Rebounding can have a couple of different meanings. While my mind goes immediately to basketball, someone else might think about the date she had after her last break up. But, neither of those things are what this post is about.

Rebounding, or jumping on a mini trampoline (rebounder), is one of the hottest ways to get in great shape. It's super beneficial -- a NASA study found rebounding to be 68 percent more oxygen-efficient than other types of cardio exercise, including running. Plus, you know, bouncing around is fun.

Perhaps even more important is the fact that rebounding has zero impact, but gives you high-impact results. And, you can do it in a class (such as Urban Rebounding), or you can do it at home with your own Urban Rebounder Folding Trampoline Workout System.
