In just 10 minutes, once a week, people can build bone density and muscle strength. OsteoStrong isn’t a prescription, gym membership or diet. Members experience a precise level of force, customized for their particular musculoskeletal system. Published clinical research data has shown that osteogenic loading sessions done once a week can increase bone density as much as 14 percent in as little as six months. There is not a contract; memberships are month-to-month.
