This study looked at many other studies to see if lifting heavy or lighter weights builds muscle better.
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.

Lifting very heavy weights a few times with long breaks builds more muscle and strength faster than lifting lighter weights many times with short breaks, when the total amount of lifting isn't the same.
Lifting heavy weights and lifting lighter weights can both build muscle just as well for different people, as long as you do the same total amount of work. It suggests that how hard you push might not be the main thing that matters for muscle growth.
Lighter weight lifting with more reps might be safer and easier to stick with than pushing yourself to the max every time.
Lifting heavy weights puts stress on your muscles, which is thought to be a main reason they get bigger and stronger.
