I'm almost done with Phase 1 of my first German Volume Training. I like the structure of it, even if it's a little boring, and I'm definitely seeing some results. But, as I'm 2 weeks into my first cycle (Test Prop and NPP) I don't know what to attribute it to.
After Phase 1 you get a few weeks break before Phase 2. During that I plan to do the "heavy and hard" as the other guy put it on all my favorite lifts.
