Can Pilates Replace Weightlifting?

Pilates has become the answer to practically everything. Want abs? Pilates. Better posture? Pilates. Want to build muscle without getting bulky? Apparently, Pilates has discovered a special kind of muscle that dumbbells haven’t called the long, lean muscle.

Well, I’ve got bad news for the marketing department.

Your muscles respond to resistance, effort and progression. They don’t know whether that resistance comes from a reformer spring, a cable machine or a barbell.

That’s why I don’t dismiss Pilates. It can be challenging, and people can get stronger doing it.

But Pilates for weightlifting only makes sense when we understand what the two activities actually train.

I’ve spent more than twenty years coaching people in New York, and my approach has always been the same: 

Identify the goal, select the right stimulus, and measure whether it’s working.

So, can Pilates replace lifting? Can it build muscle? And where does it fit if you only have three hours a week to train? Let’s get into it.

Is Pilates Strength Training?

Yes, Pilates can count as strength training. Mat and reformer exercises challenge muscles using body weight, leverage and spring resistance. A Pilates session provides meaningful strength work when the exercises are sufficiently demanding for the muscles involved, rather than simply providing movement or stretching.

The CDC recommends muscle-strengthening activity at least twice weekly, covering all major muscle groups.

A challenging Pilates program or 1-1 session can contribute to that requirement. A gentle, mobility-focused class may not.

For example, a demanding single-leg reformer exercise may provide useful resistance for your legs. A class devoted mainly to breathing and controlled stretching serves a different purpose.

Both can be worthwhile. Just don’t confuse their training effects.

Is Pilates Strength Training or Cardio?

Pilates primarily emphasizes controlled movement, muscular endurance and flexibility, although individual exercises can provide substantial resistance.

Some classes elevate your heart rate, but that doesn’t establish that they deliver enough sustained aerobic activity to improve cardiovascular fitness.

If you’re using Pilates as your main exercise, check whether your routine also includes sufficient aerobic activity and resistance work for all major muscle groups.

Pilates vs. Weight Training: Which Is Better?

Weight training is generally more practical for maximizing muscle size and strength because resistance can be measured and progressively increased.

Pilates can develop strength and flexibility, but its benefits depend on the exercise and training difficulty. The better choice is the one that provides the stimulus needed for your specific goal.

Here’s how the two approaches compare.

Pilates vs. Weightlifting: Head-to-Head Comparison

Training outcome	Pilates	Progressive weight training
General strength	Can improve strength when exercises are sufficiently challenging	Strong evidence across different populations
Maximal strength	Less specific to generating force against very heavy loads	More direct, especially with heavier resistance
Muscle growth	Possible, but direct long-term hypertrophy evidence is limited	Extensive evidence supporting hypertrophy
Muscular endurance	Often emphasized through repeated or sustained movements	Can be developed through suitable training
Flexibility and movement control	Common programming priorities	Can also improve through exercises performed across suitable ranges of motion
Bone health	Bone-density benefits are not well established	Resistance and weight-bearing exercise have established roles in bone health

The American College of Sports Medicine’s 2026 resistance-training position stand synthesized 137 systematic reviews involving more than 30,000 participants.

It found that progressive resistance training improves strength, muscle size, power and several measures of physical function.

The distinction between training goals is important:

• Maximal strength: Heavier loads generally produce greater improvements.
• Muscle growth: Sufficient challenging training volume supports hypertrophy across a range of resistance loads.
• Muscular endurance: Repeated work against resistance can improve the ability to sustain muscular effort.

If you want to increase your squat from 135 to 185 pounds, you need training that progressively develops the strength and skill required for that lift.

Pilates may be useful alongside it, but practicing lighter movements isn’t a replacement for progressing the squat itself.

Does Pilates Build Muscle?

Pilates can provide a muscle-building stimulus when exercises are sufficiently challenging, especially for beginners.

Research demonstrates improvements in certain measures of strength and endurance, but direct evidence for substantial long-term hypertrophy remains limited. For experienced lifters, the practical question is whether Pilates provides enough progressive resistance.

What Does the Latest Research Say?

A 2025 randomized controlled trial examined 47 previously sedentary women aged 30 to 60 with overweight or obesity.

The intervention group performed supervised reformer Pilates three times weekly for eight weeks.

Compared with the inactive control group, participants improved handgrip strength and trunk muscular endurance. Researchers also reported improvements in estimated muscle mass using bioelectrical impedance.

These are useful findings, but the measurements matter.

