Participants do not have access to OSM. One Strong Mama is our program for pregnant people so it is very much a lay person perspective and does not go into depth with the "why" and does not provide a personalized approach. OSM teaches basics + addresses our full body 5 pillar body ready approach through exercise classes. It is a good one for pregnant people who do not need to teach it to others or understand the physiology, biomechanics, and the "why." We go way way beyond OSM in the BRM^® training.
