If you have ever watched a Pilates class from the outside, it is easy to understand where the misconception comes from.
People are moving slowly.
There are long, controlled movements.
Someone may have a leg extended toward the ceiling.
Another person is lying on a Reformer while the carriage quietly slides backwards and forwards.
It can look a little like an elaborate stretching session.
But no — Pilates is not just stretching.
The good news is that Pilates can improve flexibility and mobility, but those are only part of what you may be training.
Depending on the exercises, equipment and programming, Pilates can also challenge muscular strength and endurance, trunk control, balance, coordination and your ability to control movement through different ranges.
And if you have ever looked at a Pilates exercise and thought, “That doesn’t look very hard,” there is a good chance it feels rather different from how it looks.
Is Pilates Just Stretching?
No. Pilates is a form of exercise that combines controlled movement with muscular effort, coordination and breathing, and it can also incorporate flexibility and mobility work.
Some Pilates exercises genuinely do stretch muscles or move joints through larger ranges.
Others require you to support your own body weight, resist springs, control a moving carriage, hold a position, move slowly against resistance or stop one part of your body moving while another part does.
Those are not simply stretching tasks.
The Australian Government-funded Healthdirect guide to Pilates describes Pilates as exercise based on controlled movement and breathing that can improve strength, balance and flexibility. It also notes that Reformer equipment uses springs to provide resistance.
So if the only thing stopping you from trying Pilates is the thought that you could achieve the same thing by stretching on your lounge-room floor for ten minutes, the two are not equivalent.
Why Does Pilates Look Like Stretching?
Part of the confusion is visual.
Traditional strength training is easy to recognise.
Someone picks up a dumbbell.
Someone loads a bar.
Someone pushes a machine.
We can see the resistance.
In Pilates, the challenge is not always so obvious.
Resistance can come from your own body weight, gravity, the position of your limbs, the length of a lever, springs, straps, unstable or moving equipment, or simply controlling a movement slowly and precisely.
At the same time, many Pilates exercises take the hips, shoulders and spine through useful ranges of motion.
That combination of slow movement + long ranges + controlled positions can make Pilates look like stretching even while muscles are working hard.
Controlled does not mean effortless.
What Is the Difference Between Stretching and Pilates?
Stretching generally involves lengthening tissues or moving a joint into a position intended to maintain or improve range of motion.
Pilates is broader than that.
You may move through a large range while simultaneously creating force and controlling your body.
Imagine lifting one leg toward the ceiling.
That position might create a stretch through the back of your thigh.
But if you are also controlling your pelvis, supporting the weight of your leg and deliberately moving through the range, other muscles are working at the same time.
Likewise, a Reformer exercise may look beautifully fluid while your legs are actively controlling spring resistance in both directions.
So Pilates does not neatly fit into a box labelled stretching.
Nor does every Pilates exercise have exactly the same training purpose.
Does Pilates Improve Flexibility?
It can.
And that is a benefit, not evidence that Pilates is “only stretching.”
Many Pilates movements take joints through controlled ranges and can expose muscles to positions that require flexibility and mobility.
A 2022 systematic review comparing Pilates with other forms of exercise examined outcomes including muscular strength, balance and flexibility. The authors found low to very-low-certainty evidence suggesting Pilates produced broadly similar outcomes to other exercise modalities across those measures rather than being uniquely superior.
Read the systematic review: Is Pilates Better Than Other Exercises at Increasing Muscle Strength?
That is actually a useful finding.
We do not need to claim Pilates is magically better than every other exercise to recognise that it can be a legitimate way to train several aspects of physical fitness.
Do You Have to Be Flexible to Do Pilates?
No.
You do not need to arrive flexible enough to touch your toes, put your leg behind your head or fold yourself neatly in half.
Exercises can be changed to suit your current range.
A smaller controlled movement is still a movement.
Your range may change with practice, but flexibility is not an entry requirement.
This is one of the reasons Pilates can be approachable for women who have spent years saying, “I’d love to try it, but I’m just not flexible.”
You start with the body you have today.
If you’re completely new, our Pilates for Beginners guide explains what to expect from your first class and what you actually need to bring.
Does Pilates Build Strength?
Yes, Pilates can challenge and improve muscular strength and endurance.
But this needs a little more explanation than simply calling Pilates “strength training” and moving on.
Muscles respond to the demands placed on them.
If an exercise asks a muscle to produce enough force to make the task challenging, that muscle is doing meaningful work.
