Women who lifted light weights or heavy weights, both until they couldn't do another rep, got just as strong over 12 weeks.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

When lifting lighter weights, pushing until you can't lift anymore helps build bigger muscles, but this doesn't happen with heavier weights. Heavier weights always build more strength than lighter ones, no matter how hard you push.
Lifting light or heavy weights to exhaustion for 12 weeks didn’t change body fat or muscle mass in women who had never lifted before.
Women who had never lifted weights before got stronger in their arms and legs after doing 12 weeks of lifting light or heavy weights to exhaustion — and both ways made them just as strong.
If you’ve never lifted weights before, you can get stronger by doing either light or heavy weights — as long as you push each set until you can’t do another rep.
Maximal strength gains (1RM) are greater when training with higher relative loads (>80% 1RM) compared to training with lower loads, even when total volume and proximity to failure are matched.
