The Claim
A 4-week Pilates program in primiparous women 2–12 months postpartum has no significant effect on rectus abdominis muscle thickness, indicating that improvements in abdominal function and inter-recti distance may occur without muscle hypertrophy and may be driven by neuromuscular activation or connective tissue adaptation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After having a baby, doing Pilates for four weeks does not make the main abdominal muscle thicker, but it may still improve core function by changing how nerves activate the muscles or by strengthening the connective tissues between them.
See the scientific wording
In primiparous women 2–12 months postpartum, a 4-week Pilates program does not significantly alter rectus abdominis muscle thickness, suggesting that changes in abdominal function and inter-recti distance may occur independently of muscle hypertrophy, and may be mediated by improved neuromuscular activation or connective tissue adaptation.
What the research says
1 studyThis study found that doing Pilates after having a baby helped tighten the gap between stomach muscles and made core strength better—even though the stomach muscles themselves didn’t get thicker. So, the body got stronger without the muscles growing bigger.
