Does Reformer Pilates Help With Weight Loss?
Reformer pilates can be a helpful part of a weight loss programme, but it works best when combined with dietary changes and other forms of exercise. It builds lean muscle, increases calorie burn, and improves body composition — all of which support weight management. However, weight loss ultimately depends on creating a calorie deficit through a combination of reduced-calorie diet and regular physical activity. In the UK, the NHS recommends losing weight at a rate of 0.5 to 1 kg per week for sustainable results. Reformer pilates alone is unlikely to achieve this, but as part of a structured weight loss approach, it can make a meaningful difference to your health and fitness.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
How Reformer Pilates Supports Weight Loss
Reformer pilates is a low-impact exercise that uses a specialised machine to build strength and endurance. It offers several benefits for weight management:
- Muscle building: Pilates creates lean muscle mass, which increases resting metabolic rate — meaning you burn more calories at rest
- Calorie expenditure: A typical reformer pilates class burns approximately 200–400 calories per hour, depending on intensity and body composition
- Improved body composition: Even if the scale doesn't change significantly, pilates can improve muscle-to-fat ratio, making you look and feel leaner
- Core strength: Pilates specifically targets core muscles, which supports better posture and can reduce injury risk during other exercise
- Consistency: Low-impact exercise is easier to sustain long-term, supporting adherence to a fitness routine
However, reformer pilates is primarily a strength and flexibility tool rather than a high-intensity cardio workout. For meaningful weight loss, it should be combined with other forms of exercise and a calorie-controlled diet.

Combining Pilates With Other Weight Loss Methods
For effective weight loss in the UK, evidence supports combining multiple approaches: dietary changes (aiming for a calorie deficit of around 500 kcal per day), regular aerobic exercise, and strength training like reformer pilates. This multi-faceted approach typically produces better results than any single method alone. Some people also benefit from working with their GP or a weight management specialist, particularly if they have weight-related health conditions such as type 2 diabetes or high blood pressure. NHS weight management services offer structured programmes, and for eligible adults, prescription weight loss medications (such as GLP-1 injections) may be recommended alongside lifestyle changes. Your GP can discuss whether this is appropriate for you. Use our free BMI calculator to check your current health status, and our GLP-1 weight loss calculator to explore how different approaches might support your goals.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How many calories does reformer pilates burn?
A typical reformer pilates class burns approximately 200–400 calories per hour, depending on your body weight, fitness level, and class intensity. For comparison, jogging burns around 400–600 calories per hour. Reformer pilates is effective for building muscle and supporting weight loss as part of a combined approach, but higher-intensity cardio burns more calories per session.
Can reformer pilates alone help me lose weight?
Reformer pilates alone is unlikely to produce significant weight loss without dietary changes. Weight loss requires a calorie deficit, which comes from eating less and moving more. Pilates is excellent for building strength and improving body composition, but it works best combined with aerobic exercise and a reduced-calorie diet. The NHS recommends 0.5–1 kg per week as a sustainable loss rate.
How often should I do reformer pilates for weight loss?
For weight loss benefits, aim for 2–3 reformer pilates sessions per week, combined with 150 minutes of moderate aerobic exercise weekly (such as brisk walking or cycling). This combination of strength and cardio, alongside a calorie-controlled diet, is most effective. Always allow at least one rest day per week for recovery.
Is reformer pilates suitable for all fitness levels?
Yes, reformer pilates is low-impact and can be adapted for different fitness levels. This makes it accessible for people with joint issues or those returning to exercise after time off. However, if you have any health concerns or existing conditions, consult your GP before starting a new exercise programme to ensure it's safe for you.
What's the difference between reformer pilates and mat pilates for weight loss?
Reformer pilates typically burns slightly more calories because the machine adds resistance, but both forms build lean muscle and support weight loss when combined with diet and other exercise. Mat pilates is cheaper and more accessible, while reformer classes offer more structured progression. Choose whichever you'll stick with consistently — adherence matters more than the specific type.
