Instead, the secret to running to get leaner is to incorporate some interval work, or HIIT.

But before you jump in running, be sure to perform a proper warmup, and stretch it out.

Once the incline and speed are set, hop on, and sprint hard for 30 seconds.

Rest for 30 seconds, and then repeat this workout for 10 rounds.

Run your way up to the top, then go back down.

Rest for 1 to 1 12 minutes (if needed) before performing another set.

Depending on the length of the hill and stairs, aim for 6 to 8 rounds.

(Four hundred meters is equivalent to one lap around the track.)

Go ahead and start running at a fast pace around the track.

Then, once you’ve finished, rest for 2 to 3 minutes.

Aim for 2 to 4 rounds total once a week.
