About
An inner thigh squat (often called a sumo squat or wide-stance squat) primarily works:
Inner thighs (adductors) — the main muscle group emphasized because of the wide stance.
Glutes (buttocks) — especially as you push back up.
Quadriceps (front of thighs) — responsible for extending the knees.
Hamstrings (back of thighs) — assist with hip movement.
Core muscles — help stabilize your torso during the exercise.
