Pilates is often debated in fitness circles: Is it just flexibility and posture work, or does it qualify as real strength training? The short answer is that pilates can build strength, but it isn’t identical to traditional strength training like weightlifting or resistance workouts. It shines in areas that many conventional strength programs overlook.
Understanding how Pilates fits into the strength training spectrum helps you use it effectively, whether you want muscle tone, functional movement, injury prevention, or a foundation for heavier lifts.
What is Pilates?
Developed by Joseph Pilates in the early 20th century, Pilates is a low-impact exercise method focused on core stability, postural alignment, and muscle balance. It isn’t just “stretching.” Every movement is built on six core principles: breath, concentration, control, centering, flow, and precision.
Pilates can be done on a mat using bodyweight or on specialized equipment like the Reformer, which introduces adjustable resistance through springs.
What Strength Training Actually Means
To understand if Pilates is strength training, we first must define resistance exercise. Resistance exercise involves working against a force to make muscles contract. This includes bodyweight movements (like push-ups), resistance bands, machines, or free weights. The purpose is to overload the muscles so they adapt and get stronger. Resistance exercise is the core principle behind traditional strength training.
Pilates uses resistance too through bodyweight control, springs on machines, or external tools like bands, making it a form of resistance exercise, though typically lighter than what you’d see in a gym.
What Should I Choose For Strength, Mat or Reformer Pilates?
The type of Pilates you choose impacts how much strength you build.
Mat Pilates:
- Using your own bodyweight.
- Developing core strength, muscular endurance, and neuromuscular control.
- Lowers external resistance, focus on precision and posture.
Reformer Pilates:
- Using a machine with adjustable spring resistance.
- Offers a wider range of load and progressive challenges.
- Can significantly increase full-body muscle engagement and tone, making it closer to traditional resistance training than mat work alone.
Reformer can be especially effective if your goal is noticeable strength improvements while retaining Pilates’ signature focus on movement quality.
Pilates Resistance Exercises to Help Build Strength
Pilates builds strength in a very specific way: through continuous muscle engagement, controlled resistance, and precise movement patterns. Instead of relying on heavy external loads, Pilates challenges the body by increasing time under tension, improving muscle coordination, and activating deep stabilizing muscles that are often underused in traditional workouts.
One of the key strength benefits of Pilates resistance exercises is that muscles rarely “switch off.” Movements are slow and deliberate, which forces the body to maintain control throughout the entire range of motion. This constant engagement trains muscles to work efficiently together, improving functional strength rather than isolated muscle power.
Lower-body Strength
Lower-body strength is developed through exercises such as Pilates squats, lunges, bridges, and Reformer leg presses. These movements heavily activate the glutes, hamstrings, quadriceps, and inner thighs while also requiring core stability. On the Reformer, adjustable spring resistance allows these exercises to be progressively overloaded, making them more challenging as strength improves.
Core Strength
Core strength is at the heart of Pilates resistance training. Exercises like roll-ups, roll-downs, planks, and teaser variations strengthen the deep abdominal muscles, including the transverse abdominis and obliques. Unlike traditional crunches, pilates core work emphasizes spinal support, control, and breathing, which translates into better posture and reduces injury risk.
Upper-body Strength
Upper-body strength is developed through controlled pushing and pulling movements such as arm presses, rows, chest expansion, and plank-based variations. On the Reformer, arm straps and springs create resistance that strengthens the shoulders, chest, arms, and upper back while maintaining joint safety and proper alignment. This is especially beneficial for building shoulder stability and improving posture.
Pilates Resistance Exercises For Frozen Shoulder
In addition to proper exercise, pilates resistance exercises can be very helpful for frozen shoulder, when they’re done gently, progressively, and at the right stage of recovery.
Frozen shoulder (adhesive capsulitis) needs controlled movement, not force. Pilates especially, Reformer Pilates, checks the right boxes:
- Low-load, controlled resistance
Springs provide smooth, adjustable resistance that supports the arm instead of forcing it. - Pain-free range focus
Movements stay within a safe range, which is crucial for recovery. - Joint-centered strength
Strengthening the muscles around the shoulder (rotator cuff, scapular stabilizers) helps restore movement without aggravation. - Improved circulation & tissue hydration
Gentle movement helps reduce stiffness over time.
Conclusion
So, does Pilates count as strength training? Yes, especially when practiced on the Reformer with purposeful resistance, control, and progression. While Pilates may not replace heavy weightlifting for maximal muscle size, it excels at building functional strength, core stability, joint support, and balanced muscle activation that carries over into everyday movement and long-term body health.

FAQ
Is Reformer Pilates strength training?
Yes, Reformer Pilates qualifies as a form of strength training because it uses resistance to challenge muscles. The adjustable springs provide variable load, making it more comparable to resistance exercise than mat Pilates alone.
Can Pilates replace weight lifting?
Pilates can certainly improve strength, control, posture, and muscular endurance, but it usually won’t match traditional weight lifting for raw hypertrophy or maximal strength because it doesn’t typically use heavy progressive loads. Pilates is best used as a complement to weight training or as a stand-alone program for functional strength and movement quality.
How Often Should I Do Pilates?
Aim for 2-4 sessions per week to see improvements in strength and mobility. Beginners can start with 1–2 classes and gradually increase frequency. Consistency, not intensity alone is what builds lasting strength and body control.
