“For example, in our stack sitting method (which is really healthy sitting, primal sitting, if you will), you have your behind out behind, but not exaggeratedly. That’s very important. Then your bones stack well and the muscles alongside your spine are able to relax. They’re not obliged to be tense. Now when you breathe, your whole spine lengthens and settles, lengthens and settles. There’s this movement which stimulates circulation and allows natural healing to be going on as you sit.
If you sit poorly, whether relaxed and slumped or upright and tense, you’ve lost all of that. So do we want to blame [all the adverse health effects] on sitting, or do we want to blame it on the poor sitting form? That’s my question.”
