A good place to find more information on OsteoStrong is in Tony Robbins' book Life Force. Keep in mind the book is a sales pitch for Tony's new health organization. However, he claims to use OsteoStrong. While he gives no actual study information, which makes everything he says about it "conjecture", it might be worth a trip to the library to get the book. There are also other programs, research, products, and valuable info in the book. Worth a read. Being 65, healthy longevity is a big goal of mine.

Thank you to the person who mentioned NASA using vibration to restore bone density to astronauts spending extended time in space. That is fascinating and I will do more research on it. NASA is very public with their research and I've contacted NASA employees before on other NASA research projects and they were very forthcoming. If I find out anything useful, I will post it here and also on my blog.

I use a vibration plate at home. They are low cost and mine runs for a choice of ten or twenty minutes. If nothing else, it's a great warmup before a workout.
