Sticking with a diet of 1500 to 2200 calories per day can be tough, particularly for those of us who need a lot of food to stay active. Thankfully, there's always exercise to help us burn off any extra calories we ate during the day.

Want to burn 600 calories in an hour? You'll find it's not as hard as you might think:

1. High Impact Aerobics

General aerobics are great and can burn 605 calories in one hour for those over 200 pounds. For those around 180 pounds, you'll need to do an hour of high-impact aerobics to get that 600-calorie burn.

2. Basketball

A competitive game of basketball can burn about 650 to 750 calories in an hour, provided you really hustle as you play the game. Don't stop running, and make those full court breaks as often as you can to hit the 600-calorie mark before the hour is up.

3. Boxing

Want to blast 600 calories in under an hour? A boxing match in a ring will burn at least 700 calories, while general sparring with be closer to 600. No matter how small or light you are, hitting the boxing gym hard is a great way to torch 600 calories.

4. Calisthenics

You may not have heard this word since the early '90s, but it's a term that refers to general body-weight exercise. We're talking situps, push-ups, pull-ups, etc. Hit them hard and do them fast, and you can burn 600 calories in a single hour.

5. Rowing

Strap into that rowing machine and get your body moving. You can easily burn 600 calories per hour with vigorous rowing, but even moderate rowing will be enough for a 190-pound man or woman to reach 600.

6. Circuit Training

Instead of giving yourself a breather between every set at the gym, try circuit training and never stop moving. Follow a push movement with a pull movement, and follow that with a leg exercise. In just an hour, you'll be 650 calories lighter.

7. Cross Country Skiing

You'll need to ski at a fairly moderate pace to burn 600 calories in an hour, but the faster you go the more you'll burn. If you're racing cross-country, you can burn the 600 in half an hour.

8. Cycling

Get on that bike and pedal like a demon to burn 600 calories in an hour. As long as you're pushing harder than 14 MPH, you'll burn those 600 calories in under an hour.

9. Farming

Whether you're baling hay or cleaning your barn, an hour of solid work will burn 600 calories.

10. Football

You can play tackle, touch or flag football, but make sure you're the wide receiver or running back if your goal is to burn 600 calories.

11. Ultimate Frisbee

We're not talking the fun, relaxing game of Frisbee you play with your kids in the park. This is Ultimate Frisbee, a highly active, fast-paced game that gets as competitive as any football match. A great way to burn 600 calories in an hour!

12. Forestry

Unleash your inner lumberjack, and get to work clearing trees. Chopping down trees (with a chainsaw, not an axe) for an hour is a great way to burn well over 600 calories, and the burn increases if you do the hard work of hauling the logs yourself.