Handgrip strength is a strength outcome. Trunk endurance measures the ability to sustain muscular work. Bioelectrical impedance estimates body composition rather than directly measuring muscle hypertrophy through imaging.

The study also didn’t compare Pilates against a progressive weightlifting program.

The evidence supports reformer Pilates as a way to improve certain fitness outcomes in previously inactive women. But then anything works if you are a beginner. It doesn’t establish how much muscle experienced lifters can build through Pilates alone.

Does Reformer Pilates Build Muscle?

Reformer Pilates uses adjustable spring resistance, body position and leverage to challenge muscles. That resistance can contribute to muscle growth when an exercise is difficult enough.

Consider a reformer leg press.

If you complete fifteen repetitions and could comfortably perform another twenty, the exercise may not be providing much hypertrophy stimulus at your current strength level.

Increasing spring resistance or choosing a more demanding variation could change that.

But if you can no longer load your legs sufficiently with the available setup, a conventional leg press or squat becomes the more practical option.

The problem is whether the resistance remains challenging enough as you progress.

How Do You Know Whether Pilates Provides Enough Resistance?

I would assess three things:

1. Effort: Are the last repetitions genuinely demanding for the intended muscle? For many hypertrophy-focused exercises, finishing with roughly one to three good repetitions in reserve is a useful practical target.
2. Progression: Can you increase resistance or repetitions while preserving good technique and keeping the intended muscle challenged?
3. Results: Are you progressing on repeatable exercises, or has the workload become easy without a useful way to increase it?

You don’t need to make every movement more complicated. Just make the muscles work sufficiently hard.

If muscle growth is your priority and Pilates no longer provides that challenge, add appropriately loaded strength exercises.

For a more detailed explanation of productive training volume, see my article on how many weekly sets you need to build muscle.

Pilates Body vs. Weight Training Body: Is There a Difference?

Pilates doesn’t create a special type of elongated muscle, and lifting weights doesn’t automatically make women bulky.

What people call a toned appearance generally comes from visible muscle definition. Muscle size, body-fat distribution and genetics influence that appearance.

If you want to build more muscle, prioritize exercises that let you apply sufficient resistance and track your progress.

Your muscles respond to the workload, not the studio’s marketing.

Is Pilates Better for Joint Pain or Bone Health?

Pilates can be a useful exercise option for some people with joint discomfort or movement limitations, but it isn’t inherently safer than weightlifting.

Bone health is a separate issue, where appropriate mechanical loading matters. The best exercise selection depends on the condition, the person’s ability and the outcome being targeted.

Should You Switch From Weightlifting to Pilates if Your Joints Hurt?

Not before identifying what’s causing the discomfort.

Pain may be influenced by exercise selection, load, training volume or an existing injury. Some conditions require medical assessment rather than another workout variation.

If a lift is uncomfortable, there may be useful modifications:

• A supported machine may be more tolerable than an unsupported variation.
• Reducing load or working within a tolerable range of motion may help.
• A different pressing angle may reduce discomfort.
• Temporarily changing training volume may be appropriate when fatigue is contributing.

Pilates is another option, not an automatic solution.

A 2023 systematic review comparing Pilates with other exercise for chronic nonspecific low-back pain examined eleven randomized trials.

It found some evidence favouring Pilates over general exercise for pain reduction, but certainty was low. The authors did not find strong evidence that one exercise method was universally preferable.

For someone managing chronic nonspecific low-back pain, that supports choosing an appropriate, tolerable exercise approach rather than declaring Pilates superior.

Persistent or worsening pain, particularly with neurological symptoms, deserves clinical evaluation.

Is Pilates Enough for Bone Health After 40?

For bone health, I would prioritize a program that includes appropriate resistance and weight-bearing activity rather than rely entirely on Pilates.

Bone responds to mechanical loading, and maintaining muscle strength also supports physical function as we age.

The National Institutes of Health recommends resistance exercise, weight-bearing activity and balance training as components of a bone-health program.

These activities provide different benefits.

Progressive strength exercises help develop muscular force and load the skeleton. Suitable weight-bearing activities provide additional loading. Balance work helps reduce fall risk.

Pilates can contribute movement and balance practice, but its ability to replace a bone-focused loading program hasn’t been established.

For women approaching or experiencing menopause, this distinction becomes particularly relevant because declining estrogen is associated with accelerated bone loss.

That doesn’t mean everyone should start jumping or lifting heavy weights immediately.

Exercise intensity and selection should reflect bone health, training experience and any clinical restrictions. People with osteoporosis or previous fractures may need specific modifications.