In Pilates, the challenge may come from:
- supporting your own body weight
- working against spring resistance
- controlling a movement slowly
- holding a position
- moving with a long lever
- performing repeated contractions
- resisting rotation or unwanted movement
- controlling the return phase of an exercise
This can absolutely create muscular challenge.
However, the amount of resistance and progression matters.
A gentle beginner exercise and a heavily challenged advanced exercise are not identical training stimuli simply because both are called Pilates.
Another way to increase the resistance challenge is to incorporate light external loads into selected exercises. If you’re curious about how this changes the workout, read our guide to Pilates with weights, including when dumbbells can be useful and when traditional Pilates may be enough.
What Does the Research Say About Pilates and Strength?
A systematic review published in 2022 analysed randomised controlled trials comparing Pilates with other forms of exercise for muscular strength.
Across the included studies, the researchers did not find convincing evidence that Pilates was superior to other exercise for dynamic strength, isometric strength or strength endurance.
But that does not mean Pilates failed to challenge strength.
The conclusion was that there was low to very-low-certainty evidence of no meaningful difference between Pilates and the comparison exercise modalities for those outcomes.
A broader 2023 umbrella review examined 27 systematic reviews covering multiple health outcomes associated with Pilates. It found promising effects across several outcomes, while also noting that much of the evidence ranged from very low to moderate certainty.
Read the umbrella review of Pilates and health outcomes
That is the kind of evidence-informed position we take at Bodi Boutique.
Pilates has value without needing exaggerated promises.
Is Reformer Pilates Just Stretching?
Definitely not.
Reformer Pilates introduces a piece of equipment with a moving carriage, springs, straps, a footbar and other components that can change the mechanical demands of an exercise.
The springs are particularly important.
But there is another Pilates myth hiding here:
more spring does not always mean harder.
Depending on the exercise, springs can create resistance, provide assistance or change how much control is required to manage the moving carriage.
For example, increasing spring resistance during one leg exercise may make pushing the carriage away more demanding.
In another exercise, stronger springs may actually provide more support.
This is one of the things that makes Reformer Pilates so versatile.
It is not simply a stretching bed with straps attached to it.
If you’re wondering what all the equipment actually does, read What Is Reformer Pilates? How It Works, Benefits & What to Expect.
Why Can Light Reformer Springs Sometimes Feel Harder?
This is one of the most surprising things for beginners.
You assume that fewer or lighter springs must automatically make an exercise easier.
Then your instructor changes the springs and suddenly everything starts shaking.
Why?
Because the spring is not only providing resistance.
It can also influence how supported and stable the carriage feels.
In some exercises, reducing spring assistance means your body has to contribute more control.
The exercise has changed.
That does not mean lighter springs are universally harder either.
The effect depends on the exercise, direction of force, body position and intended challenge.
This is why simply counting springs tells you surprisingly little about how difficult a Reformer session actually is.
Why Does Pilates Feel Hard if the Movements Are So Slow?
Speed is not the only thing that makes exercise demanding.
Slow movement can require you to maintain tension and control for longer.
You cannot always rely on momentum to get you through the difficult part.
And when an instructor asks you to move slowly while keeping the rest of your body controlled, suddenly a very innocent-looking movement can become rather demanding.
Then there are holds.
Then pulses.
Then long levers.
Then springs.
Then your instructor calmly says, “Four more.”
And you begin questioning whether she understands mathematics.
Pilates can look graceful while feeling anything but easy.
Why Do Your Muscles Shake During Pilates?
If Pilates were merely passive stretching, the famous Pilates shake would be rather difficult to explain.
Muscle trembling can occur when an exercise becomes demanding or fatigue develops.
That does not mean shaking is required for a workout to be effective, nor does it prove that a particular “deep” muscle has suddenly switched on.
But it is one indication that the exercise may be placing a meaningful demand on your neuromuscular system.
We have an entire evidence-based guide explaining why muscles shake during Pilates and when you should keep going, modify or rest.
Is Pilates a Proper Workout?
Yes — but “workout” is a very broad term.
A workout does not have to leave you breathless, dripping in sweat or unable to walk downstairs the next morning to count.
Different exercise sessions train different qualities.
A Pilates class may challenge strength, muscular endurance, balance, mobility, coordination and movement control.
Depending on how it is programmed, it may be gentle or quite demanding.
What it does not automatically provide is every element of fitness in one perfect package.
For example, a Pilates class may not create the same cardiovascular stimulus as running, cycling or a vigorous group fitness session.
And a particular Pilates program may not provide enough resistance to maximise someone’s strength or muscle-building potential.
