Ok, With unorthodox exercises, I think loading principles have to change. If we're not dealing with squat deadlift bench, I don't think you need to complicate things like the article does.
Are the 3 compounds not an option?
Well I think the article is complicated if for no other reason because Cal doesn't seem great at communicating, but that's not his job. Also I'm not sure if the loading principles have to change, I can still work off of percentages calculated by incorporation of bodyweight (exrx has some formulas).
The big 3 aren't really an option just because the weight I have available to me is limited(and there's no rack for the barbell, just a barbell), so I've had to choose exercises that are inherently so difficult or incorporate your bodyweight in a way that the load is lesser.
My main desire with using the methodology the article talks about is really getting a greater mastery of these three phases of dynamic movement. I know I can just apply 6 second eccentrics and paused lunges and clapping pushups or jumping lunges but I was trying to give some actual matching to the principles of the system rather than JUST the principles of motion.
