Barbell Side Squat
Quads, Glutes, Adductors


Legs / Advanced / Compound (multi-joint)
A split squat with the rear foot on a bench and a barbell on the back, building the quads and glutes one leg at a time.
Loads the knee. Use a load you can control and skip it if it causes pain.
Why it hurts: The rear hip flexor is over-stretched and the lower back arches, pulling on the lumbar spine.
✓ Instead: Use a knee-height bench, rest the laces of the back foot on it and find a stance where the front shin stays roughly vertical at the bottom.
Why it hurts: The back knee and hip flexor take load they are not in a position to handle, and the front leg gets little work.
✓ Instead: Keep about 80% of your weight on the front foot; the back leg is only for balance.
