A wonderful way to exercise if you have back pain issues. You only have to do it a few minutes a day. I use mine several times a day for two to five minutes at a time.
If you wonder what I get all excited about in the middle of this video, it is that the UPS man walked up to my OPEN front door and saw me through the storm door jumping on my bottom.
Note: Very important to buy a QUALITY trampoline for this. I have another trampoline I paid about $45 for, and it is like jumping on cement. This is a Celluciser. Here is a link showing the guy who owns the company doing this exercise CORRECTLY. I'll take another video if I EVER can bounce from cheek-to-cheek -- WOW!!!!
