Plus, the nine best moves to add to your routine.
Pilates—the low-impact, core-centric exercise method—is having a moment. Yes, the slow, controlled movements are challenging and can fire up your abs in just minutes (just try the Pilates hundred!)
But even if Pilates is your go-to workout, don’t ditch your weightlifting or cardio routine just yet. While a regular Pilates practice can help improve overall body strength and muscle, there’s a limit to those gains, says Christine Sellers, NCPT, certified Pilates instructor at Bridge Body Clinic and Training Center in Atlanta.
Even if your usual Pilates class leaves you a sweaty, shaky mess, your heart rate won’t get elevated long enough to have cardiovascular benefits, either.
That sweating and shaking isn’t for nothing, though. Pilates can increase balance, mobility, and total-body strength. But does it count as strength training? The answer: Yes and no.
While you can build strength and muscle doing Pilates—and it’s a great supplemental form of exercise—our experts say it shouldn’t take the place of a consistent weight-training routine. Here’s all you need to know about when to use Pilates as strength training—and when to mix it up.
“You can absolutely build both muscle and strength with Pilates,” says Abby Suskin, CPT, a certified personal trainer, certified BASI Pilates instructor, and founder of Pilates With Abs. “Pilates is a form of resistance training, meaning it’s a type of exercise that works against an external force to build muscular strength and endurance.”
With traditional strength training, that force comes from a free weight or barbell. In Pilates, your body weight, a reformer spring, or a resistance band can provide that same resistance.
“A well-programmed Pilates class will load all major muscle groups and build strength through low-impact, slow, sustained movements,” Suskin says.
The bottom line? With a regular, balanced Pilates regimen, you’ll increase overall body strength—especially if you’re working out on equipment like a reformer.
Because Pilates is a bodyweight activity, “you can get stronger and build muscle with the mat repertoire, depending on the strength level you came in with,” Sellers says.
Traditional Pilates exercises like shoulder bridges and push-ups can also challenge load and build strength—at first, according to Sellers. But once you reach a certain fitness level, it’s challenging to build more strength and muscle with those bodyweight-only movements, That’s because your muscles get strengthened by increased load, and the benefits of Pilates will level off over time.
Both Sellers and Suskin recommend adding light weights, loop bands, and other props to mat Pilates exercises to increase resistance and build more muscle load once you’ve aced the basics.
Pilates is best for building muscle and strength in your core, the deep abdominal muscles that support your spine, according to Suskin.
“A Pilates class will focus on exercises that build core strength and endurance, and your teacher will cue you to breathe at certain points during an exercise to maximize the activation of your core muscles,” she says.
Traditional Pilates exercises like the single-leg stretch and roll-up target and strengthen deep abdominal muscles like the transverse abdominis and obliques, which improve overall posture and mobility, helping to prevent injuries and lower back pain.
While you may work up a sweat during a great Pilates workout, unfortunately it doesn’t count as cardio, Sellers says.
“Cardio is any form of movement that gets your heart rate up and keeps it there for an extended period of time,” she explains. “There are points during a mat workout when your heart rate will elevate, but typically, it isn’t for long enough to truly reap the benefits.”
For maximum heart and metabolic benefit, you’re better off doing continuous aerobic activity like running or biking, Suskin says.
Yes, you’ll gain some strength benefits from doing Pilates, but lifting weights is the best way to build muscle, according to Suskin.
“Strength is just one component of a Pilates workout, whereas the goal of weightlifting is to increase muscle size [hypertrophy] through progressively adding more load and stress to muscles over time,” Suskin says. “If your goal is to increase strength using bodyweight and lighter loads, Pilates will absolutely help you get stronger,” she continues. But if you want to increase muscle size, she recommends a traditional strength-training program.
Weightlifting is especially important as you age, because lifting heavy will not only improve your strength, but your mobility, which can help prevent injuries, Sellers says.
With its emphasis on core strength and flexibility, “Pilates can be a great way to supplement that strength training and also help prevent injury,” Suskin adds.

This Pilates staple challenges your balance while strengthening your glutes, quads, core, and arms, Sellers says.
Up the intensity by lifting both arms overhead while extending one leg out in front of you.
Add a challenge to this core staple with light weights.
If you feel strain in your neck, ditch the weights or lower your head back to the mat.
This arm and core burner works your internal and external obliques as well as your biceps and triceps.
A combination of a clamshell and a plank, this full-body move works your glutes, hips, arms, and obliques.
To lower the intensity, remove the weight and/or keep your lower hip on the ground.
This bodyweight exercise builds upper-body strength by working muscles like your chest, arms, and back.
Try one of these push-up alternatives that work the exact same muscles.
This exercise fires up your obliques, arms, and hips while also improving balance.
Modify the exercise by keeping the knees bent and down on the mat.
This prone (on your back) exercise works your posterior chain, or the muscles on the back side of your body.
If you feel any tension in your lower back, keep your legs on the mat and lift only your upper body.
In a traditional Pilates movement, the roll-up helps to mobilize your spine and build core strength.
Bend your knees or use your hands behind your thighs for support as you roll up and down.
A staple of Pilates and strength training classes, the bridge works your core, hamstrings, and glutes while improving balance.
Add a weight or bar on top of your hips to add more load and make the exercise harder.
Pilates is known for its slow, controlled movements, which are ideal for building core strength and improving mobility and balance. Those bodyweight moves can also help you strengthen your arms, back, glutes, hips, and hamstrings—up to a point.
Muscle-building requires increased load. For the best results, incorporate weights or other resistance-type props into Pilates exercises, like the ones listed above, and commit to a traditional strength-training program at least two times per week.
