The topic is exercise and movement, but I'm not going to go full-on Jillian Michaels on them - because that exemplifies the core of what is wrong with our culture of health with regard to activity.
I want these wonderful people to think different about movement ... from the reason why they're active in the first place, to manage their expectations, and to take the pressure off so that it is more of a joy than a chore.
So. No grunting or yelling. No pain, all gain.
Time to change the culture of health.
