Separation of the abdominal muscles after pregnancy affects a substantial share of women, yet targeted physical therapy offers a reliable path forward for most.
Diastasis recti abdominis, or DRA, describes the widening of the linea alba connective tissue that runs between the two halves of the rectus abdominis. This separation occurs when the abdominal wall stretches under the pressure of pregnancy. Prevalence sits between roughly 30 and 60 percent in the first year after birth, according to longitudinal data from first-time mothers. The figure peaks near 60 percent at six weeks postpartum and declines toward one-third by the twelve-month mark.
Many women notice the gap during routine movements or when they attempt to return to exercise. The condition itself is not always painful, but it often coincides with reduced core stability, altered posture, and sometimes pelvic floor symptoms such as leakage or heaviness.
How pelvic floor physical therapy addresses the separation
A pelvic floor physical therapist begins with a hands-on assessment of the inter-recti distance, breathing mechanics, posture, and the coordination between the deep abdominal muscles and the pelvic floor. Treatment does not rely on traditional sit-ups. Instead, therapists teach controlled activation of the transverse abdominis and pelvic floor muscles while managing intra-abdominal pressure during daily tasks.
Sessions typically progress through breathing drills, gentle core engagement in multiple positions, and functional movements such as rolling, lifting a child, or carrying groceries. Manual techniques may release tight tissues, and some therapists incorporate biofeedback or gentle electrical stimulation when coordination is the main barrier. The goal is to restore the abdominal wall's ability to transfer load across the midline without bulging or doming.
Studies included in a 2024 scoping review of postpartum rehabilitation found that programs combining deep-core work, pelvic floor training, and respiratory strategies produced measurable reductions in the gap and improvements in function. Results varied with the timing of intervention and individual factors, but conservative care remained the recommended first line before any surgical consideration.

One patient's experience with consistent guidance
A woman we'll call Ms. L had tried online postpartum workouts for four months after her second delivery. Her gap measured three finger-widths at the umbilicus, and she still felt unstable when carrying her toddler. After an evaluation with a pelvic health therapist, she began twice-weekly sessions focused on transverse abdominis activation paired with pelvic floor lifts, followed by progressive loading in standing and quadruped positions. Within eight weeks her measured separation narrowed, and she could complete household tasks without the previous sense of pressure. The change came not from intensity but from precise cuing that prevented compensatory patterns she had developed on her own.
What the base rates tell us about recovery timelines
Spontaneous improvement occurs in a portion of cases during the first eight weeks postpartum, after which progress slows without deliberate intervention. When women begin structured pelvic floor and core coordination work earlier, studies report faster and more consistent gains in both the width of the separation and in functional strength. Not every gap closes completely, yet many women regain the ability to perform daily activities and return to exercise without symptoms. The exception appears in cases of very large separations or coexisting hernias, where surgical consultation may eventually enter the conversation after six months of conservative effort.

What this means for your recovery
The practical step is to locate a physical therapist with specific training in pelvic health or women's health physical therapy rather than relying on general fitness programs. An initial evaluation usually lasts forty-five to sixty minutes and includes palpation, movement analysis, and a discussion of goals. From there the therapist builds a home program that fits around childcare and work. Expect to attend sessions for several weeks to months, with the frequency tapering as independent control improves. Early attention to breathing and pressure management prevents the reinforcement of habits that widen the gap further during routine lifting or straining.
One concrete next step
Search the American Physical Therapy Association's Find a PT directory for a clinician credentialed in pelvic health or obstetrics physical therapy, then call to ask about their experience with postpartum diastasis recti. Book the evaluation even if symptoms feel mild; objective measurement and tailored instruction at the outset shorten the overall timeline for most people.
