My main question to the "Neanderthal No More, Part IV" workout routine is whether we're allowed to add chess, arms, and legs to it? My main goal is to improve my posture so I'm curious because I don't want to be counter productive.
Also I don't understand what is meant by "global muscles" and "local muscles" at the beginning of the article. If they can be cleared up a bit for me that would be quite helpful. I'm planning on just following the routine so I don't know what "local muscles" will have to be worked on daily. Let me know. Thanks.
