If weight loss is one of your fitness goals, you may be wondering: is reformer Pilates good for weight loss?
The short answer is yes. Reformer Pilates can support weight loss by increasing your physical activity, challenging your muscles, and helping you build a consistent exercise routine. It is not a shortcut for losing body fat, though, and the number of calories burned in a reformer class is only one part of the equation.
Weight loss happens when your body uses more energy than you consume over time. The CDC's guidance on physical activity and weight management explains that physical activity increases the calories your body uses, while reducing calorie intake can help create the calorie deficit needed for weight loss. Exercise also plays an important role in maintaining weight loss over time.
Reformer Pilates can fit into that bigger picture while offering benefits that go far beyond the number on the scale.
Reformer Pilates can be a useful part of a weight-loss plan, but it should not be treated as a stand-alone fat-loss solution.
Research into Pilates and body weight is promising in some populations, although the evidence is still developing. A meta-analysis of 11 randomized controlled trials involving adults with overweight or obesity found that Pilates was associated with decreases in body weight, BMI, and body fat percentage. The researchers also noted that larger, higher-quality studies are still needed.
Research involving healthy adults is less clear. A separate systematic review found that some studies reported improvements in body composition, but the authors concluded that the evidence remained uncertain due to limited research quality and inconsistent findings.
There is another important limitation: much of the research examines Pilates as a broad exercise method rather than reformer Pilates specifically.
The takeaway is that reformer Pilates can contribute to weight loss, especially when practiced consistently alongside appropriate nutrition and other forms of movement. It should not be marketed as a workout that automatically causes weight loss.
The value of reformer Pilates comes from combining resistance, movement, and a workout format that can be adjusted as your strength improves.
Here are four ways it can support your goals:
Pilates also gives you plenty of ways to progress. Exercises can become more challenging by adjusting spring resistance, range of motion, positioning, tempo, and exercise selection.
Flexia's Smart Reformer can even measure weight moved during reformer Pilates, giving you another way to see how the resistance in your workouts changes as you progress.
There is no single reliable number of calories everyone will burn during a reformer Pilates workout.
Your energy expenditure depends on your body size, the exercises being performed, workout duration, rest periods, intensity, and several other factors.
A 2026 systematic review examined the metabolic intensity of Pilates workouts. Across six studies, Pilates averaged about 3.7 METs and 3.8 calories per minute. A more conservative analysis that excluded higher-risk studies produced estimates closer to 3.0 METs and 2.9 calories per minute. The researchers rated the available evidence as low or very low certainty.
Those numbers should not be treated as a reformer calorie calculator. Most of the research involved mat Pilates. Only a small amount of available data examined equipment-based Pilates, although one included study found higher metabolic intensity and energy expenditure on the reformer than during mat Pilates. The researchers described the evidence for the reformer as preliminary.
The better approach is to view calorie burn as one benefit of your workout rather than its only measure of success.
Weight loss and improved body composition are not always the same thing.
The scale measures total body weight. It does not tell you how strong you are, how well you move, or whether your fitness has improved.
Reformer Pilates uses spring resistance to challenge your muscles through controlled movements. You can gradually adjust the exercises as your strength and skill improve. Flexia's guide to adjusting spring resistance during reformer Pilates explains how changing springs can provide either additional resistance or additional support, depending on the exercise.
Core training is also built into much of a reformer workout. Exercises such as planks, Elephant, and Long Stretch challenge your trunk while recruiting muscles throughout the rest of your body. Try these reformer core exercises to see how full-body Pilates movements can challenge your core.
Building strength is valuable even when changes on the scale happen slowly.
Reformer Pilates can strengthen your abdominal muscles, but you should not expect ab exercises to determine exactly where your body loses fat.
A systematic review and meta-analysis examining localized fat loss found no meaningful spot-reduction effect across 13 studies and 1,158 participants.
Individual studies have produced different results, so research on spot reduction continues to evolve. The practical advice remains the same: do not depend on hundreds of abdominal exercises to selectively remove stomach fat.
Reformer Pilates can help you build a stronger core while your broader nutrition and exercise habits influence changes in overall body fat.
That distinction matters. Stronger abdominal muscles may change how your body performs and feels, even before you see a major change on the scale.
Reformer Pilates and cardiovascular exercise offer different benefits, and you do not have to choose only one.
Activities such as brisk walking, cycling, swimming, and running can make it easier to accumulate aerobic exercise throughout the week. Reformer Pilates adds resistance training, mobility work, coordination, and core-focused movement.
Federal physical activity guidelines recommend that adults aim for at least 150 minutes of moderate-intensity aerobic activity each week, along with muscle-strengthening activities on at least two days. More activity can provide additional health benefits.
Your reformer can also incorporate more cardiovascular work. A Pilates jumpboard lets you perform low-impact jumping exercises while lying on the reformer, adding a new type of movement to your Pilates routine.
A balanced routine could include reformer Pilates, walking, cycling, swimming, or another activity you enjoy, rather than trying to find one exercise that does everything.
Consistency matters more than finding a supposedly perfect weight-loss workout.
If reformer Pilates is going to be part of your routine, focus on building habits that you can maintain.
Flexia's smart technology can help with the last point. The reformer tracks Control, Speed, and Consistency during supported classes, enabling you to use Pilates metrics to track your practice rather than relying solely on body weight.
There is no universal number of reformer classes required to lose weight.
Your results depend on your total activity, nutrition, workout intensity, starting point, and individual goals.
For many people, two or three reformer sessions each week can fit comfortably into a broader fitness routine. You can combine those workouts with walking or other cardiovascular activity to work toward recommended weekly activity levels.
Beginners do not need to jump straight into advanced classes. Starting with manageable sessions can give you time to learn the movements, improve your control, and build a sustainable routine.
Even a short session can contribute to your weekly activity. Flexia's 10-minute full-body Pilates workout is one option for days when a full class does not fit your schedule.
Weight loss is one possible outcome of a consistent reformer practice, but it should not be the only way you judge whether Pilates is working.
Yes, reformer Pilates can contribute to weight loss. Physical activity increases energy expenditure, and Pilates may also help you build strength and maintain a consistent exercise routine.
Your results will depend on your overall energy balance and lifestyle, not on Pilates alone.
Reformer Pilates can provide strength, mobility, and some cardiovascular demand, but a varied exercise routine has advantages.
Current physical activity recommendations include both aerobic and muscle-strengthening activity. Combining reformer sessions with walking, cycling, swimming, or another cardiovascular activity can help you build a more complete routine.
There is no fixed timeline because results can mean several different things.
You may notice improvements in coordination, control, mobility, or strength before your body weight changes. Changes in body composition depend on factors including training consistency, nutrition, activity level, and your starting point.
There is not enough high-quality research to provide a universal answer.
One study included in a recent systematic review found greater metabolic intensity and energy expenditure during reformer Pilates than mat Pilates, but researchers cautioned that evidence comparing the two formats is limited.
Reformer Pilates can support weight loss, but some of its most useful benefits have nothing to do with the scale.
A consistent practice can help you develop strength, control, mobility, and confidence in how your body moves. Those improvements can make it easier to stay active and build a fitness routine that lasts.
If weight loss is your goal, think of reformer Pilates as one part of the plan. Combine regular movement with nutrition habits that support your goals, include aerobic activity where appropriate, and measure progress in more ways than pounds lost.
Most importantly, choose a movement you are willing to keep doing. A sustainable Pilates practice can contribute far more to your long-term health than a short-lived attempt to burn as many calories as possible in every workout.
