I just finished editing and posting The Buttocks, an important ATM lesson in my Integrating the Legs series that follows up on and relates learning from the Activating the Arches lesson to the most powerful muscles of the body.
Finishing up adding bumpers to the old lessons too.
In the end almost all these initial eleven lessons are newly recorded this spring, except for three from when this project was born way back in 2012: Activating the Arches, Your Navigational Pelvis, and The Anti-Gravity Lesson.
