Every woman wants round, tight glutes. And while the Butt Blaster is a great way to build them up, squatting may be an even better way. But not just any kind of squat. The best way to squat to focus on the glutes is to take a very wide stance. Italian researchers found that when subjects moved from a hip-width stance to a stance about double hip width, muscle activity of the glutes increased by more than 40%. So to really build rock-hard round glutes, start with wide-stance squats while your body is strongest, and save the Butt Blaster for later in the workout.
