Barbell Side Squat
Quads, Glutes, Adductors


Legs / Intermediate / Compound (multi-joint)
A Smith machine exercise for the quads, with the calves, glutes and hamstrings assisting.
Loads the knee. Use a load you can control and skip it if it causes pain.
Why it hurts: All body weight rests on one knee at end range, twisting it and loading the ligaments.
✓ Instead: Build up with box pistols to a height you control, keeping the knee over the middle toes.
Why it hurts: Weight shifts onto the forefoot and the knee takes the load.
✓ Instead: Hold a light counterweight in front of you, or put a small plate under the heel while ankle mobility improves.