That does not make Pilates ineffective.
It means exercise should match your goals.
Does Pilates Count as Strength Training?
Sometimes, yes — but the quality and intensity of the program matter.
There is no magical rule that says resistance must come from a dumbbell before your muscles notice it.
Body weight and springs can provide resistance.
However, if strength is a major goal, the exercises need to become sufficiently challenging and ideally progress over time.
Pilates can contribute to strength training, but whether it can completely replace traditional resistance exercise depends on your goals, current strength and how your program progresses. Read our full guide to whether Pilates can replace weight training.
For now, the important takeaway is that Pilates can contribute to strength training, but you should not assume every Pilates class automatically provides all the progressive resistance you may want for every muscle group.
Is Pilates Enough Exercise on Its Own?
That depends on what your Pilates looks like and what you mean by “enough.”
Australia’s updated 2026 movement guidelines recommend that adults regularly perform different kinds of physical activity, including moderate-to-vigorous activity, muscle-strengthening work and activities targeting mobility, balance and coordination.
For adults, the recommendations include muscle-strengthening activities involving the major muscle groups on at least two days each week.
Read Australia’s current physical activity recommendations for adults
Pilates can overlap with several of those categories.
But a balanced exercise routine may still include other forms of movement depending on your goals, preferences and current program.
You might combine Pilates with walking.
Or traditional resistance training.
Or group fitness.
Or running.
Or all of the above across a week.
You do not need one exercise modality to do everything.
Is Pilates Worth Doing for Women in Their 40s, 50s and 60s?
Absolutely — provided the exercises and level are appropriate for you.
As we get older, there is good reason to care about more than simply how many calories a workout burns.
Strength matters.
Balance matters.
Mobility matters.
Coordination matters.
And being able to confidently get up, move, carry things, travel, exercise and participate in everyday life matters.
Pilates can train several of these physical qualities at once.
Research in adults aged 60 and over has found improvements in measures including strength, balance, flexibility and physical function when Pilates was compared with inactive control conditions, although study quality and methods vary.
Read the systematic review and meta-analysis of Pilates in older adults
Another meta-analysis of adults aged 55 and over reported improvements across physiological measures that included strength, balance, endurance, flexibility, gait and physical functioning, while also noting substantial variation among the included studies.
Read the meta-analysis of Pilates in adults aged 55 and over
That does not mean every woman needs to wait until she is older before thinking about these things.
Building physical capacity now is worthwhile too.
But Should Women Still Lift Weights?
Pilates and weight training do not need to be enemies competing for your loyalty.
They can complement each other extremely well.
Traditional resistance training makes it relatively straightforward to progressively increase external load.
Pilates can add different challenges involving controlled movement, trunk function, coordination, range and body awareness.
Some women love Pilates and weights.
Some prefer Pilates alongside group fitness.
Others use Pilates as their starting point before gradually adding other forms of exercise.
The right mix depends on your goals and, importantly, what you’re actually willing to keep doing.
A theoretically perfect exercise program that you hate is unlikely to become a very useful long-term routine.
Will Pilates Tone Your Body?
“Toning” is one of those fitness words everyone understands until you try to define it scientifically.
Usually, when someone says she wants to look more toned, she means she wants some combination of greater muscle definition and less body fat covering that muscle.
Pilates can train muscles.
But it cannot selectively remove fat from one part of your body.
Nor does performing hundreds of abdominal exercises specifically burn fat from your stomach.
If changing your waistline is one of your goals, read our evidence-based guide to whether Pilates burns belly fat and how it can support your waistline.
And for the bigger picture, we have also covered whether Pilates is good for weight loss.
Does Pilates Work Your Core?
Many Pilates exercises place substantial demands on the muscles around your trunk.
But “working your core” does not simply mean sucking your stomach inward for an entire class.
Your trunk muscles need to respond differently depending on the movement.
Sometimes you need subtle control.
Sometimes you need a much stronger brace.
Sometimes the challenge is resisting movement while your arms or legs are moving.
We’ve unpacked that in our guide to what “engage your core” actually means and how it should feel.
Mat Pilates vs Reformer Pilates: Is One More of a Workout?
Both can be challenging.
They simply create challenge differently.
Mat Pilates uses gravity and your body weight as major sources of resistance, sometimes with small equipment.
Reformer Pilates adds springs, straps and a moving carriage that can create, reduce or change resistance and stability demands.
A difficult Mat Pilates class can be considerably harder than an easy Reformer class.
