With HIIT, otherwise known as high-intensity interval training, you can bang out impactful, serious workouts out in almost no time. This, plus the fact that they work is a big part of their rising popularity in the past few years. Research shows that when you target heart rate through HIIT, not only do you burn more fat during the workout, you continue to burn fat for 24 hours after you finish. That means a 20-minute sweat session will raise your fitness game far more than a 6-minute run ever could.
HIIT workouts are often divided into categories like strength, core, and cardio. But say you have 20 minutes at the gym and want to cover all your bases. Possible? You bet! Follow this plan of 10 moves. Do each for 30 seconds, followed by 10 seconds rest. Because precise timing is an important part of maximizing HIIT workouts, consider getting a stopwatch or countdown clock to make sure you are sticking with the schedule.
