Has anyone tried the Urban Rebounder? I am considering purchasing one because it advertises that does not affect your joints. I have arthritis and bone spurs. In fact, my orthopedic doctor told me I have the knee of a 70 year old. That's twice my age! Anyway, running is no longer an option, but I want something that will work quickly - It claims to burn 569 calories on an average sized person - so I figure I should burn that in half the time!!! –

Any info will be greatly appreciated!!!

The Urban rebounder I'm talking about is the one this MSN Fitness aabout. I read about it here:

4 Fun Ways to Fight Fat - MSN Health & Fitness - Fitness

and on its own site:

Urban Rebounding program is a fun workout for all ages, shapes, and sizes.

...and there is actually a big difference (a good difference, actually) between it and the normal mini tramp that you can get at Dick's or Target or someplace else like that. There are more springs and the whole thing seems more 'heavy duty' than the average type. I compared mine side by side when I got the Urban Rebounder and there definitely is a difference.

One of the other things I like about the Urban Rebounder is the fact that it comes with a handrail (it can be detached depending on which routines you are doing). I think it is actually designed for the senior workout, but it is great for anyone -- especially if you are a bit on the klutzy side like I am or if you are still pretty out of shape. I actually use it for a lot of the workouts and just modify them to compensate for the handrail, as needed.

Last, but not least, it does come with a lot of different workouts on the CDs. I'm not fit enough to do some of them yet...but they are things that I can strive toward as I get more fit.

I have horrible knees and have had knee surgery on one of them and I don't hurt when I use the Urban Rebounder.

I bought mine from the infomercial and paid full price. It's expensive when compared with the department store variety of mini-tramp, so I would try to see if maybe you can find it on Amazon or at half.com or somewhere like that to see if you can get it a little cheaper.
