AMAZING Treadmill Interval Workout

This workout is guaranteed to kick your butt! In just one hour, you can get an amazing HIIT workout (which is fantastic for flattening the belly), get your cardio in and workout the quads, hamstrings, calves, and glutes.

I wouldn't suggest adjusting the time, but you can certainly adjust the speed(s) and incline(s) on each interval workout. Because it's interval training, you're so focused on the interval times that the hour goes by SUPER quick.

Would love to hear from people that give this a try and what you thought of it. I LOVE it, but only incorporate it one day a week into my weekly workout routines, as it kills your lower body for a few days.
