Tired of basic squats and traditional jump squats? If you're ready for an next-level approach to working out your legs, as well as a way to build explosive strength and improve hip stability and rotational power, then try this advanced jump squat. Start in squat position, jump up as high as possible, and then rotate left to land facing the opposite way. Repeat, rotating right, for a total of 10 reps on each side (20 in all).
