I haven't had a decent workout in about a week due to lack of sleep and food. Tonight I worked out 3 times. The first time was awful, so I quit. Then I tried again, and it also sucked. Then, for some reason, I got huge burst of energy around 3am, so I decided to try again. Third time was the charm. My workout was awesome!
Now it's 5:30am, and I'm pumped...I will never get to bed.
