Feel Like a Badass (and Get Your Anger Out) With This Empowering Workout

"No matter what you are going through, after running up a hill at max speed multiple times, you will be a lot more chill afterwords," said Chris. And we couldn't agree more.

"Pick a hill, and a finish line that will take about 20-30 seconds to reach. Run the distance as fast as you can, walk back down and repeat. You should rest anywhere from 60-90 seconds. Aim for 6-10 sprints." If you don't have a hill near you, pick a flight of stairs, or set your treadmill to a steep incline and go, go, go!
