I hate cardio -- I'm so much better at toning and flexibilty work.
I do tolerate Leslie, in small doses. (Like, 1 mile at a time.)
I also don't mind kettlebell swings. They raise the heart rate without a lot of bouncing/jiggling, and they're still effective in short bursts. (Swing a bit, rest a bit, swing a bit, etc.)
I sometimes enjoy kicking and punching-type workouts. Cathe's KP&C was a favorite of mine for a while, as well as Weight Watchers Punch workout. As long as the choreography isn't too complex (but haven't done much lately).
Hula hooping.
(I also enjoy swimming and hiking but don't get to do them very often.)
