I’m not sure what you mean by pseudo science here.

It’s a structured way to change your running style. The guy also has some opinions.

I did not do the actual Pose seminars (we did try though). Our coach did and was passing things on. We often looked at top runners to see what they were doing and tried to learn what we could.

If you want proof that this is the best way for everyone. Well, this is the fitness industry. You’re not going to get that! Listen to what they have to say if you think it could be useful for you. Give things a good try. If they work, keep them. If they don’t, discard them.

All I can say is that this method seems reasonable and now I can run on my bum knee with no problems.
