A one-hour mat Pilates session burns roughly 150 to 250 calories for most people at a beginner level, and 250 to 400 calories at an intermediate or advanced level. The exact number depends on your body weight, the type of Pilates you’re doing, and how hard the class pushes you. That puts Pilates in the moderate-intensity category, comparable to a brisk walk or a hatha yoga class, but well below running or cycling.
Calorie Burn by Body Weight
Your body weight is the single biggest factor in how many calories you burn during any workout, and Pilates is no exception. A 120-pound person doing reformer Pilates burns around 180 calories per hour, while a 150-pound person burns closer to 220 calories in the same session. At the higher end, someone weighing 185 pounds doing mat Pilates can expect to burn toward the top of the 170 to 250 calorie range for a beginner-level class.
These numbers come from metabolic estimates, not direct measurements on every individual. Your actual burn will shift depending on how much muscle you already carry, your fitness level, and even the temperature of the room. But as a general guide: take your body weight, and expect roughly 1.2 to 1.6 calories burned per pound per hour for a standard mat class.
Mat Pilates vs. Reformer Pilates
Reformer Pilates tends to burn slightly more calories than mat Pilates because the machine adds resistance through springs and an elevated, sliding platform. That extra resistance forces your muscles to work harder to control each movement, which nudges the calorie burn upward. For a 150-pound person, the difference might be 20 to 40 extra calories per hour on a reformer compared to the same exercises on a mat.
That said, the gap between mat and reformer narrows significantly when the mat class is more advanced. A challenging mat session with fast transitions, sustained holds, and full-body movements can match or exceed a moderate reformer class. The intensity of the programming matters more than the equipment itself.
Beginner vs. Advanced Sessions
The jump from beginner to advanced Pilates nearly doubles the calorie burn. Beginner mat Pilates sits in the 150 to 250 calorie range per hour, while advanced classes can push to 400 calories or more. Several things account for this difference.
Advanced Pilates classes move faster, with shorter rest periods between exercises. They incorporate more complex, multi-joint movements that recruit larger muscle groups simultaneously. Your heart rate reflects this: studies measuring heart rate during Pilates classes have found values ranging from 86 to 110 beats per minute, with participants typically working at around 62% of their maximum heart rate. In progressive programs, that intensity can climb to 75 to 80% of max heart rate by the later weeks, which is solidly in the moderate-to-vigorous zone.
If you’re new to Pilates and disappointed by the lower calorie numbers, keep in mind that your burn will naturally increase as you advance. Stronger muscles can handle harder exercises, which demand more energy.
How Pilates Compares to Other Workouts
Pilates occupies a middle ground between gentle flexibility work and high-intensity cardio. Here’s how a one-hour session stacks up:
- Hatha yoga: 150 to 250 calories per hour, roughly equal to beginner Pilates
- Vinyasa or power yoga: 300 to 450 calories per hour, comparable to advanced Pilates
- Brisk walking (3.5 mph): about 250 to 350 calories per hour
- Running (6 mph): about 500 to 700 calories per hour
Pilates will never compete with running or cycling on raw calorie burn. But comparing exercises purely on calories per hour misses what Pilates actually does well, which is build lean muscle that changes your body composition over time.
The Muscle and Metabolism Effect
Pilates burns fewer calories during a session than most cardio workouts, but it changes your body in ways that affect how many calories you burn the rest of the day. A study of adult women who did Pilates three times per week for eight weeks found significant increases in skeletal muscle mass, from an average of 21.84 kg to 22.71 kg for mat Pilates and from 21.12 kg to 22.12 kg for apparatus Pilates. That’s roughly a one-kilogram (2.2-pound) gain in lean muscle in just two months.
Muscle tissue burns more calories at rest than fat tissue does. Every pound of muscle you add increases your resting metabolic rate by a small but meaningful amount. Over months and years, that adds up. So while a single Pilates class might burn 200 calories, the muscle you build from consistent practice quietly increases your daily energy expenditure even when you’re sitting at your desk.
Pilates and Body Fat Loss
If your goal is weight loss, the calorie burn during class tells only part of the story. Research on women following an eight-week mat Pilates program found significant decreases in body fat percentage and visceral fat (the deep abdominal fat linked to health risks). Interestingly, overall body weight didn’t change significantly in that study, which makes sense: participants were likely gaining muscle while losing fat, and those shifts can cancel each other out on the scale.
Studies in obese participants have shown more pronounced fat loss after 8 to 12 weeks of mat Pilates, likely because their starting point allows for bigger initial changes. One important finding from the research: when participants stopped training for just three weeks, some of the body composition improvements began to reverse. Consistency matters more than intensity for long-term results.
How to Maximize Your Calorie Burn
If you want to get the most out of each Pilates session in terms of calories, a few adjustments make a real difference. First, progress to harder classes as soon as you’re able. The jump from beginner to intermediate alone can add 50 to 100 calories per hour. Second, choose classes that minimize rest between exercises and keep you moving continuously. Flowing sequences burn more than stop-and-start formats.
Adding resistance, whether through a reformer, resistance bands, or a Pilates ring, forces your muscles to work harder on every repetition. If you only have access to mat classes, focus on exercises that engage your full body rather than isolating small muscle groups. Moves that combine leg work with core engagement and arm involvement recruit more total muscle and drive up energy expenditure.
Finally, pairing Pilates with some form of cardio on alternate days gives you the best of both worlds: the muscle-building and flexibility benefits of Pilates alongside the higher calorie burn of aerobic exercise. Two to three Pilates sessions per week, combined with walking, cycling, or swimming on other days, is a practical approach that supports both fat loss and long-term body composition changes.
