Technique
Setup
Take a very wide stance with toes pointed out slightly. Keep your feet planted throughout the set.
Movement
Shift your weight to one side, bending that knee and lowering your hips while keeping the other leg perfectly straight. Rotate the straight leg's toes toward the ceiling to allow for deeper range of motion.
Form Tip
Keep your heel on the floor for the working leg. Keep your chest up. Go as deep as your mobility allows. This is different from a side lunge because you do not step; you stay wide.
