I don't have a rebounder but we have a springless (Costco) trampoline and I work out on it 30 mins a day 6x per week. I vary my bounce depending on the beat of the music I listen to so sometimes it is a health bounce, sometimes I run laps on it (it's round, with a net to keep me from tumbling off) or do jumping jacks or skiing maneuvers. It is THE BEST overall toning workout if you ask me! just doesn't do much for the arms but works all the other core muscles like a gem!
