We recently introduced our latest LES MILLS GRIT class, the classes are 30-minute high-intensity interval training (HIIT) workouts, designed to improve strength and build lean muscle. It is scientifically proven that LES MILLS GRIT™ Works. The class involves short, intense rounds of high intensity exercises followed by small periods of recovery. The class encourages you to go as hard as you can for a short period of time, rest and then repeat. Research has proven that it’s intensity not volume that get’s results so that could be good news for those who dread clocking up hours on the treadmill.
The HIIT high intensity training means you burn calories for hours after your workout, it also enables you to burn 9% more fat which means it is 17% more effective that your standard aerobic training. All it takes is 30 minutes twice a week to increase your aerobic fitness.

As Les Mills Head of Research Bryce Hastings explains, LES MILLS GRIT is designed to push the heart rate up as high as possible, as often as possible in a 30 minute phase. “So we design the workout to have these very high spikes of intensity, followed by a complete recovery. And it’s those spikes that generate the types of biochemical changes that are very specific to a HIIT workout.”
All it takes is two 30 minute LES MILLS GRIT classes to create significant changes to your fitness, lower the risk of cardiovascular disease and improve your body composition. Book one of our classes today for a better workout that fuels change.
