High-intensity interval training is known to burn serious amounts of fat, seriously fast. But not just any fat. New research shows that specific forms of high-intensity interval training can be key to cutting fat from your tummy.
The tummy trimming benefits of high-intensity interval training are highlighted in a recently published study into how different approaches to training can affect fitness and body composition in healthy adults1. The study tested two groups of exercisers. One group followed a conventional gym training program four days a week, the other did two conventional gym workouts and two high-intensity interval training based LES MILLS GRIT™ Cardio workouts a week. Both groups trained for the same total amount of time each week.
At the end of the eight-week study both groups saw a reduction in total body fat, but it was those doing high-intensity interval training who really took the fat burning up a notch. These individuals eliminated an average of 2.2cm from their waistlines and experienced an overall loss of 2.2% visceral fat – that’s the awful gut fat that clogs up our organs, affects our hormones and increases the risk of health problems such as type 2 diabetes. They also benefited from a significant increase in cardio-respiratory fitness, sprint speed and arm strength.
While the results are significant, the length of the work outs was not. Those who incorporated the high-intensity interval training didn’t need to slog it out for hours at the gym – the LES MILLS GRIT sessions they did twice a week were just 30-minutes long.
LES MILLS GRIT workouts are short, but explosive. Combining intervals of speed training with body weight exercises such as squat jumps and lunges, they are designed to maximize calorie burn during the workout, and beyond.
All it takes is the introduction of just two LES MILLS GRIT workouts a week and you can increase aerobic fitness, grow lean muscle tissue and amplify fat burn – all while you whittle away the waistline. Find a class near you or get 24/7 unlimited access to online workouts with LES MILLS On Demand.
