I took a long power walk this morning, around 5 miles. Did a pretty good pace; I know I finished 4 miles in under 60 min. I don't get the runner's high from power walking, but I am still nursing a sore quad from my last run. Took the day off from the park weight/ab machines. I may dig out my dumbells and do some arm exercises later. We'll see. I'm pretty depressed lately (or maybe mixed bipolar?) so my motivation is up in the air at the moment.
