Is pilates strength training? The short answer is no. Pilates builds core stability and flexibility, but it does not build muscle mass or increase bone density the way lifting weights does. If your goal is to get stronger and protect your body as you age, you need actual resistance training with progressive overload.
What does pilates actually do for your body
Pilates works your core muscles and improves your balance and flexibility. You hold positions and move through controlled motions that challenge your stabilizer muscles. This makes it good for posture and body awareness.
But here is the problem. Pilates does not provide enough resistance to trigger real muscle growth. Your muscles need to lift heavy loads to break down and rebuild bigger and stronger. A reformer spring or your own bodyweight simply cannot match what a barbell or dumbbells can do.
Fitness expert Senada Greca trains celebrities like Kim Kardashian. She puts it simply. Pilates and yoga are great additions to strength training for endurance and flexibility, but they will not build muscle or bone density like lifting weights. The best approach combines both.

Why does this matter for your health
Bone density peaks when you reach 25 to 30 years old and then starts declining. By age 40 the loss speeds up. Muscle mass drops by 3 to 8 percent every decade after you turn 30.
This creates real danger as you age. Falls kill over 32,000 people every year and that number has nearly doubled in the last decade. When you fall with weak bones and little muscle, you break things. Strong muscles and dense bones protect you from serious injury.
Strength training is the only exercise that builds both muscle and bone at the same time. Pilates cannot do this because it lacks the heavy loading your bones need to adapt and grow denser.
How strength training builds muscle and bone
For muscles to grow you must challenge them with more weight than they can handle easily. This causes tiny tears in the muscle fibers. Your body repairs these tears and builds the muscle back bigger and stronger.
Scientists call this progressive overload. You add more weight or more reps over time and your body keeps adapting. A 2017 meta analysis found you can build muscle with anywhere from 5 to 30 reps per set as long as you push close to failure.
Bones work the same way. Heavy loads stress the bone and signal it to lay down more mineral. This is why weight training increases bone density while activities like pilates and walking do not.
Can pilates help you lose weight
Exercise alone is not very effective for weight loss. When researchers had people burn 2000 calories per week through cardio, the average fat loss was less than half what they expected. Some people lost nothing at all.
Your body compensates. You move less during the rest of the day and you get hungrier. A calorie deficit through diet works much better than trying to exercise the weight off.
Pilates burns fewer calories than strength training anyway. Building muscle raises your metabolism because muscle tissue burns about 6 calories per pound per day at rest. Fat only burns 2 calories per pound. Over years of muscle gain this adds up.
What about mat pilates versus reformer pilates
Reformer machines add spring resistance which makes the exercises harder. But even reformer pilates cannot match the loads you can lift with free weights or machines at a gym.
A typical reformer might provide 20 to 50 pounds of resistance depending on the springs. Compare that to a beginner doing goblet squats with a 15 kilogram dumbbell or a deadlift with 40 kilograms. Within months most people can lift far more than any reformer provides.
Mat pilates uses only your bodyweight. This limits how much you can progress. You need to keep adding challenge for muscles to keep growing and bodyweight alone runs out of options quickly.
Who should do pilates
Pilates works well for certain goals
- Recovering from injury when you need gentle movement
- Improving flexibility and mobility
- Learning body awareness and control
- Adding variety to your training week
- Reducing stress through mindful movement
It does not work well if you want to
- Build significant muscle mass
- Increase bone density
- Get stronger for sports or daily activities
- Protect yourself from falls and fractures as you age
How to combine pilates with strength training
The best approach uses strength training as your foundation and pilates as a supplement. Train with weights 2 to 4 times per week focusing on big movements like squats and deadlifts and rows and presses. Add pilates once or twice weekly for mobility work.
Research shows you need at least 10 sets per muscle group per week to maximize growth. Nearly double the gains compared to just 5 sets weekly. Pilates does not count toward these sets because the resistance is too low to stimulate real adaptation.
For your strength sessions aim for 45 to 60 minutes of actual work after warming up. Going longer than 60 minutes raises cortisol levels which can hurt your recovery.
What exercises build the most strength
Focus on compound movements that work multiple joints and large muscle groups
- Squats for legs and core
- Deadlifts for back and hamstrings and glutes
- Bench press or pushups for chest and shoulders and triceps
- Rows for back and biceps
- Overhead press for shoulders and triceps
These movements load your skeleton and muscles far more than any pilates exercise. A basic squat with your bodyweight already provides more stimulus than most pilates moves and you can keep adding weight forever.
How much protein do you need
Building muscle requires adequate protein. Aim for 0.8 grams per pound of bodyweight daily. A 70 kilogram person needs about 125 grams of protein spread across their meals.
Protein also helps with fat loss. Your body burns 20 to 30 percent of protein calories just digesting it compared to only 5 to 10 percent for carbs and 0 to 3 percent for fat. Studies show switching to a high protein diet raises your daily calorie burn by 4 to 5 percent.
FAQ
Is reformer pilates considered strength training
No. Reformer pilates provides some resistance but not enough to build muscle or bone density. The springs max out at relatively light loads that your body adapts to quickly. You need progressive overload with heavier weights to trigger real strength gains.
Can pilates replace the gym
It cannot replace weight training for building muscle and bone. Pilates works as a complement to strength training but not a substitute. If you only have time for one type of exercise, choose weight training for the health benefits.
Will pilates tone my body
The word toning means losing fat and building muscle so you can see muscle definition. Pilates does not build much muscle. For visible muscle tone you need strength training to build the muscle and a calorie deficit to lose the fat covering it.
How many times per week should I do pilates
One to two sessions weekly provides the flexibility and core benefits without cutting into your recovery from strength training. More than that starts taking time and energy away from the training that actually builds muscle and bone.
Is pilates good for older adults
Pilates can help older adults with balance and mobility. But strength training matters more as you age because it fights the muscle and bone loss that leads to falls and fractures. Start with bodyweight exercises or light weights and progress gradually.
Does pilates build core strength
Pilates builds core endurance and stability but not maximal core strength. For actual core strength you need exercises with resistance like weighted planks and cable rotations and loaded carries. The core muscles respond to progressive overload just like any other muscle.
Understanding how Pilates fits into your routine can help you achieve better results—combine it with skincare strategies like exploring whether castor oil helps reduce cellulite. For older adults, pairing Pilates with proper nutrition is key, so discover what to eat to gain muscle after 60. Many Pilates enthusiasts also benefit from overnight fasting protocols to support lean muscle development.
