Sumo squats are a variation of a regular squat, performed with a wider stance. Squats are great for working the large muscles of the thigh. Sumo squats also have the added benefit of particularly targeting the glutes and the inner thighs, which helps to tone and shape the legs and butt.1
The inner thigh muscles (adductors) function to bring the thighs together. However, they can be hard to train and tend to be weak in many people. Sumo squats strengthen this area, which can help with everyday activities and athletic movements such as moving from side to side (common in field and court-based sports).2
Variations: To make sumo squats harder you can add weight, such as dumbbells or a barbell.
