Can Jumping Rope Get You Ripped?

Some gyms are now focusing classes and even structuring their businesses aroung jump-roping, claiming that the benefits of jumping rope outweigh some traditional cardiovascular training methods.

Edward Jackowski, who also wrote the book "Jump Into Fitness," describes jumping rope as an intensive cardiovascular workout that has one-fifth the impact on the back and the knees as running and burns more calories in less time. "Jumping rope for 10 minutes at 150 turns per minute is equal to 30 minutes of running between six and seven miles per hour," he said.

Hold on: 150 turns per minute? Yeah, that's a lot more intense than the double-dutch you're likely to see during recess at the local elementary school. If you do the math, 150 turns per minute is two-and-a-half jumps per second.
