Katy Perry looks amazing in her various bikinis . What’s her secret? According to a recent interview with Cosmo , her favorite way to exercise is jumping rope . Not only does it burn calories - 295 per 30 minutes - but jumping rope also helps build bone-mineral density and makes your body stronger. It’s a simple and inexpensive way to get your heart rate up; use it as

your main form of cardio or to warm up before strength training. Katy even jumps rope as a warmup before shows. Since this little gadget is so portable, you can pack it in your gym bag, suitcase, car, and even your purse and always have a way to get in a good workout.
