Wolff's Law

We’ve known for over 100 years that Osteogenic Loading works. In the late 1800’s, Dr. Julius Wolff discovered that bones will adapt to the loads under which they are placed (Wolff’s Law). What we didn’t know until the 2012 Deere & Tobias study (to the right) was that there is a minimum threshold to triggering osteogenesis. 4.2 multiples of your body weight is the minimum required force to trigger bone growth in the hip joint (the most important place to avoid fracture) and peak forces with adults in conventional resistance exercise only show 1.26 to 1.54 multiples of body weight.
