I had a good workout tonight. I felt energized as ever, which I'm crediting to my high complex carbohydrate intake throughout the day (whole wheat pasta with my own sauce (fresh onion and mushroom)).
I also decided to start running again and ended todays workout with a 15 minute interval circuit:

05:00 - 9 mph sprint
05:30 - 7 mph run
06:30 - 8 mph sprint (tired as hell!)
07:00 - 7 mph run
08:00 - 8 mph sprint
08:30 - 7 mph run
09:30 - 9 mph sprint
10:00 - 7 mph run
11:00 - 9 mph sprint
11:30 - 7 mph run
12:00 - 6 mph cool down
13:00 - 5 mph cool down
14:00 - 4 mph cool down
15:00 - end
It's really amazing how long 15 minutes seems when you're enduring such physical stress, and as much as I wanted to stop, I kept telling myself to overcome the pain. I'm glad I did, because I felt good afterwards.
There's a sense of accomplishment I feel after completing a tough workout. Even if I've had a very unproductive day, finishing it with a tough workout would make the entire day seem worth it. A tough workout is also an excellent stress releaser -- no matter how hard my day was, finishing it with a good workout makes me feel as if I could start the whole day over, and go through it all over again.
