The six-week check is a floor, not a green light

The standard postnatal check confirms healing is progressing; it is not an assessment of readiness for loaded exercise. Many people leave it believing they are cleared for anything, which is how early setbacks happen.

A more useful gate is functional: can you breathe, brace and move without leaking, doming or pain? That is the readiness test, and it varies enormously between individuals.

Diastasis recti in practice

Some separation of the abdominal midline is universal at the end of pregnancy and resolves substantially on its own in most people over the first few months. What matters is not the gap width alone but whether you can generate tension across it.

The practical test is doming: if a ridge appears along the midline during an abdominal effort, the load is beyond what the connective tissue currently manages. Reduce the demand rather than pushing on.

  • Weeks 0–6: breathing, gentle pelvic floor, walking
  • Weeks 6–12: stability work, side-lying, supported reformer work
  • Weeks 12+: progressive loading if no doming and no leaking
  • Any leaking or doming means step back a stage
  • Caesarean recovery adds roughly four to six weeks before loaded work

Why the reformer helps here

Supported positions allow meaningful work before you can hold yourself against gravity, and spring assistance lets you train the pattern at a load your tissue tolerates.

The side-lying and seated repertoire is particularly useful in the early months, when supine work may be uncomfortable and prone work is off the table.

What not to rush

Loaded spinal flexion — sit-ups, teaser, short spine — and high-impact work are the two things worth deferring longest. Both load exactly the structures that are still recovering.

Returning to running before pelvic floor and hip strength has been rebuilt is the most common cause of persistent postnatal problems, and it is entirely avoidable with a few months of preparatory work.
