Jumping rope is a great cardio workout, the problem comes in when you are not very good at it, causing for many pauses in your workout until you can get your rhythm going again.
The makers of JumpSnap ($59.95) realized this frustration and created a rope less jump rope. Sounds like an oxymoron, I know, but the concept is a good one. The JumpSnap has two plastic handles with swinging plastic balls attached to the ends (very similar to the bichiballs I told you about before, just a little more high tech). The JumpSnap is unique in that the handles electronically count jumps, calories, time and other things to help you through your workout. The great part is that anyone with two feet can do it. The whole jumping over an imaginary rope thing does feel a little odd at first, but the snapping sound helps you maintain a rhythm while jumping so you can actually have fun while doing it!
