Hi Mello!
I've seen the exact red rags Cathe uses in her gym sold at Costco in bulk. They're great for lots of things, not just slidin' and glidin' on a wood exercise floor.
Low Intensity--YESSSS!!
Considering I'm just coming off of a bad bout with a mean upper respiratory virus, this suggestion is coming at a time when I'm all for some kinder, gentler workouts. Not to forget that my body is fast approaching the end of the fifties and the sixties are glaring at me...
