You know I’m big on waking up and falling asleep lately, but I can say that it helps me to encourage forward and back between the hamstrings and quads for stretch in the ilio-tibial band, and stretch in the ilio-tibial band can cause the sartorius and gluteus to turn the pelvis. About then I think, well, really all this action can be generated by the sacrum, and where’s the forward and back and side-to-side at the sacrum?
And a dollar eighty, gets a cup of coffee.
