Pilates Calories Burned

Pilates Calorie Burn by Type, Weight & Duration

These figures use the MET (Metabolic Equivalent of Task) formula—the same method used by the Compendium of Physical Activities, the peer-reviewed standard for exercise calorie estimates. Mat pilates has an assigned MET of 3.0; reformer pilates is 4.5. Expect individual variation of roughly ±15% based on your effort, fitness level, and how the class is structured.

Which Type of Pilates Burns the Most Calories?

The gap between mat and reformer is real—and it comes down to resistance. The reformer adds spring tension, which forces more muscle activation per movement. More muscle working = more energy used = more calories burned. Here’s how the main formats compare.

Mat Pilates — Steady, Accessible, Moderate Burn

Mat work uses your bodyweight as the primary resistance. A typical 60-minute class burns around 170–272 calories depending on weight and pace. It’s the most accessible entry point—no equipment cost, doable at home, and easy to scale for beginners.

Research by Michele Olson, Ph.D., FACSM—who measured oxygen expenditure directly in 12 subjects across mat pilates intensity levels (as cited by LIT Method)—found that a beginner session burns about 4 calories per minute (240/hour), while advanced mat pilates reaches 7.5 calories per minute (450/hour). The difference is how much effort you’re actually putting in, not just what level is labeled on the class.

Reformer Pilates — Higher Resistance, Bigger Numbers

The reformer machine adds spring-based resistance to almost every movement, recruiting more muscle simultaneously. That drives the MET value up to 4.5, roughly 50% higher than mat work. A 150-lb person doing a standard reformer class for 45 minutes burns around 230 calories—versus 153 for the same duration on a mat.

Studio reformer classes typically run 45–55 minutes. The variation in class format matters a lot here: a slow, rehabilitation-style session will land closer to 200 calories per hour, while a high-intensity class with quick transitions and heavier spring loads can push 350–450 calories for a 150-lb person. According to body-weight-segmented data from Lagree Fit 415 (which cites VeryWellFit and Harvard Health methodology), a 150-lb person in a standard reformer class burns approximately 170–190 calories in 45 minutes—consistent with the MET-based calculations above.

Wall Pilates — Similar to Mat, Growing Fast

Wall pilates uses a flat surface for support and added leverage during bodyweight movements. Because it’s still fundamentally bodyweight resistance, calorie burn is comparable to mat pilates—roughly 170–260 calories per hour depending on your weight and pace. It’s not a higher-burn format, but it’s an effective option when you don’t have equipment or floor space.

High-Intensity Hybrid Formats

Some studio formats blend pilates principles with cardio intervals and reduced rest time. These classes aren’t traditional pilates—they borrow the equipment and movement vocabulary but push heart rates significantly higher. Calorie burn can reach 350–500+ calories per 45-minute session for an average-weight person, closer to what you’d see from a HIIT class than a classic reformer session.

The Math Behind Pilates Calorie Estimates

Every calorie estimate in this article (and most you’ll find elsewhere) comes from the same place: the MET formula. MET stands for Metabolic Equivalent of Task—it’s a ratio comparing the energy cost of an activity to sitting at rest.

The formula: Calories burned = MET × weight in kg × time in hours

Worked example: A 150-lb person (68 kg) doing reformer pilates (MET 4.5) for 45 minutes (0.75 hours):

4.5 × 68 × 0.75 = 230 calories

MET values for pilates come from the Compendium of Physical Activities, a peer-reviewed database maintained by exercise science researchers at Arizona State University. The 2024 update is the most current version. Mat pilates sits at approximately 3.0 MET; reformer is assigned 4.5.

One important caveat the Compendium itself notes: these figures are population averages. They don’t account for individual differences in body composition, age, movement efficiency, or fitness level. Your actual burn could run 10–20% above or below the estimate.

What Actually Affects How Many Calories You Burn

Body Weight — The Biggest Variable

More mass requires more energy to move. Looking at the tables above, a 200-lb person doing the same mat class as a 125-lb person burns about 60% more calories—272 vs. 170 per hour. This isn’t unique to pilates; it applies to every activity calculated using the MET formula.

