We've already shown you how to calculate activity-specific calorie burn with Wolfram Alpha, but if you're trying to pick exercises based on their calorie-burning powers, this chart will help you out.
If you've ever wondered whether you burn more calories hiking or canoeing (surprisingly, the answer's canoeing), this chart can point you in the direction of the most beneficial form of exercise. It's not quite as specific as Wolfram Alpha, but it can give you a pretty good idea at a glance, and still takes the most important factors into account (like weight and rigorousness of exercise). Plus, this list has everything from cycling to basketball playing to hacky sack to cleaning gutters — whatever your plans are for the day, you can probably find out how many calories you'll burn with this list.
Hit the link to check it out, and be sure to keep your calorie burning efficient with interval exercises and NEAT activities.
