2. An Uphill Hike

Walking will never burn as many calories as running does (more on this later), but taking an uphill hike sure can. As long as you have a backpack with supplies on your back and you walk at a normal, steady pace, you can burn more than 400 calories on a one hour hike. Hiking is way more fun than running, so plan to take a hike a couple of times per month to really switch things up.
