Curtsy lunges are a great alternative to the traditional lunge that targets the inner thigh muscles.
The lateral lunge is one of the most effective exercises in targeting the adductor muscles of the inner thighs.

This exercise requires a band but is one of the best movements to give you a nice burn at the underbutt.
