20-Minute Treadmill Interval Workout
You'll Feel Like a Total Badass After This 20-Minute Treadmill Workout
Ready to get your HIIT on with a treadmill workout? Barry's Bootcamp trainer Erica Stenz created this 20-minute, superintense sweat sesh just for you. (And we just did it — it totally kicked our butts! We left dripping in sweat.) The first part of the interval training plays with speed, and toward the end you'll add a little incline.
