Pilates does strengthen the pelvic floor, and clinical trials show it can be as effective as traditional pelvic floor exercises (Kegels) for improving muscle endurance and reducing urinary leakage. The key is that many Pilates movements activate the pelvic floor indirectly through core engagement and breathing patterns, even when you’re not consciously squeezing those muscles. That said, the relationship between Pilates and pelvic health isn’t entirely straightforward. Some intense exercises can actually make certain pelvic floor problems worse.
How Pilates Activates the Pelvic Floor
Your pelvic floor muscles are part of a team of deep stabilizers that includes the diaphragm, the deepest abdominal layer (the transversus abdominis), and small muscles along the spine. These muscles don’t work in isolation. When you engage your deep core during a Pilates exercise, you’re creating a pressure change inside your abdomen that triggers your pelvic floor to contract as well.
Research measuring electrical activity in the pelvic floor during Pilates found that the greatest activation occurred during core-intensive positions like the teaser and plank. Positions that work against gravity, such as standing or upright exercises, produced stronger involuntary pelvic floor contractions because the muscles had to work harder to counteract downward pressure. Over time, this repeated activation appears to improve proprioception, meaning you develop a better ability to sense and control those muscles without thinking about it.
The breathing technique used in Pilates also plays a role. During exhalation, the deep abdominal muscles naturally co-contract with the pelvic floor. Pilates emphasizes controlled exhales during the effort phase of each exercise, which reinforces this coordination pattern every repetition. This is why Pilates instructors often cue you to “exhale on the effort.” It’s not just about oxygen. It’s a strategy for engaging your entire deep core system, pelvic floor included.
How It Compares to Kegel Exercises
A randomized controlled trial comparing Pilates to traditional pelvic floor muscle training in 40 postmenopausal women with stress urinary incontinence found that both approaches significantly reduced daily urine leakage and improved quality-of-life scores. Both groups improved in muscle endurance. Peak muscle strength on pressure measurements actually improved only in the Pilates group, while overall muscle grading improved only in the Kegel group. The researchers concluded there was no meaningful difference between the two approaches, as long as the Pilates exercises included voluntary pelvic floor contractions.
That last detail matters. Pilates alone, without any conscious pelvic floor engagement, likely produces weaker results than Pilates combined with intentional squeezing during exercises. If your instructor cues you to “lift your pelvic floor” during movements, that integration is what closes the gap between Pilates and dedicated Kegel training.
Modified Pilates added to standard physiotherapy care appears to be even more beneficial than either approach alone. It also offers practical advantages: no internal devices, a more enjoyable exercise experience for people who dislike repetitive Kegels, and lower overall treatment costs.
Postpartum Pelvic Floor Recovery
After childbirth, the timeline for reintroducing core and pelvic floor work is more conservative than many people expect. Current rehabilitation guidelines suggest that gentle pelvic floor contractions and relaxation can begin in the first two weeks postpartum, but only if they don’t cause symptoms. During weeks three and four, the focus shifts to coordinating pelvic floor activation with deep abdominal engagement and diaphragmatic breathing, using positions like lying on your back, side-lying, and hands-and-knees.
Full Pilates-style exercises typically come later, and progression should ideally be guided by a pelvic health physical therapist who can confirm your pelvic floor muscles are both contracting and relaxing correctly. The traditional six-week medical clearance is a starting point, not a finish line. Conditions like urinary incontinence, abdominal separation, and pelvic organ prolapse are common postpartum and can limit what’s safe to do. Movements that cause visible “coning” along the midline of your abdomen suggest the tissue isn’t ready for that level of load and should be modified or removed until you can perform them without that bulging pattern.
When Pilates Can Make Things Worse
Not all pelvic floor problems come from weakness. Some people have a hypertonic, or overactive, pelvic floor where the muscles are too tense and struggle to relax. For these individuals, intense Pilates core exercises can worsen symptoms by layering more activation onto muscles that are already locked in a contracted state. Sustained core holds without adequate relaxation phases are the main culprit.
Several common Pilates exercises carry higher risk for pelvic floor overload:
- The Hundred: Prolonged abdominal engagement with legs raised creates significant downward pressure and sustained pelvic floor tension.
- Scissors: Similar mechanics with potential for both overload and insufficient relaxation between contractions.
- Dead Bugs: Activates the same deep muscles without built-in relaxation phases.
- Roll Ups: The rolling motion generates intense intra-abdominal pressure that can strain a vulnerable pelvic floor.
Women with existing pelvic organ prolapse, those recovering from prolapse surgery, and anyone with known pelvic floor muscle spasm should modify or avoid these exercises. A pelvic health physiotherapist or a knowledgeable Pilates instructor can substitute lower-intensity variations that build strength without pushing already-tight muscles further into dysfunction.
Getting the Most Pelvic Floor Benefit
If strengthening your pelvic floor is a primary goal, a few adjustments to your Pilates practice make a significant difference. First, consciously engage your pelvic floor during exercises rather than relying solely on indirect activation. Think of gently lifting the muscles you’d use to stop the flow of urine, then coordinate that lift with your exhale as you perform each movement.
Second, prioritize exercises in gravity-challenging positions. Standing Pilates work and planks generate stronger involuntary pelvic floor contractions than supine exercises. As your strength improves, progressing from lying down to upright positions naturally increases the demand on your pelvic floor.
Third, pay attention to relaxation. A healthy pelvic floor both contracts and releases fully. If your practice is all squeezing and no letting go, you risk developing tension that mimics weakness (difficulty controlling leakage, pelvic pain, or urgency) even though the muscles are technically strong. Include breath cycles between exercises where you consciously soften and release your pelvic floor completely.
Consistency matters more than intensity. The clinical improvements seen in trials came from regular practice over several weeks, not from occasional high-effort sessions. Two to three Pilates sessions per week with mindful pelvic floor engagement is a realistic and effective starting point for most people.
