Karen, if someone has knee pain then the best position is sitting, placing their hands on their lateral/posterior rib cage and feel the breath into the hands rather than feeling on the inner thighs; or you could place a bolster under the pelvis in between the thighs and lower legs and have them sit on the bolster, then you would need to place something under their forehead, like a ball or another bolster to balance out the height of the pelvis. Hope this makes sense!
Madeline, thank you so much for this spinal warm up sequence :) I've taught it to my clients and they love it! They even asked me to write it down for their summer break so they can do it by themselves. I've told them it's yours.. A happy hug from Finland!
