6 HIIT Workouts To Melt Fat Under 45 Minutes


Unlike traditional cardio exercises like long-distance running or swimming (which take much longer to burn fat), High Intensity Interval Training (HIIT) workouts can be crushed in less than 45 minutes, and has even proven boost fat loss by increasing your insulin sensitivity by up to 58%!

So what exactly is a HIIT workout and why is it so popular? While it can take on many forms, HIIT workouts generally follow a similar principle; intervals of quick & short burst of movements that pushes your body to its metabolic limits and low-intensity intervals for quick recovery.

This method of exercise pushes you to reach your maximum effort and gets your heart rate up so you can burn more fat and calories in less time. It is the convenience of getting an efficient full-body workout under an hour that makes HIIT workouts an obvious choice for busy professionals who are strapped for time.
