Can't muster the motivation to make it to the gym? Skip it! Jumping rope burns more than 10 calories a minute while strengthening your legs, butt, shoulders, and arms. And it doesn't take long to reap major rewards. You can burn more than 200 calories in two 10-minute sessions each day (that's 1,000 calories a week)! Jumping rope is also a great way to fit in an effective cardio session when you're on the go—just toss your jump rope in your carry-on! You'll probably feel completely energized after jumping rope too.
