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.
Working out while pregnant doesn't make it more likely for a mom to lose the baby, have the baby too early, or have a baby with low weight — it's generally safe for most pregnant women.
