See the scientific wording

A 4-week supervised Pilates program performed five times per week for 50 minutes per session significantly reduces waist circumference by approximately 2.85 cm in primiparous women 2–12 months postpartum, compared to no intervention, indicating that core-focused exercise can contribute to reductions in abdominal girth during early postpartum recovery.

What the research says

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

    Women who did Pilates for 50 minutes a day, five days a week, for four weeks after having a baby lost about 3 cm around their waist—while those who didn’t do anything didn’t. So yes, Pilates helps shrink the belly after childbirth.
