This one is self-admittedly difficult. It is strange to try to connect the diaphragm to the movement of the pelvic floor, and yet when this function can be in its optimal state in our bodies we have a huge advantage in function, stamina, and efficiency. When this connection works as intended we move in ease, drain less energy, and just feel like movement happens with more ease. Don’t feel too frustrated if it doesn’t come easily at first, there may be some layers that need to be unraveled first, go back to some of the earlier inquiries. To set up for this one, you may need a heartbed type pose, raised higher at the head, foot soles together with knees opening onto bolsters or blocks for support. This raised position brings comfort to the body and good access for the minds eye to see the pelvic floor. Good Luck.
