The pelvic floor is a group of muscles and connective tissues spanning the bottom of the pelvis, acting like a hammock. These muscles support the bladder, bowel, and uterus, maintain continence, and provide core stability. The concern that squatting is inherently damaging is largely a misunderstanding of its natural function. Squatting is a fundamental human movement, and when performed correctly, it is safe and beneficial for improving pelvic floor resilience and coordination.
Understanding the Pelvic Floor During a Squat
The pelvic floor is designed to move dynamically in response to changes in intra-abdominal pressure (IAP) and body position. During the eccentric (downward) phase of a squat, the pelvic floor muscles naturally lengthen and descend. This controlled lengthening promotes flexibility and blood flow, which is necessary for muscle health.
The concentric phase (upward push) requires the muscles to shorten and lift reflexively. This action works the pelvic floor against resistance, strengthening the muscle and building its capacity to manage pressure.
Undue strain is caused by failure to coordinate this movement, such as bearing down or holding breath, not the squat itself. The pelvic floor is part of the “inner core” canister, working in synergy with the diaphragm, deep abdominal, and back muscles. When these systems are in sync, they manage IAP effectively, preventing excessive downward force onto the pelvic organs.
Safe Squatting Technique for Pelvic Floor Engagement
Effective pressure management during a squat relies heavily on proper breathing technique, which directly influences IAP. The general recommendation is to inhale on the way down, allowing the diaphragm to descend and the pelvic floor to lengthen. Exhaling on the way up, particularly through pursed lips, helps engage the deep core muscles and causes the pelvic floor to lift and contract.
Holding one’s breath, known as the Valsalva maneuver, dramatically increases IAP to stabilize the spine during maximal lifts. However, for general fitness or high-repetition work, this breath-holding directs excessive force downward onto the pelvic floor, potentially worsening symptoms like incontinence. Exhaling on exertion allows the pressure to escape upward and outward, protecting the pelvic floor from overwhelming downward strain.
Squat depth and foot positioning also affect pelvic floor stretch and angle. A wider stance or a deeper squat increases the lengthening of the pelvic floor muscles. While a deep stretch can be beneficial for a healthy pelvic floor, forcing depth beyond hip mobility can cause the pelvis to tuck under (a “butt wink”). To protect the spine and the pelvic floor, only squat to a depth where a neutral spinal curve can be maintained.
When Specialized Modification is Required
Squatting must be significantly modified or temporarily avoided if pelvic floor dysfunctions are present. Individuals experiencing symptoms like heaviness, bulging, or increased urine leakage during the exercise should immediately adjust their routine. These symptoms indicate the pelvic floor’s pressure-management system is overloaded.
Modifications for Dysfunction
For those with pelvic organ prolapse (POP) or severe stress incontinence, modifications include decreasing the range of motion and reducing external weight. Using a box to limit depth and focusing on a narrower stance helps reduce downward pressure. Bodyweight squats or supported movements, like squatting to a chair, are often the starting point for rehabilitation.
Postpartum Caution
The immediate postpartum period requires special caution, with women needing six to twelve weeks before incorporating squats back into their routine. Returning to exercise too soon can delay healing and aggravate conditions like diastasis recti or pelvic floor weakness. A Pelvic Floor Physical Therapist (PFPT) provides a personalized assessment and phased return-to-exercise program.
