Even though I've never met or trained with DB, I'm a fan. As a result, I was watching @jlw and DB discuss the "Spread of the Modern Technique". In that video, DB was discussing Weaver/Modern vs. Isosceles, and I thought I was following along (thought that I knew the difference), then DB said some stuff that totally threw me, and now I don't get it. Specifically, (if I understood/heard it correctly) the Weaver/Modern "isometric/muscle" pressure vs. the Iso "skeletal pressure".
Help.
