Get Outside and Torch Belly Fat: Running Interval Workout

You've overstayed your welcome, belly fat. If you've been running consistently but still, you look down and can pinch an inch (or several) from your middle, it's time to kick that gut to the curb. Crunches aren't the answer, so change things up by adding high-intensity intervals to your routine. We recommend doing this 45-minute running workout outside; not only will it help diminish your waistline, doing speed intervals will also help increase speed and endurance.

After completing a five-minute walking warmup, repeat the below workout 35 times, and end with a five-minute walking cooldown.

30 seconds	Walk briskly (about 4.6 mph)	2
20 seconds	Run moderately (about 6.7 mph)	3.3
10 seconds	Sprint as fast as you can (about 8.6 mph)	2.2

Calories burned per minute: 7.5
Calories burned for warmup and cooldown: 40
Total calories burned: 302.5
