Couple questions:
1. Does the foundation series contain progressions for reaching the different splits for lower body; eg., front splits. side splits, etc? Or if not, does it contain progressions for preparatory work toward reaching these aspects of mobility?
2. Is there a series of progressions for the Natural Leg Curl? I ask because I see the single leg squat listed but no NLC. Is this because NLC is not considered "basic strength"? It's fine if it isn't covered because I am doing my own work with it but I do love this movement and it would be interesting to see what progressions there are for it.
