Forget clocking up more time on the treadmill. Research shows that it’s intensity not volume that gets results – whether you’re an active adult or an athlete, your fitness will fly when you add LES MILLS GRIT into the mix.
There’s no doubt that high-intensity interval training (HIIT) drives amazing results. Several studies, conducted with sedentary adults, provide compelling evidence that HIIT can rapidly build fitness. However, there’s been nothing to demonstrate how HIIT affects those of us who are already fit and active. Until now.
The Les Mills Lab teamed up with Dr. Jinger Gottschall of Penn State, to explore how a specific form of HIIT training, like LES MILLS GRIT can transform the fitness of regular exercisers.
The study compared a group of adults doing regular LES MILLS group fitness workouts for five hours a week with a group that substituted one of their hour-long cardio workouts (such as BODYATTACK®, BODYSTEP® or RPM®) with two LES MILLS GRIT workouts.
The research team measured aerobic fitness, body composition, upper and lower body strength, and cardiovascular risk factors, at the beginning and end of the six-week trial.