And a well-programmed Reformer session can be extremely challenging.
The equipment does not automatically determine the quality or difficulty of the workout.
Programming matters.
For a full comparison, read Mat Pilates vs Reformer Pilates: Which Is Better for You?
Does Pilates Burn Calories?
Of course.
Your body uses energy to perform Pilates just as it does during other physical activity.
But calorie burn is a poor way to judge the total value of an exercise session.
A session that helps you build strength, improve balance or become more capable does not become worthless because your watch displays a smaller calorie number than it did after a run.
Likewise, a high calorie number does not automatically make one workout superior.
Different forms of exercise contribute different things.
Why Pilates Can Be a Good Starting Point if You Haven’t Exercised for Years
If it has been a long time since you exercised regularly, jumping straight into an intimidating high-intensity program can feel like an enormous leap.
Pilates can give you somewhere to begin.
You can learn movements.
Build confidence.
Develop strength and control.
Gradually increase difficulty.
And begin trusting your body again.
That does not mean Pilates must always remain gentle.
A beginner program should look different from what the same person is capable of months or years later.
Your Pilates can grow with you.
Can Pilates Become Too Easy?
Yes.
Any exercise program can stop providing enough challenge if it never progresses.
If you perform exactly the same easy exercises with exactly the same demand forever, your body has little reason to keep adapting.
Progression in Pilates can come from many places.
You can alter resistance.
Change leverage.
Increase range where appropriate.
Improve control.
Add repetitions.
Use more complex movement patterns.
Reduce assistance.
Or progress to a more demanding exercise.
This is another reason skilled programming matters.
The goal is not to make every class brutally hard.
It is to provide an appropriate challenge for the person doing it.
So What Does Pilates Actually Do to Your Body?
There is no single outcome that captures Pilates.
Depending on the type of Pilates you practise and how it is programmed, it may help you:
- challenge muscular strength and endurance
- improve balance and coordination
- move through and control different ranges of motion
- develop trunk strength and control
- improve flexibility or mobility
- become more aware of how you move
- build confidence with exercise
- add varied resistance and movement to your weekly routine
Not every class will train all of these equally.
And Pilates does not need to outperform every other form of exercise to be valuable.
It simply needs to contribute meaningfully to the goals you care about.
What Does the Research Actually Tell Us?
Pilates research is growing, but it is worth keeping the conclusions in perspective.
A 2022 systematic review of randomised controlled studies comparing Pilates with other exercise modalities found low to very-low-certainty evidence of no significant difference between Pilates and other exercise for dynamic strength, isometric strength, strength endurance, balance or flexibility.
Pinto et al. — Pilates compared with other exercise for muscular strength, balance and flexibility
A 2023 umbrella review of 27 systematic reviews found promising associations between Pilates and a variety of health outcomes but rated the certainty of evidence from very low to moderate, highlighting the need for higher-quality research.
Yang et al. — Pilates and multiple health outcomes: an umbrella review
For older adults, a systematic review and meta-analysis of 39 studies reported favourable effects on strength, balance, flexibility and physical function compared with habitual activity or non-exercise controls.
Pilates and physical performance in older adults
And Australian Healthdirect describes Pilates as controlled exercise that can contribute to strength, balance, flexibility and posture — considerably broader than simply stretching.
Healthdirect Australia — Health benefits of yoga and Pilates
The evidence does not tell us that Pilates is a miracle exercise.
It tells us something much more believable:
Pilates can be a legitimate and adaptable form of exercise that trains several important physical qualities.
The Good News: You Don’t Have to Choose Between Strong and Flexible
One of the reasons the “Pilates is just stretching” misconception is so unhelpful is that it treats strength and mobility as though you must choose one.
You don’t.
Being strong through useful ranges of motion is valuable.
Having mobility you can actually control is valuable.
Maintaining balance, coordination and confidence in your movement is valuable.
Pilates can bring several of these qualities together within the same session.
Stretching can be part of Pilates.
It just isn’t the whole story.
What We Teach at Bodi Boutique
At Bodi Boutique, Pilates isn’t about lying on a mat doing a few stretches and going home.
We teach movement progressively so that you can learn the foundations, improve your control and continue to challenge your body as your ability develops.
Some exercises feel beautifully mobile and fluid.
Some ask for precision.
Some require strength.
And some make you wonder why something that looked so easy suddenly has your legs shaking.
That’s part of the variety.
We also don’t believe every woman needs to arrive already fit, flexible or confident.
You begin where you are.
Then we build from there.
