I have been very tempted to buy a piece of exercise equipment called The Fluidity Bar advertised on tv. Essentially a portable barre for doing certain methods of strength training, like Callanetics or Lotte Berke method.

Haven't though. It's not cheap, and I get the job done with my present equipment. Still, it does look interesting . . .

bought a cold solder device as a gift, upon request. not sure how it panned out.

lots of QVC & other home shopping stuff, most of it decent, but I don't think that's exactly what you're talking about.

the ab thingy that's basically a wheel with handles on either side does work well. But you can do the same thing with an exercise ball, which is far more versatile.
