20 min workout

I only managed to do a 20 min workout consisting of stretches, pushups, situps, plank and bicycle kick today because I was tired. Got back from work late at night and even though I wanted to just grab dinner and sleep, I forced my self to do the workout. I managed to do it because of some good advice I read somewhere which said that you must get angry at your laziness (your body) in order to push yourself to workout. It works.
