The different style guides are designed for their particular environments. Most American newspapers and magazines follow AP, but most book publishers follow Chicago. Academics in the humanities tend to follow MLA, while academics in the social sciences tend to use APA. Hell, IEEE has a style guide for electrical engineers.
So do whatever you prefer. I tend to use Chicago because that’s what I know best, but I have worked professionally in writing and editing publications that followed the Chicago rules.
It’s been a few weeks since this comment. You still doing Tactical Barbell? I’m looking to switch to incorporate some conditioning work more formally after Labor Day (which will be my testing day to lock in my powerlifting totals before turning to other fitness goals).
What do you like or dislike about this program?
