The single-leg squat -- also known as the pistol squat -- is one of the best ways to train your lower body . Unfortunately, it's also one of the most difficult moves to perform. The exercise requires an extreme amount of strength, flexibility, and balance, which is why you don't see many guys cranking out rep after rep at the gym. But there's a simple solution to mastering the move: the lateral pistol squat. "It's basically a deep side lunge that helps you build the leg strength and ankle, hip, and groin mobility needed to work your way up to a true pistol squat," says BJ Gaddour, C.S.C.S., creator of 10-Minute Torchers. Add this move to your workout routine and get on the fast track to conquering one of the greatest lower-body exercises of all time.
