Mike Robertson has a great audio interview/podcast with Dan John. There are few people so brilliant that everyone should listen, but Dan is one.
He's given a lot of great interviews over the years, but I really like this one. All the training advice you can use, wrapped up in one interview. Go listen.
Dan's a really good guy, who's given me plenty of motivation and advice over the last couple of years. We were introduced in L.A., where this video was filmed. If you watch carefully, you'll see me squatting poorly all over the place. I've come a long way, and Dan kicked off the road to my "better" squatting. Enjoy!
