Plan developed by Mindy Solkin, owner and head coach of The Running Center in New York City.

You're stepping things up a bit and adding a third day of walking/running to the program. "Now that you've started to build a base, you need to add a few more miles to your weekly program," explains Solkin. Keep the walk/run intervals at about a 2 to 1 ratio (4 minutes of walking, 2 minutes of running), and aim to maintain an even pace through each interval.

Your Workout

Walk: 4 minutes (50% intensity, or about a 17:00/mile pace)

Run: 2 minutes (60% intensity, or about a 12:30/mile pace)

Repeat 5 times.
