First Day Back

Today was my first day working out again after about a one week break. My body liked the rest but getting back in the groove was tough. I picked up where I would be in my program if I took no break. Today's workout was 4 x 400M with rest equal to the previous 400M time. I think my course in the neighborhood is closer to 500M but that's the best I can do with my time constraints right now.