Is Pilates Necessary for Flexibility?

No. Pilates can improve flexibility, but appropriately performed resistance training can improve range of motion too, especially if we train with proper range of motion, thereby having a dynamic stretch each time .

A 2023 systematic review of 55 studies found that resistance training with external loads improved joint range of motion. In the pooled comparison, improvements were not significantly different from those achieved through stretching.

That doesn’t make Pilates redundant.

It means you don’t necessarily need a separate flexibility-focused class to improve range of motion if your existing training already addresses the movement limitations that matter to you.

If Pilates helps with a specific goal or you enjoy the variety, keep it.

If you’re moving comfortably and making progress, there’s no reason to add corrective exercises simply because someone says all lifters need them.

Is Pilates or Weight Training Better for Weight Loss?

Neither Pilates nor weightlifting automatically causes fat loss. Both contribute physical activity, but sustained fat loss depends largely on maintaining an appropriate energy balance. Progressive resistance training is particularly useful when you want to lose fat while preserving strength and lean tissue.

The distinction is between losing weight and losing fat.

When you diet, some weight loss may come from fat-free tissue rather than fat alone.

That’s one reason I prioritize resistance training during fat-loss programs.

A 2025 systematic review and meta-analysis examined 25 randomized trials involving adults with overweight or obesity.

Adding resistance exercise to dietary weight loss helped preserve fat-free mass and produced greater fat-mass loss than diet alone.

Those findings support progressive resistance training as part of a weight-loss strategy. They don’t establish a direct comparison with Pilates.

Pilates can still contribute physical activity, improve fitness and help someone maintain a routine they enjoy.

But for someone specifically trying to lose fat without sacrificing muscle, I’d focus first on:

• A sustainable calorie deficit
• Adequate protein intake
• Progressively challenging resistance training
• Regular physical activity and sufficient recovery

Add Pilates when it serves a useful purpose.

Pilates for Weightlifting: How Can It Help Your Lifts?

Pilates may complement weightlifting by providing additional practice with trunk control, coordinated movement and flexibility.

Its usefulness depends on whether those qualities are relevant to your training. Better performance in a Pilates exercise doesn’t automatically produce a stronger squat or deadlift.

I would start by identifying what’s limiting your performance.

Not every lifter needs more flexibility or another core exercise.

And not every movement problem requires Pilates.

If You Want Better Trunk Control

Pilates includes exercises that require you to control the trunk while moving your arms and legs.

That may be useful if coordinated trunk movement is something you want to improve.

But a strong plank or beautifully executed Pilates movement doesn’t guarantee better bracing under a loaded barbell.

You still need to practice maintaining trunk position during the lifts themselves.

I’d use Pilates as supplemental movement practice once a week, not a replacement for specific strength training.

If You Want More Flexibility or Movement Variety

Pilates may give you opportunities to work through movements you don’t regularly practice in the weight room.

That’s useful when those movements support a relevant flexibility or coordination goal but will not magically give a 500 lbs squat or deadlift.

You might already have sufficient range of motion but need better technique or more strength in a particular position.

The solution should match the limitation.

What Pilates Exercises Are Worth Adding?

You don’t need a complicated reformer routine to incorporate Pilates into your training.

Here is an example of a short mat-based session using recognizable Pilates movements.

Pilates exercise	Illustrative starting dose	Main purpose
Single-leg stretch	2 sets of 6–10 repetitions per side	Practice trunk control while alternating leg movement
Shoulder bridge	2 sets of 8–12 repetitions	Controlled hip extension and pelvic movement
Side-kick series	2 sets of 8–12 repetitions per side	Controlled hip movement in a side-lying position
Pilates swimming	2 short sets of controlled alternating movements	Practice trunk and limb coordination

These are examples for someone comfortable performing the movements, not universal prescriptions.

Start with manageable repetitions and a range of motion you can control. Exercises can be modified or omitted according to ability and symptoms.

A Pilates instructor can help refine the movements and choose suitable reformer alternatives.

The point isn’t to master increasingly elaborate exercises.

It’s to identify a movement you want to improve and practice it consistently.

How Much Pilates Should You Do Alongside Weightlifting?

For someone prioritizing muscle and strength, two or three progressive lifting sessions per week are a practical foundation, with Pilates added according to time, goals and recovery.

One Pilates session may be sufficient for supplemental movement practice. More isn’t necessarily better if it reduces the quality of your main training.

The schedule should reflect what you’re trying to accomplish, not what’s hip. Someone training for maximal strength will organize their week differently from someone who mainly enjoys Pilates and wants to remain active.

