I jogged a little more than yesterday and good thing my right foot wasn't acting up, though it was in the very beginning. However, it was hard to believe that I had a hard time to keep up with K's pace. Sometimes I think my endurance hasn't improved much yet, especially K didn't do exercise as regularly as I do, and yet he still has better pace than me.. It put me down in some ways, makes me feel all my efforts on P90X are useless. Yea I'm pretty competitive sometimes.
