what cardio workout works best for you? Just being curious on what you guys prefer! :P

I like to keep it short and intense, I do throw in some slow long distance (but I hate them with a vengance!)
Sprints, intervals and circuit training. My current fav is the race to 100 burpees, you can do it in less than 10 mins and it will slaughter you!

Recently I've been using the treadmill!!
