The structural base of the spine contains three bones – sacrum, and two ilium – for a total of three joints.

The goal of pelvic floor exercises is to maintain the quality of these three joints.  The functional basement is the pelvic floor. Exercise programs for this are might  include awareness of the pelvis and pelvic floor, reinforcement of the pelvis, sub-umbilical ABS and ELDOA of the Sacro-Iliac Joint (SIJ).
