I did it before the run, and again after the run. Doing it before was REALLY helpful. Far less of a stretching pain. My knees still kind of hurt as did my calves, but far better. Then I did them again after I ran. Made it more bearable.
I've decided to leave 3FC, In the crowd of so many, those of us with no success that have the audacity to feel bad about our incredibly slow and almost stagnate weight loss, are merely a nuisance to those that are successful. I hope everyone else finds the support they need.
