Anybody Into physical culture?

Interesting. I am doing this version which, tbh, is basically just Starting Strength but with weekly rather than per-session weight increases.

The author does note that this version is adapted for people who don't know the Olympic lifts (which I don't).

How different is the program I posted above from what's in the book?

Be careful with the starr's 5x5 programming. The stuff you find on the net is bastardised and been through the hands of several generations of bros adding extra shit for their guns.

Starr was all about the powerclean as the core exercise. I have his book, let me know if you need to know anything.
