Pilates has become the next big thing in the wellness and fitness world. With studios opening left, right, and centre, and a range of options to participate in, from mat Pilates, reformer Pilates, hot Pilates, home Pilates, and so on, there’s an option for everyone. For those who’ve always wanted to get into resistance training but never really enjoyed the gym or weights, Pilates seems like the perfect in-between. With that in mind, you may wonder if Pilates can be an effective and equivalent option to the gym. This article outlines everything you need to know about both, providing a clear understanding. Continue reading below to learn how to make an informed decision based on your goals, preferences, needs, and individual circumstances.
While both Pilates and gym-based resistance training can improve strength, posture, and body composition, their outcomes and mechanisms differ (1,2,3). This will be particularly obvious when training is consistently maintained and adhered to over a longer period.
Key distinctions based on current evidence:
Ultimately, the difference isn’t just about body shape, it’s about what each method tends to focus on. Gym-based training typically prioritizes progressive overload, heavier lifts, and full-body strength, although there are various ways to structure a gym program based on your specific goals.
On the other hand, Pilates places more emphasis on alignment, core control, and mindful movement. Both offer powerful benefits, physically and mentally, and can support strength, mobility, posture, and overall well-being in various ways.
There’s no one-size-fits-all “Pilates body” or “gym body”, it’s merely just different results shaped by consistency, personal preference, and what feels right for you.

Whether Pilates can replace the gym will depend on your goals, preferences, and how your sessions are structured.
From a health perspective, the World Health Organization’s general physical activity guidelines are recommended as (11):
• At least 150 minutes of moderate-intensity aerobic activity per week.
• Plus 2 or more days of full-body muscle-strengthening activity.
Some Pilates styles, particularly those that use resistance, can meet these strength guidelines if they’re challenging enough and applied progressively.
However, many traditional Pilates classes are lower-load and focus more on mobility, posture, and core endurance. In that case, you may still benefit from combining Pilates with other strength or aerobic training for a more well-rounded routine.

Firstly, it’s important to note that all bodies are good bodies. You don’t need to earn the status or description for this, and it certainly isn’t defined by a specific size or appearance. What truly matters is how you feel in your body and how your body can function.
Ideally, your body should feel strong, supported, and free from pain or limitations, allowing you to live a fulfilling, independent life with high-quality movement and energy.
The World Health Organization (WHO) defines health as “a state of complete physical, mental, and social well-being – not merely the absence of disease or infirmity” (12).
Pilates can absolutely support that vision. It can enhance strength, posture, mobility, and overall body awareness. Many people experience improved muscle tone, endurance, and functional movement as a result of regular practice.
However, when it comes to visible changes in body composition (such as fat loss), these are primarily influenced by your overall energy balance – that is, burning more energy than you consume over time. Pilates can be a powerful part of that process, particularly when it’s combined with good nutrition, recovery, and consistent daily movement (13).
So, in short, while Pilates can help you build a strong, capable, and confident body, the definition of a “good” body should always come back to how it supports your life, not how it looks.
Our previous post goes into great detail about the Pilates transformation.
Pilates alone won’t drastically change your body shape on its own, but it can support noticeable improvements in posture, core strength, muscle tone, and body composition over time.
Here’s how Pilates contributes to these changes:
Pilates helps sculpt rather than bulk, and may create a longer, leaner look. However, if your goal is significant fat loss or muscle growth, you’ll want to combine it with resistance training and a well-planned nutrition plan (14,15).

While both Pilates and gym-based training can enhance strength, posture, and overall body composition, they achieve this through distinct approaches. Gym training typically focuses on progressive overload – lifting heavier weights over time to build muscle mass, boost metabolism, and prevent age-related muscle loss (sarcopenia). It’s particularly effective for improving long-term strength and body composition.
On the other hand, Pilates emphasizes core control, alignment, mobility, and body awareness. It’s beneficial for improving posture, flexibility, and functional movement, and may reduce back pain or fall risk in older adults. Pilates can lead to a leaner, more balanced look, but results are usually more modest unless paired with regular aerobic activity and dietary adjustments (16).
There’s no single “Pilates body” or “gym body”. Both offer unique benefits, and the best choice depends on your personal goals, preferences, and what keeps you consistent.

Pilates can improve strength, posture, and mobility, but for bone density, muscle mass, and heart health, adding resistance or cardio is recommended, depending on your goals. Not always. However, if your goal is to build significant muscle or strength, traditional resistance training offers greater load and progression than Pilates alone. Pilates can help contribute to both fat loss and muscle building. However, fat loss is a result of a negative energy balance, which is created through burning more energy than you consume through food. Building muscle requires enough volume and adequate protein and carbohydrates. Both can tone your body. Pilates refines posture and deep muscles, while gym training offers more overload and muscle definition. The best choice will depend on your preference and consistency.Frequently Asked Questions
Is Pilates alone enough of a workout?
Do I need to lift weights if I do Pilates?
Does Pilates build muscle or burn fat?
Is Pilates or the gym better for toning?
Both Pilates and gym-based training offer powerful benefits, but they serve slightly different purposes. Pilates emphasizes posture, control, mobility, and deep core strength. It’s a fantastic option for improving alignment, flexibility, and functional movement, particularly for beginners, older adults, or anyone who is recovering from injury.
On the other hand, gym-based strength training offers greater potential for building muscle mass, increasing strength, supporting metabolism, and improving bone density, all of which become even more important with age.
However, the key isn’t just lifting weights, it’s following a progressive program that challenges your muscles to adapt over time, in addition to being consistent with your training routine. Ultimately, the “better” option depends on your body, goals, and lifestyle. For some people, Pilates may be enough, while for others, combining both methods may offer the most balanced benefits. What matters the most is consistency, enjoyment, and choosing something that keeps you moving regularly, because the best plan is one you can stick with in the long term.
