I've been diagnosed with osteoporosis (I'm mid 40s) and am intending to use a power plate as part of my exercise regime as there appears to be evidence that if used correctly it's a good option for increasing bone density. I intend to try one in gym first, but if I get on OK I'll e looking to buy my own as it's not really practical to use the gym on an ongoing basis (the only one's around are quite a distance from where I live). There's a huge difference in cost between to original "power plate" and some of the cheaper one, and a number of comments online about the cheaper ones being inferior. However, some have quite good reviews. Has anyone got experience of some of the cheaper makes (and ideally can compare to a commercial power plate)? Thanks
