I have not seen Bodylastics before. I like low-tech, low-overhead equipment, and it looks like Bodylastics fits the bill. The muscle man carrying tires on the website gives me an idea, though--I think I'll get a tire and use it for resistance work in my yard. Free and effective!

I do Pilates at home, including working with a magic circle (a pilates thing) and the 100 pushups regimen, although I'm not all that consistent with the pushups.

Feel better soon!
