SFG WOD 101109 -- row

Rowing and shoulder mobility before I tweaked my back. It was cold outside, I hardly slept at all last night, and I did not warm up well. I shut it down about 20 minutes into the workout and went home. For whatever reason I am really struggling with the new programming. My diet and sleep are the same but my lifts and endurance are going down. Plus I'm feeling hurt more often. Maybe its the change in weather.
