Get a sneak peek inside our March issue with this amazing interval plan from the Cardio Fast Lane column. We loved this routine so much we decided to take a page out of our own book (almost literally) and share it with you. Pin this routine to your board on Pinterest and follow SHAPE magazine on Pinterest for more workout inspiration. And don't forget to pick up a copy of the March issue for more fat-blasting workout plans like this, healthy recipes, and more.
