Sprint!

Wiser Health is all about efficiency. So we advocate sprinting like a track star. Run fast to run faster. Sprinting forces your body to go all-out, working the lungs, heart, legs and more. You can force your body to do a lot of work in a short amount of time.

You can sprint anywhere there's some open space, on a treadmill, on a court, in the park, on a bike. Mix in sudden sprints as part of your regular run. Race your friend to the next stop sign.

Watch Usain Bolt for inspiration.
