The Claim
In pregnant women with a history of back pain, supervised strength training over 12 weeks leads to a progressive increase in external load across all major exercises, with the greatest gains observed in leg extension (56%) and lumbar extension (41%), while perceived exertion remains stable at low-to-moderate levels (RPE 10.5–12.9).
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.
Pregnant women who've had back pain before can safely do supervised strength training for 12 weeks and get stronger—especially in their legs and lower back—without feeling like they're working any harder than before.

What the research says
1 studyStudy: Safety and efficacy of supervised strength training adopted in pregnancy.
This study found that pregnant women with back pain who did supervised strength training twice a week for 12 weeks got stronger, especially in leg and lower back exercises, without feeling overly tired or getting hurt. This matches exactly what the claim says.
