How many calories do you actually burn from Les Mills workouts?

We’re constantly asked how many calories you burn in various LES MILLS workouts. The fact is, while you can put a number on it, looking beyond calorie burn is often the best approach.  

There’s a wealth of different ways to work up a sweat. Some workouts burn maximum calories in a short space of time, others build strength and lean muscle, which helps you to sustainably burn calories for longer periods. Not all calories are burned equally, and different types of training will stimulate different hormonal and different physiological changes, even when the calorie burn is the same.

But still, calorie burn is something many exercisers like to keep track of.

With this in mind, kinesiologist and specialist in biomechanics and neurophysiology, Dr. Jinger Gottschall recently evaluated calorie burn totals from 477 different people across 12,000 LES MILLS™ workouts to find the typical calorie burn range for different LES MILLS programs. These numbers serve as a helpful guide, but it’s important to note that everyone is different. If you’re prepared to unleash your inner beast you never know how much you can burn – apparently Les Mills Program Director Glen Ostergaard has recorded up to 850 calories burned during BODYPUMP™!


During a BODYPUMP workout you'll raise your heart rate and increase calorie burn, but more importantly, you'll strengthen, shape and tone your entire body, and also improve bone density. While you can expect to burn an average of 400 calories during a 55-minute BODYPUMP workout, it’s the building of lean muscle mass that provides the long-term benefits. By building lean muscle mass you increase your body’s ability to effectively burn calories in the long term, as the extra muscle will raise your metabolism.

The average calorie burn is based on data collected from 12,000 workouts done by 477 participants. These 477 participants were aged between 18 and 62 years (the average age was 36 years) and were regular participants in LES MILLS workouts. The testing was conducted on releases between January 2018 and January 2020.
