Barbell Side Squat
Quads, Glutes, Adductors


Legs / Intermediate / Compound (multi-joint)
A backward lunge with a barbell on the back, building the quads and glutes.
Loads the knee. Use a load you can control and skip it if it causes pain.
Why it hurts: A narrow base makes you wobble and lets the front knee collapse inward, straining the knee and hip.
✓ Instead: Step as if on train tracks, feet about hip-width apart side to side.
Why it hurts: The knee takes rotational load and the patellar tendon is overloaded.
✓ Instead: Keep the front foot flat and the knee tracking over the middle toes. Take a longer step if the heel lifts.
Why it hurts: Repeated impact bruises the kneecap and irritates the knee joint.
✓ Instead: Lower under control until the back knee hovers just above the floor.
