The very specific bioDensity exercises (the heart of the program) create a trigger event in the body. A cascade of biological adaptations is set in motion. Studies have determined the average time needed to make these adaptations (break down old tissue and remodel new) is 5 -10 days. More frequent sessions on the bioDensity machine would be counterproductive interrupting the remodeling processes. The other technologies are not limited in frequency of use.
