Rumors of my death have been greatly exaggerated.
Things started to go awry at around the end of October. The gym was closed on Halloween (which is a stupid reason), so I went back on Saturday to squat. My left knee was giving me problems, and I didn't get past 355. For some reason, the last thing I wanted to do was acknowledge weakness even more by recording it.
Fast-forward through some more mediocre sessions, and I'm back where I need to be.
