All my conditioning is for the purpose of martial arts. I go to the weight room as a martial artist, stretch as a martial artist, and do push-ups as a martial artist.
I'm strict with myself about giving in to the temptation of cosmetic training. If you train for function, your looks will take care of themselves. Take a look at any athlete in a sport demanding high levels of relative power - they only train for function, but they look great.
The world's a will to power and nothing besides
