Basketball...with or without talent, it is amazing how different cardio feels when you are not forced to work your sorry ass off on the stair master for 45 minutes a day behing some waddling fat-as-play-doh fuck-for-brains on the treadmill in front of you.
We are only human, and as such we don't like being bored. Basketball (the full-court variety), outdoor biking, and...well, SEX are all good cardio and do not corrale you into the gym for an additional 45 minutes a day.
Sorry, you still have to do ab work though.
