Treadmill - 10% incline @ 5 mph

This activity burns approximately 789 calories per hour

For many people, walking at a 5-mph pace is not quite enough to build aerobic endurance. If you'd like to challenge yourself, increase the grade of the treadmill 2% every 5 minutes until you reach 10%. You'll find that this elevation will be enough to raise your heart rate without putting yourself at risk for injury.
