YOU DON’T NEED a treadmill to torch calories. In fact, if your goal is to burn fat, high intensity workouts and circuits are essential. Aside from being a quick method to getting in a great workout, intense periods of work with short recovery segments, allow you to keep the workout intensity high while still maintaining form; they’re also extremely effective for transforming your physique. Intense circuits also stimulate muscle-building hormones and put your body in a perfect state to build lean mass.

The key to making an interval workout is including movements that challenge your entire body in a single exercise. Aim to include at least two exercises back to back before allowing your body to recover. Catch your breath in between rounds, but don’t allow yourself to recover fully before attacking the next set. Include at least a day of rest in between workouts as these intervals are intense, and you’ll see results a treadmill could never replicate.
