As a trainer to stars like Heidi Klum and other Victoria's Secret models, Andrea Orbeck knows how to whip a body into shape. If you're looking to step up your shape-up game, this 30-minute cardio interval plan she shared with us is a great way to boost the fat burn and tone the lower body.
The workout is simple — after a four-minute warm up, repeat the interval portion. End with a cool down and 10 minutes of stretching to soothe your muscles.
This can be done in the gym or outside!
