The Claim

A 4-week supervised Pilates program performed five times per week for 50 minutes per session significantly reduces inter-recti distance at all three measured sites (above, at, and below the navel) and improves abdominal muscle endurance in primiparous women 2–12 months postpartum, compared to no intervention.

Cause and effect

In plain English

In women who have recently given birth, a structured Pilates program performed five times a week for 50 minutes over four weeks can reduce the separation between the abdominal muscles and increase core endurance compared to not doing any exercise.

A 4-week supervised Pilates program performed five times per week for 50 minutes per session significantly reduces inter-recti distance at all three measured sites (above, at, and below the navel) and improves abdominal muscle endurance in primiparous women 2–12 months postpartum, compared to no intervention, suggesting targeted core exercise can improve abdominal wall integrity and function during early postpartum recovery.

  1. Study: Effects of Pilates on inter-recti distance, thickness of rectus abdominis, waist circumference and abdominal muscle endurance in primiparous women

    This study found that doing Pilates for 50 minutes a day, five days a week, for four weeks helped new moms tighten their stomach muscles and reduce the gap between them, which is something many struggle with after having a baby. No changes happened in moms who didn’t do Pilates.
