Diastasis recti and exercise: build function, not a fear of your core

What the review can—and cannot—tell you

The postpartum systematic review in the British Journal of Sports Medicine found that abdominal training can reduce inter-rectus distance, with limitations in the evidence. Programs and measurement methods varied. A narrower gap should not be assumed to guarantee less pain, better function, or a particular appearance. The review does not identify one universally best core routine.[1]

Ask about function as well as distance

A physiotherapist can assess your abdominal wall and discuss symptoms, the way you manage a task, pelvic floor concerns, and your return goals. Tell them whether the difficulty is lifting a child, getting out of bed, returning to a gym exercise, or something else.

• Which movement is uncomfortable or feels difficult to control?
• Are you also noticing pelvic pain, leakage, or heaviness?
• How will we measure meaningful progress beyond a gap?
• Which signs mean the current exercise needs a different dose or variation?

An internet finger-width test cannot answer all of these questions. Measurements may be useful, but they should be interpreted in the context of your assessment rather than used as a daily score.

Make a movement easier to practise

An individual exercise can be adjusted by changing the range, body position, support, resistance, or number of repetitions. For example, an exercise that feels too demanding on the floor may become more manageable when supported or performed through a smaller range. This is a coaching strategy to explore with your clinician, not a prescription to treat a separation.

Take an ordinary task you want to improve and build toward it. Notice comfort, confidence, and your response afterward. A plan that connects practice to daily life is easier to evaluate than a long list of exercises you are afraid to attempt.

Reconnect core work with the rest of training

Once you have appropriate guidance, a return plan can include daily movement and gradual whole-body exercise rather than endless isolated “repair” work. The Canadian postpartum guideline frames activity around capacity, contraindications, and recovery. It does not require an identical timeline for everyone.[2]

Choose one or two observations you can use: getting up more comfortably, tolerating a manageable carry, or repeating a familiar movement with less uncertainty. Bring setbacks to your practitioner so the plan can change with you.
