You’ve probably heard the buzz about HIIT workouts by now, and today we’re here to tell you that it’s true. These high-intensity routines are an incredibly effective way to rev your metabolism and sculpt every inch of your gorgeous body. HIIT (aka high-intensity interval training) mixes short bursts of all-out, high-intensity effort with periods of recovery. We like to do a few slower paced, total-body toning moves during this recovery time to really boost that metabolism.

HIIT workouts are fast and efficient, so they’re perfect for when you’re on the go. When you join the Studio Tone It Up app, you can sign up for tons of incredible workout classes, including HIIT, kickboxing, and yoga sculpt that you can do anywhere.

Today’s workout includes fives moves designed to tone your entire body. That’s the beauty of HIIT. It works your butt, abs, and upper body, all while raising your heart rate to give you that post-workout glow. Use these moves all season long whenever you need a quick sculpting routine.

Remember, HIIT workouts are designed to push your body, so make sure you’re refueling your muscles with plenty of protein. Give our favorite spring smoothies a try. They’re made with our clean, non-GMO Tone It Up Protein ($23), so you can replenish your muscles with essential proteins and rev your metabolism all day long.

Go through three rounds of the moves below. Rest for 30 seconds between each round.
