Hit the hills
Adding hills to any workout can boost calorie-burn from 16 percent on a slight incline to 70 percent on a steep hill.
Watch your form
Stand tall, take quick steps, bend elbows to right angles, and push off your toes to burn up to 30 percent more calories per minute than with sloppy form.
