This exercise is the same as conventional or back squats, but your legs are widely spread wider with your toes pointed outward. Doing so specifically works the inner thigh.
1. Place the bar atop your shoulders, spread your feet wide (pointing your toes in the same direction as your knees).
2. Inhale and lower your body until your thighs are approximately parallel to the floor.
3. Stand and return to starting position, exhaling at the top of the movement. Repeat the next repetition.
Notes: The primary muscles involved in this exercise are the quadriceps, all adductors (adductor longus, adductor magnus, adductor brevis, pectineus and gracilis), the gluteals, the hamstring group, and the sacrospinalis muscles.
