Yesterday I did a bit more than a half and hour of walking. You know, running is fine and fun, but I really like walking. I can think. I can plot the next chapter of my book! Walking rocks. I think I've developed an affection for it.
And today I tried this nifty work-out. No equipment, whole-body, very awesome. I went through it twice, and then added on 5 min. of plyometrics for good measure.
