Muscles to consider in diastasis rehab

Diastasis is a whole body issue. So much focus can be placed on TVA that the rest of the core cylinder can be forgotten. Our core is not designed to work as individual muscles, but as a "cylinder" of support comprising of the diaphragm, TVA (deep abdominals, pelvic floor and mulitifidus (deep spinal muscles). When we re rehab a diastasis, the whole core has to be involved.
If any non-core muscle is restricting any element of the cylinder, it is also going to have an affect on the deep abdominals. For example, if your obliques are tight and your diaphragm is not moving freely as you breathe, one element of the core cylinder is restricted. When you try and do your core exercises, the lack of diaphragm engagement is going to make the whole core less well engaged, reducing the effectiveness of the core exercise to heal the diastasis.

So if you've tried a load of core exercises/pilates and you haven't seen the results your looking for, consider seeing your local woman's health physio for a thorough assessment.
