Men tend to get stronger faster than women when lifting very heavy weights, possibly due to differences in how their muscles and nerves respond to intense training.

One study with women showed a much bigger muscle growth difference than the others — all of which were only with men — suggesting sex might matter, but we need more studies to know for sure.

Men and women gain muscle at about the same relative rate when they train the same way—women just start with less muscle, so they gain less in absolute numbers.

When lifting weights with your arms, whether you use heavy or light weights, you get about the same improvement in how many reps you can do with both heavy and light weights.

Even though rest-pause training helps you lift heavier, it doesn’t make your muscles bigger than regular training—meaning strength and muscle growth might be controlled by different things.
