Today was the beginning of the second cycle through 5/3/1. Now I can begin go see whether or not I'm making any real progress by comparing my week #1 of cycle #2 to week #1 of cycle #1. So far so good: Today I lifted 180lbs for 8 reps as compared to this time last month when I lifted 175 for 7 reps. I nearly had 9 reps, but, as can be seen in the video, I lost some precious time waiting for someone to walk by. My assistance work also improved dramatically. This time last month I managed 42 chin ups in 5 sets. Today I managed to do 50 in 5 sets. I also did 50 dips in 5 sets with 45lbs on the weighted belt (these felt pretty easy). Finished in the park with 8 hill sprints in 20 min. These felt good and fairly explosive.
