I occasionally write for other websites. Here’s a little piece I did on upper back curvature in the deadlift. Maybe you will find it useful. Note as always that I am available for coaching. I’d be glad to have such a discerning and thoughtful person (reader of karlschudt.com) as a client!
For barbell coaching, what is your contact information?

There’s a link in the sidebar.
Hopefully some day I can afford you. Today is not that day.
