Check out 5/3/1 variants like “Perioization Bible” or “Simplest Strength Template.” They are structured sorta westsidish. They can help you get your head around training the big lifts steadily, and filling out the program with targeted assistance work. Most of the good stuff from Westside is in 5/3/1.
After a few months of that, look into Joe DeFranco’s “Westside for Skinny Bastards.” It’s like a template with a planned structure, and you plug exercises in and out, just like Westside. But DeFranco lays it out in a very easy to use way. He programs the heavy lifting you want to do in a Fun, flexible way.
When that’s over, you’ll understand wave loading, rotating assistance work, the Max Effort Method, the Repitition Method and how to break records every workout while still leaving a little in the tank for next time.
Then find “The Max Effort Method” by Jim Wendler. Again, super straight forward and easy to understand and apply.
Only then, once you really have a handle on all that stuff, should you confuse yourself by trying to decipher Louie Simmons’ articles and books.
