs / Beginner / Compound (multi-joint)
A bodyweight exercise for the quads, with the glutes and hamstrings assisting.
Why it hurts: Even without weight, hundreds of reps on the toes irritate the kneecap and patellar tendon.
✓ Instead: Sit the hips back and down with the weight in the mid-foot, arms reaching forward for balance.
Why it hurts: The spine takes a jolt and you skip the controlled part of the squat.
✓ Instead: Lower slowly, tap the chair lightly and stand without rocking.
