I thought about running today, but decided that the 5 crummy hours of sleep I got last night weren't helping my situation so I walked. Did a speed of 4.2 with an incline of 4. Haven't walked that since the very beginning of this challenge. I also decided it was time to start doing my "core strengthening/8 minute abs" video again as well as doing some with the free weights. I'm feeling burnt out with running/walking! Blarg.
