This we have an inventor, Dr. John Janquish. The best overview about him comes directly from his website: "Dr. John Jaquish began his experience in life sciences after being told by his Mother that she had been diagnosed with osteoporosis. John, in an effort to help his mother, created a device to place axial loading through bone to safely cause osteogenic loading events. The device was to trigger the effects of high-impact loading, but without the risk of injury." We also talk about another invention of his, the X3 bar, increasing force, strength through different ranges of motion, and more.
