Few years ago it was fun to fight and then run, hide. Metal concerts in front of the stage? Again, total body work with punches-jumps, and all kind of stuff. Torn clothes and bruises all over the body the next morning.
I like "traditional" ways too. I don't have problem with boredom. Elliptical or treadmill, fuck it, I only need some good audiobook and headphones. I enjoy audiobooks, as they totally lift you out from the environment. You don't realise, and you've already finished with vacuum cleaning the house, cleaning up the kitchen, cutting the grass-hedge, and done 40-50 mins on some boooring cardio machine.
Don't try them on road cycling or during park walks though, good way to kill yourself on a pedestrian crossing :o)
Please note, that I count prowler-kettlebell-hillsprint (staircase is my way, as the countryside here has zero hills) as all out bursts of pure conditioning, and jogging-cycling-elliptical as light cardiovascular work (nonetheless, HR often gets up to 160, though the resting is lower than 60, so it's still poses some challenge).
