There's a quote in that blog that I quite liked:

We’ve engineered movement out of our lives. We sit in chairs, stare at screens, and outsource physical effort to machines. Then we try to cram all our movement into 45-minute bursts a few times a week.

This is like eating only once a week and calling it a balanced diet. Most people are malnourished, not from lack of food, but from a lack of diverse, nutrient-dense movement.
