This study attempts to prove that properly chosen yoga poses can reverse osteoporosis without having negative effects on the joints. In addition, we hope to establish a dose-response relationship between the quantity and quality of yoga, and rise in bone mineral density, and possibly bone quality.
Conventional medical wisdom puts people in an impossible position: exercise with impact, jogging, for example, is needed to stimulate the cells that build bone, but unfortunately, such exercise fairly reliably brings about arthritic joint destruction. No-impact exercise is harmless to the joints, but unfortunately, leaves the bones to slowly weaken even to the breaking point.
Therefore when it comes to bones, it is literally both ends against the middle. At the same time, it is universally acknowledged that not exercising at all tightens joints and ligaments, weakens muscles and bones alike, and is the worst of both worlds.
