Hi @novabill and @johnbishop I bought a Whole Body Vibration (WBV) Exerciser primarily to increase bone density. I wasn't thinking of toning muscles, but that has been one of the benefits. WBV also reportedly supports lymphatic drainage. I've been using it since August for 15 minutes, at least, 6 x a week, sometimes twice. Amazon has a large number of WBV machines. I chose Eilison Bolt because of its weight (11 lbs.), five year warranty, and it can be used on carpets (I put it on a yoga mat). It also has nine different programs reportedly with specific benefits. Make sure you read the disclaimers because people with certain health conditions should not use them. I had a mitral valve repair with a ring around the valve. My surgeon said the vibration machine would have no effect on it whatsoever. I'm glad I got one, regardless it will take a while to know the effect on my bone density.
