The Calorie Games

You burn:
295-409 calories/hour unicycling
354-490 calories/hour jazzercising
207-286 calories/hour practicing archery
708-981 calories/hour playing handball
590-817 calories/hour kickboxing
And more! For every 25lbs you are over 180, you'll burn about 116% more calories for each exercise (though it varies a little from activity to activity.)