Intensity and Resistance

On the reformer, more spring tension means more muscle recruitment, which directly raises your calorie expenditure. In mat work, the equivalent is moving through exercises with controlled effort rather than momentum. A class where you’re actively fatiguing the target muscles burns more than one where you’re going through the motions.

Your Current Fitness Level

Newcomers sometimes burn slightly more per session as their bodies adapt to unfamiliar movement patterns. As you get more conditioned, your body becomes more efficient—which means you need to add resistance, duration, or intensity to keep energy expenditure high.

Session Duration

Most pilates classes run 45–55 minutes. Shorter sessions obviously yield fewer total calories, but they’re not wasted—even 30 minutes of focused reformer work delivers 128–204 calories depending on body weight, plus the muscle-building benefit that accumulates over time.

Pilates vs. Other Workouts: Calorie Comparison

Context matters when evaluating pilates for weight management. Here’s how it stacks up against common alternatives for a 175-lb person in a 60-minute session, using MET-based calculations from Fitness Volt’s verified comparison table:

Reformer pilates compares reasonably to walking and beats yoga on calorie burn while remaining genuinely low impact. For anyone managing joint pain, post-injury recovery, or simply preferring low-impact training, the reformer’s calorie output is solid. Where pilates can’t compete is with sustained cardio like running or cycling—those activities are simply more efficient at burning energy per hour.

Is Pilates Actually Good for Weight Loss?

The honest answer: yes, with conditions. Pilates alone—a few sessions per week, no dietary changes—will produce modest results. Paired with a reasonable calorie deficit from diet, it becomes a meaningful contributor to weekly energy expenditure.

The Math on Losing 1 Pound

One pound of body fat requires burning roughly 3,500 calories more than you consume. Running the numbers on pilates:

• Mat pilates at 150 lbs: ~204 calories/hour → roughly 17 one-hour sessions to burn 1 lb from exercise alone
• Reformer pilates at 150 lbs: ~306 calories/hour → roughly 11 one-hour sessions

That’s without any dietary adjustment. Add a modest 200-calorie daily deficit from food, do three 45-minute reformer sessions per week (burning ~690 calories total), and you’re looking at a combined weekly deficit of roughly 2,100 calories—about 0.6 lbs per week, or ~2.4 lbs per month. That’s a realistic, sustainable pace.

The Muscle-Building Bonus

Regular pilates builds lean muscle, which raises your basal metabolic rate—the calories your body burns at rest. This effect is modest for pilates compared to heavy strength training, but it’s real, and it compounds over months of consistent practice. More muscle means your body burns more energy throughout the day, not just during sessions.

How Often Should You Do Pilates for Weight Loss?

The research by Michele Olson found that meaningful weight loss results require at least 4 sessions per week at 45–60 minutes each—and that holds specifically for intermediate and advanced intensity levels, not beginner-paced classes. For most people, 3 sessions per week combined with dietary awareness is a realistic and sustainable starting point.

5 Ways to Burn More Calories During Pilates

1. Increase reformer spring resistance. Heavier springs recruit more muscle, which directly lifts your energy expenditure. Progress resistance gradually rather than jumping to maximum tension.
2. Cut rest time between exercises. Keeping the heart rate elevated through shorter transitions raises the overall caloric cost of the session—even without changing the exercises themselves.
3. Choose higher-intensity class formats. Not all reformer classes are equal. Look for formats described as “cardio pilates,” “athletic pilates,” or classes that incorporate jumping on the reformer.
4. Go four sessions per week instead of two. The cumulative weekly calorie total matters more than any single session. Adding one or two sessions per week roughly doubles your weekly pilates-related energy expenditure.
5. Actually engage the muscles. Half-reps and passive movements waste the session. Full range of motion with deliberate muscle engagement burns significantly more than going through the motions. Quality matters more than speed in pilates.
