Yah, and that's in line with Jason's evolving view that it's not so much about BF as it is about BF form. BFR is the royal road to getting there, but competitive shod runners like Magness have been teaching proper form for years. On another page he pooh-poohs high volume running, and argues that no modern, competitive runner would only do that and avoid higher intensity work. It's all about finding a proper mix. And I have to say, after just 5-6 weeks of working hills into my weekly routine, I'm already starting to notice some benefit (along with sore glutes). On today's run I'm going to do some faster blocks towards the end.
