Yesterday after work, I did the next run on my training schedule, which was an 80-min easy run. I ran on the treadmill at 5.6 mph for 80 minutes, which came to a distance of 7.45 mi. This run felt pretty blah - I don't think I was in the mood. I have switched back to my previous running shoes to test the hypothesis that my current running shoes are contributing to my lower back pain. I'm really not sure that that's the case, but we'll see.
This morning, I did P90X2 X2 Shoulders + Arms. I burned about 115 calories. I increased my reps on a few moves.
