I noticed, while traveling in Asia, that their toilets required squatting. Also that many people squatted while waiting for the bus, or just anytime. And that during my month long internship that there were no cases of sacroiliac dysfunction, something that is common in NA. I decided to keep squatting on a regular basis. Now, much more recently, I've seen a "paper" regarding squats and blood glucose levels - the experimental group did 10 squats every 45 minutes during their work day/week, and had significantly lower BGL/ HbAIC by the end of the study. This was brought to my attention by Rhonda Patrick, Phd., if you wanted to go find the citation. No guru ever told me, "If one's body is capable of a given range of motion, then one should do that range of motion regularly, so one doesn't lose that ROM." In fact, it's entirely possible that I've never had a conversation with a guru. shrug
Squats, Lunges, Deadlifts, Pullups, Pushups, Dips - neither too much, nor too little.
