Adding sprint bursts to your treadmill workout is a true game changer, even if you're new to running and mix walking into your workout. Playing with speed burns more calories, stokes your metabolism to burn more calories after your workout, and helps increase your speed as a runner. Plus, mixing your speeds helps fight belly fat — talk about a winning combination.
The speed bursts in this workout only last 30 seconds with a full minute to recover. But the moderate pace is intended to push you, too. The first sprint may be slower than the last since you are warming up!
As always, feel free to adjust the speed up or down as you feel necessary; just make sure you're challenging yourself. If this workout doesn't float your boat, then check out our other treadmill workouts .
