Kettlebell swings torch calories, improve cardiovascular fitness, and build explosive strength. But if you want to reap even more benefits from the classic move, try changing up your stance.

“Staggering your feet activates more stabilizing muscles, which increases the intensity of the exercise and increases the challenge to your core,” says BJ Gaddour, C.S.C.S., creator of the Bodyweight Cardio Burners DVD.
