The Claim
In young women performing resistance exercise to volitional failure, muscle strength increases by approximately 15-27% in arms and legs after 6 weeks, with no statistically significant difference between low (30% 1RM) and high (80% 1RM) load training, indicating that strength gains are not load-dependent when training to failure.
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.
When young women do strength exercises until they can't do any more, their arm and leg muscles get stronger by about 15-27% after 6 weeks. It doesn't matter if they lift heavy or light weights—both ways work just as well for building strength.

What the research says
1 studyThe study showed that both light and heavy weightlifting to failure made women's arms and legs stronger by similar amounts, just like the claim said.
