Wanted to mention in this thread, in case people aren't aware, Wendler has recently released Beyond 5/3/1.

It has some interesting ideas about extending the volume in 5/3/1 by doing what he calls "joker sets". (Maybe we're not the optimal demographic for that, but anyway...)

On the downside, it has so many different variations on the program, some readers might end up with option anxiety trying to pick which version of the program to run. For me, it was cool to read through all the options to get a sense of how "programming" works in general.
