What happens when you mix yoga-inspired moves with the intensity of interval training? You get a super-short and powerful workout like this 11-minute core class.

In this video, instructor Ashley Galvin will lead you through a powerful series of moves that focus on strengthening your entire core, including your abs, obliques, and back body muscles. You'll work each muscle group to exhaustion then take quick rests to stretch and recover before getting back at it. This class is effective on its own, but it can also be used as a finisher after your favorite cardio session. You just need a yoga mat to get started.
