The short answer is yes, Pilates can support weight loss, but not the way running or HIIT does. Pilates is not a high-calorie cardio burner. It helps you lose weight indirectly, by building lean muscle, raising your resting metabolism, improving how your body looks and moves, and keeping you consistent because you actually enjoy it. This guide gives you the honest math: how many calories Pilates burns, what the studies actually found, and how to build a plan that produces real results.
The Honest Answer: Yes, But With Conditions
Pilates contributes to fat loss, but weight loss always comes down to a calorie deficit (burning more than you eat). Pilates helps you reach that deficit in three ways:
- It burns calories during each session (modest, but it adds up).
- It builds lean muscle, which raises the calories you burn at rest.
- It makes a consistent, sustainable routine easier to stick with.
What Pilates will not do is out-train a poor diet. Nutrition drives roughly 70 percent of any weight-loss result. Treat Pilates as the movement engine and your eating as the fuel control.
How Many Calories Does Pilates Burn?
Calorie burn depends on your bodyweight, the intensity, the duration, and whether you are on a mat or a reformer. Here are the figures most consistently reported across research and fitness sources.
|
Session type |
Duration |
Approx. calories burned |
|
Mat Pilates (beginner) |
50 min |
150 to 175 |
|
Mat Pilates (advanced) |
50 min |
250 to 254 |
|
Mat Pilates |
60 min |
175 to 350 |
|
Reformer Pilates |
60 min |
250 to 450 |
|
Reformer (jumpboard or power class) |
60 min |
up to 450+ |
Burn also scales with bodyweight. The heavier you are, the more you burn for the same session.

Pilates sits at roughly 3.2 to 6.7 METs depending on intensity, which is why a vigorous reformer class burns close to a brisk walk or light jog, while a gentle mat class burns less. For a deeper breakdown, see our guide on how many calories Pilates burns.

If your priority is the highest burn per session and you have studio access, reformer wins. If your priority is consistency, low cost, and practicing at home, mat is the smarter starting point. Many people do both. Read more in our comparison of reformer Pilates vs mat Pilates.
What the Research Actually Shows
The studies are encouraging but honest about limits:
- 2017 study, 37 overweight women aged 30 to 50, 8 weeks: Pilates lowered BMI and reduced waist and hip circumference, with visible abdominal toning. Lean mass did not change significantly.
- 2015 study, postmenopausal women, 12 weeks of mat Pilates: strength improved, but body composition did not change, because diet was left unchanged. This is the key lesson: Pilates without nutrition adjustment often shows no scale movement.
- 2016 Journal of Physical Therapy Science, 12 weeks: measurable improvement in body fat percentage and muscle mass.
- 2021 meta-analysis: Pilates alone produced about 2.1 lb of loss over 12 weeks, while Pilates combined with aerobic exercise produced about 7.3 lb.
The pattern is clear. Pilates reliably reshapes and tones. It only moves the scale meaningfully when paired with a calorie deficit and ideally some cardio.
How Pilates Supports Weight Loss (The Mechanisms)
- Builds lean muscle. More muscle raises your resting metabolic rate, so you burn more even on rest days.
- The Pilates effect. Better posture and a stronger, tighter core make you look leaner and more defined, often before the scale changes.
- Adherence. Low impact and enjoyable means you keep showing up, and consistency beats intensity over months.
- Stress and sleep. Pilates lowers cortisol and improves sleep, which curbs the stress eating that quietly derails most diets.
A Realistic Plan and Timeline
For weight loss, frequency matters more than any single hard session.
- Beginners: 2 to 3 sessions per week, 30 to 45 minutes.
- For weight loss: 3 to 5 sessions per week, 30 to 60 minutes, combined with cardio and strength.
- Pair it: 2 to 3 Pilates sessions plus 2 cardio sessions (walking, running, cycling) per week.
A sample week might look like: Pilates Monday, cardio Tuesday, Pilates Wednesday, rest Thursday, reformer or strength Friday, cardio Saturday, rest Sunday.
Realistic results: core and posture changes in 2 to 3 weeks, visible body changes in 2 to 3 months. Pilates alone, with a modest calorie deficit, can produce around 0.5 to 1 kg of loss per month. That is sustainable, not dramatic, and it tends to stay off.
To get started at home, work through our beginner’s guide to Pilates and these equipment-free Pilates exercises. Then support the burn with cardio workouts and a high-protein diet to protect muscle while you lose fat.
Five Beginner Pilates Moves That Support Fat Loss
- The Hundred: core activation and circulation, the classic warm-up.
- Criss Cross: targets the obliques and deep core.
- Plank: full-body tension, builds the metabolically active muscle.
- Scissor: core control plus hamstring and hip work.
- Side Leg Series: glutes and outer thigh, shaping the lower body.

Who Should Be Cautious
Check with a doctor before starting if you have an active back injury, knee problems, are pregnant, or have arthritis. Pilates is generally safe and low impact, but form matters, especially under fatigue.
What to Wear for Pilates
Pilates involves a lot of rolling, inversions, and precise movement, so you want pieces that move with you and stay put. Choose fitted, breathable yoga and Pilates wear, squat-proof leggings with a secure waistband, and a supportive top from the women’s training collection. See our guide on how to choose the perfect Pilates outfit.
Frequently Asked Questions
Can Pilates alone help me lose weight?
It can produce slow, steady loss when paired with a calorie deficit, but the results are modest. Combine it with cardio and a controlled diet for meaningful weight loss.
Does Pilates burn belly fat?
You cannot spot-reduce fat, but Pilates strengthens and tones the abdominal muscles, and overall fat loss (from a deficit) reveals that definition.
How long until I see results?
Core and posture changes in 2 to 3 weeks, visible body changes in 2 to 3 months with consistency.
Mat or reformer for weight loss?
Reformer burns more per session, but mat is cheaper and easier to stay consistent with. Consistency wins long term.
Is Pilates better than yoga for weight loss?
Pilates is generally more strength and core focused, so it can edge out gentle yoga for calorie burn, but neither replaces cardio. See our Pilates vs yoga comparison.
