Sadly, the published research on this topic does not indicate that strengthen your bones through convention exercises or weight training is likely. A study published in 2012 identified that the minimum force required to trigger bone growth is 4.2 multiples of body weight (4.2 MOB). Engaging in that amount of force safely, outside of an OsteoStrong center is not recommended for most people. The good news is that our proprietary Spectrum System safely allows clients to experience much more than the 4.2 MOB minimum to trigger the skeletal building response people are looking for.
