The Yoga Boot-Camp Workout That Features Heart-Pumping Cardio and HIIT

You don't need to choose between cardio and yoga ever again. Heidi Kristoffer's CrossFlowX is a one-of-a-kind way to break a sweat that basically combines HIIT with a nice long stretch-sounds pretty great, right?

This flow follows a pattern of one minute of hard work followed by 30 seconds of rest for a balanced workout. But don't get it twisted. These poses and HIIT-like moves are not for the faint of heart. You'll recognize some of them from boot camp and others from your power yoga class. Put them all together and you have an efficient burst of movement that will give you a taste of what CrossFlowX is all about. Your body will be strong, lean, flexible, and-oh yeah-sweaty. Now get to work! (Next up: Yoga Poses for Stronger Quads and Toned Thighs)

How it works: You'll do some of the more HIIT-style moves at peak intensity for 1 minute, and rest during the yoga poses for 30 seconds to recover before jumping back into the cardio-based moves. Repeat the whole flow 3-5 times depending on how much time you have or how hard you want to work.
