How Many Calories Does Lagree Burn?
The Honest Numbers (2026)
Updated October 16, 2026 · 9 min read
Lagree has a reputation as one of the hardest 45 to 50 minutes in boutique fitness: slow, continuous reps on the Megaformer until your legs shake. So how many calories does it actually burn?
Studios often quote big numbers, and the research on Lagree itself is thin. Below we separate the claims from the evidence, show what the standard calorie formula gives at different intensities and body weights, and explain how to measure your own burn.

The short answer
Roughly 300 to 500 calories for most people, sometimes more
There is no independent study that has measured the calorie burn of a Lagree class. The figures you see come from studios and from estimates. Lagree studio marketing often quotes up to around 700 calories for a 50-minute class, while other estimates put a typical class at 300 to 600 calories.
The standard calorie formula, applied to a vigorous workout (6 METs), gives about 310 to 430 calories for a 50-minute class for people weighing 130 to 180 lb. Higher figures are possible if you work at a harder, sustained intensity, are heavier, or take a longer class. Lower figures are likely in a beginner class with more rest and set-up time.
The honest answer for you: wear a heart rate monitor for a few classes and look at your own numbers.
By the numbers
Estimated calories in a 50-minute class
Calculated with the standard formula: calories per minute = METs × 3.5 × body weight in kg ÷ 200. A MET is a multiple of your resting energy use; 6 METs or more counts as vigorous.
| Intensity (METs) | 130 lb (59 kg) | 150 lb (68 kg) | 180 lb (82 kg) |
|---|---|---|---|
| 2.8 METs (general Pilates, 2024 Compendium) | 145 kcal | 167 kcal | 201 kcal |
| 6 METs (vigorous threshold) | 310 kcal | 357 kcal | 431 kcal |
| 8 METs (hard, sustained effort) | 413 kcal | 476 kcal | 574 kcal |
These are estimates, not measurements. Lagree has no Compendium entry of its own; the 6 and 8 MET rows show what the formula gives if a class reaches those intensities.
Why the numbers vary
What changes your Lagree calorie burn
Body weight
Calorie burn scales with body weight. At the same intensity, a 180 lb person burns about 40% more than a 130 lb person.
Time under tension
Lagree keeps you moving slowly with little rest. The less time spent changing springs or resting, the higher the average intensity.
Spring load
Heavier springs on slow reps raise effort. Lighter loads to protect form are smart for beginners but lower the burn.
Class length and level
A 45-minute beginner class burns less than a 50-minute advanced one. Count only the minutes you are working.
Compared
Lagree vs Pilates calories
| Lagree | Reformer Pilates | |
|---|---|---|
| Intensity | Designed to be high-intensity and low-impact | Usually light to moderate; the 2024 Compendium lists general Pilates at 2.8 METs |
| Research | No published calorie study we could find | A 2025 review of four studies found 65 to 214 kcal per session |
| Typical estimate (150 lb, 50 min) | About 357 kcal at 6 METs | About 167 kcal at 2.8 METs |

Measure it
Chest strap heart rate monitors
A chest strap reads heart rate more directly than a watch. It sends it to your phone or watch, which turns it into a calorie estimate.
1Most Accurate
Polar H10 Heart Rate Monitor Chest Strap
In stock · Sold by Amazon.com
Polar calls the H10 the most accurate heart rate sensor in its history. A chest strap reads heart rate from the electrical signal of the heart rather than light through the skin, which suits a workout full of gripping, planks and wrist flexion.

- ·Bluetooth and ANT+, usable at the same time
- ·Pro chest strap with silicone dots to stay in place
- ·Works with most HRM-compatible apps and watches

Do it yourself
How to find your own Lagree calorie burn
- 1
Enter your details
Set your age, weight and height in your app. Calorie estimates depend on them.
- 2
Choose a strength or HIIT activity
Pick an activity type that matches the effort. A watch set to a low-intensity activity may estimate differently from one set to a strength or interval workout.
- 3
Wear a chest strap
Pair a chest strap with your watch or phone so heart rate comes from your chest, not your wrist.
- 4
Average three classes
Record three to five classes and use the average. One class tells you little; a trend tells you a lot.
Keep it in perspective
Calories are only part of the story
Lagree is a strength and endurance workout. Its value is in muscle, stamina and consistency, not only the calorie number on your watch.
If weight loss is your goal, read our guide to Lagree for weight loss, and speak to your doctor or a registered dietitian for personal advice.
Frequently asked questions
How many calories does a 50-minute Lagree class burn?
There is no independent study of Lagree's calorie burn. Using the standard formula for a vigorous (6 MET) workout, a 50-minute class burns about 310 to 430 calories for people weighing 130 to 180 lb. Studio marketing often quotes up to around 700.
Does Lagree burn more calories than Pilates?
Usually, yes. Lagree is designed to be high-intensity, while the 2024 Compendium of Physical Activities lists general Pilates at 2.8 METs, a light intensity. A 2025 review of Pilates studies found 65 to 214 calories per session.
Is 700 calories in a Lagree class realistic?
For most people, it is at the high end. The formula only reaches about 700 calories in 50 minutes for a heavier person working at a hard, sustained effort. Measure your own with a heart rate monitor rather than relying on a studio figure.
Why does my watch show fewer calories than the studio says?
Studio figures are general claims, while your watch uses your own heart rate and details. Wrist readings can also slip during gripping and planks; a chest strap gives a steadier heart rate signal.
What is the best way to track calories in Lagree?
A chest strap heart rate monitor, such as the Polar H10, paired with a watch or app, averaged over several classes.
