I find jumping rope and fartlek training to be extremely effective for cardio. Doesn't take much time, doesn't require much space. Also bodyweight exercises (pushups, pullups, muscleups, dips, pistols) are just as good as weight training (unless you're very advanced and need to lift more than you weigh to advance) and require less equipment.

Yes, great info... also HIT training(High Intensity Training) for 20 minutes burns more calories than a hour of regular cardio but make sure your heart can handle it.

Watch out for Special high Intensity Training, however... ;-P
