The primary outcome was IRD at supra\u2010 and infraumbilical levels. Secondary outcomes were LA distortion and thickness. Transversus abdominis (TrA) activation was assessed simultaneously.

Supraumbilically, the crunch showed the greatest IRD decrease (EMM +\u00a02.48\u00a0mm), but this was not significantly different from ADIM, pelvic floor muscle contraction, or de Gasquet exercise (Tukey\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0\u2265\u00a00.07).
