The wide stance and outward foot rotation of the sumo squat variation preferentially emphasizes the inner thigh muscles (adductors), including the adductor longus, brevis, and magnus, along with the gracilis. Glutes (gluteus maximus, medius, and minimus) also play a significant role, contributing to hip extension and stabilization. Furthermore, the quadriceps (rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius) are engaged for knee extension. Supporting muscles include the hamstrings, calves, and core.
Developing these muscle groups offers several functional advantages. Enhanced hip stability and mobility contribute to improved athletic performance in activities requiring lateral movement, such as skating or cutting maneuvers. Stronger adductors can also reduce the risk of groin injuries. Incorporating this exercise variation can contribute to a well-rounded lower body training program, promoting balanced muscle development and overall leg strength.