Pilates and Weight Training Schedule by Goal

Primary goal	Lifting sessions	Pilates sessions	Example schedule
Muscle and strength	3 per week	0–1 optional	Full-body lifting Monday, Wednesday and Friday; optional Pilates Saturday
General fitness	2 per week	1–2	Full-body lifting Tuesday and Friday; Pilates Wednesday
Limited time, about 3 hours	2 per week	0–1 optional	Two focused strength sessions; Pilates if time allows
Pilates as the preferred activity	Add resistance where needed	2–3	Pilates-led week with targeted strength work for undertrained muscle groups

These are illustrative schedules. The appropriate weekly workload depends on training history, goals and recovery.

How Hard Should Your Weightlifting Sessions Be?

If you’re using two full-body sessions per week to build muscle, I’d make sure each workout covers the major movement patterns.

A practical session might include:

• Squat or leg-press variation
• Hip hinge
• Horizontal or vertical press
• Row or pulldown
• One or two targeted accessory exercises

Two or three challenging working sets per exercise can be a reasonable starting point, with total volume adjusted to your experience.

For hypertrophy, you generally want sets that place meaningful demand on the target muscles while preserving good technique.

For many exercises, finishing with approximately one to three repetitions in reserve can be a useful guide.

You don’t need to reach absolute failure on every set.

How Do You Progress Your Training?

Pick a repeatable exercise, record your performance and increase the challenge when you’re ready.

For example, suppose you perform three sets of eight to twelve repetitions with 25-pound dumbbells.

Once you can complete all three sets for twelve controlled repetitions at the intended effort, consider increasing the weight.

Then build back toward the top of the repetition range.

That’s a simple form of double progression.

Pilates can be progressed by changing spring resistance, leverage or repetition demands, provided the intended muscles remain appropriately challenged.

The important part is having a way to measure improvement.

What if You Only Have Two Hours a Week?

If your main objective is building muscle and you can only train twice per week, I’d generally keep both full-body resistance sessions.

Replacing one with a low-resistance Pilates class could substantially reduce the week’s productive strength-training work and hurt your weekly volume.

If you enjoy Pilates, use a shorter session when you have additional time or integrate appropriate exercises as accessories.

But suppose your main goal is general activity, flexibility and enjoying exercise. Then a Pilates-heavy schedule may be a better personal fit, even though I would still put weight training first .

The decision changes because the goal changes.

Frequently Asked Questions About Pilates and Weightlifting

Is Pilates Once a Week Worth Doing if I Already Lift Weights?

Yes. One weekly Pilates session can be worthwhile if you enjoy it or want extra movement practice, flexibility or muscular endurance work. For a lifter already making progress, it isn’t a requirement. Add the class when it serves a specific purpose and doesn’t interfere with your main training or recovery.

Can You Do Pilates and Weight Training on the Same Day?

Yes. You can combine Pilates and weight training on the same day if the workload is manageable. When strength is the priority, do your demanding lifting first. A strenuous Pilates class may fatigue muscles needed for heavy lifts, while a short, easy movement session may work as part of a warm-up.

Is Reformer Pilates Harder Than Mat Pilates?

Not necessarily. Reformer Pilates uses springs that can increase resistance or assist a movement, depending on the exercise and setup. Mat Pilates uses body weight and leverage, and some advanced movements are extremely challenging. Difficulty depends on the specific exercise, technique and resistance rather than whether you’re using a machine.

Does 30 Minutes of Pilates Count as a Workout?

Yes. Thirty minutes of Pilates counts as physical activity and may provide meaningful strength, endurance or flexibility work. Whether it’s sufficient for your goals depends on the exercises and their difficulty. A short class may be useful, but it doesn’t automatically replace the resistance or aerobic training your program needs.

Is Pilates Three Times a Week Enough for General Fitness?

Three weekly Pilates sessions can improve several aspects of fitness, especially for beginners. Whether they provide enough overall exercise depends on intensity and the muscles trained. You may still need aerobic activity and additional resistance work to meet public-health recommendations or achieve more specific strength and muscle-building goals.

Maik Wiedenbach’s Verdict: Should You Choose Pilates or Weightlifting?

Pilates can improve strength, flexibility and movement control. That makes it a legitimate training option.

But when the goal is substantial muscle growth or maximal strength, progressive resistance training remains the more direct, better-supported foundation and has been for the past 70 years..

You don’t have to choose a side in the Pilates-versus-weights argument.

Choose a program that produces the adaptations you’re after.
