I used to have a friend who when I went over to his mother's house, she would constantly remind us that the furniture in the formal living room was, "Not for sitting!" (never mind that it always had that weird "Grandma" plastic on it and would have been uncomfortable as all get out...)
Little did I know that she was absolutely right, but was a bit off in her coordinates. It is not the furniture that is not for sitting, it is the Ischial Tuberosities that "are not for sitting!"
In the 'western world' (up until recently) we were the odd ones who would rest our Ischial Tuberosities (Butt) on objects in order to rest, eat, poop, converse with others, and travel. However, this is not what our Butts are primarily designed to do functionally. Our Butts are the source of large muscles that are useful and primarily for many other functions besides resting our weary soft bodies. Butts are great for standing, squatting, lunging, running, cracking walnuts (Joe D.), lifting heavy objects off the ground, and last but not least, supporting our functions and activities through each and every day.
It seems dis-respectful to primarily use our Butts for such a heinous activity as sitting. So, the subject of this weekend's HomeWork.
No sitting for 24 hours. Period.
It is a 'holiday weekend' for most all of us, so this should be fairly easy to accomplish.
For one day (and night), over the weekend, you are not to sit on your Butt at all.
You are free to walk, squat, lean, and even lay flat. I specify lay flat because all cultures over the eons of existence have layed flat in order to sleep and so shall we. Only recently in human existence did people start sitting in chairs. Historically, mankind has squatted or rested upon a rock or on flat ground.
As an experiment for the HomeWork we are taking that one little step forward. We will not sit on any rocks, nor on flat ground.
If we are not sleeping while laying flat, we will stand or squat. Period.
And, for a list of studies that examine the ill-effects of sitting, check out the list below.
Have a great weekend,
