Considered one of the quickest ways to take your fitness to the next level, the high-intensity interval training of a LES MILLS GRIT workout builds cardiovascular fitness and lean muscle while sending calorie burn through the roof. Read on for all you need to know about LES MILLS GRIT, brought to you by LES MILLS Fit Planet.

What is high-intensity interval training?

High-intensity interval training (HIIT) is any workout that involves short, intense bursts of effort followed by periods of recovery. The idea is that you go as hard as you possibly can for a short time, rest and then do it again. The intense intervals, particularly the use of the recoveries, allow you to keep reaching your maximum training zone, which is where the results kick in. The HIIT formula can be applied to almost any type of exercise – sprints, cycling, group exercise and functional training.

Why is Les Mills Grit the ideal HIIT workout?

Every LES MILLS GRIT workout features a variety of functional exercises that are scientifically structured and tested to ensure they drive the heart rate into specific training zones at certain times. These highly-effective exercises are matched with powerful music, and led by highly skilled coaches who motivate you to push yourself to your max.

Why should you do LES MILLS GRIT?

If you’ve reached a fitness plateau, LES MILLS GRIT provides the challenge and intensity you need to take your fitness up a notch. With just a few short sessions a week you can rapidly improve aerobic fitness and increase athleticism. You’ll unleash fast-twitch muscle fibers and grow lean muscle tissue, which is key to burning fat.

How many calories do you burn doing LES MILLS GRIT?

In a 30-minute LES MILLS GRIT workout you can expect to burn an average of 320 calories* – and that’s just the beginning. LES MILLS GRIT puts your metabolism into overdrive and generates accelerated changes in body composition.

What exercises do you do during LES MILLS GRIT?

High knee runs, burpees, mountain climbers, tuck jumps and squat jumps … these are just some of the moves you can expect in a LES MILLS GRIT workout. The LES MILLS GRIT Athletic option also features functional speed and agility training moves, and if you opt for the LES MILLS GRIT Strength option you’ll do sets of weighted squats, lunges, deadrows, and clean and presses too.

How often should you do LES MILLS GRIT?

While it’s easy to get hooked on the endorphin high of HIIT, you shouldn’t do LES MILLS GRIT more than twice a week. New research reveals optimal results come when you limit the time you spend with your heart rate above 90 percent maximum to 30-40 minutes per week (which equates to two LES MILLS GRIT workouts).

How fit and strong do you need to be?

If you’re new to fitness, diving head first into HIIT is not a wise move. We suggest you build a good level of base fitness and have a regular routine of cardio and resistance training before you tackle HIIT.

While it’s ideal to have some base fitness, you don’t need to be super fit or strong. LES MILLS GRIT workouts feature simple movements that are relatively easy to master, and while the coaches are there to push you to your max, you can go at your own pace. In fact, if you need to stop to catch your breath it’s a good thing – as that indicates you’ve been pushing your body to the max training zone.
