The Claim
Supervised, low-to-moderate intensity strength training performed twice weekly for 12 weeks in pregnant women with a history of back pain is associated with a 56% increase in leg extension load, a 41% increase in lumbar extension load, and a 14% improvement in lumbar endurance, without causing musculoskeletal injuries or adverse changes in blood pressure.
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.
For pregnant women who've had back pain before, doing gentle strength exercises twice a week for 12 weeks might make their legs and lower back stronger and more enduring, without hurting them or raising their blood pressure.
