Beginners get the biggest strength boosts from lifting weights, but even they get way stronger at moving weights than at holding still — the gap between those two types of strength stays the same no matter how fit you are.

Beginners get way stronger from weight training than experienced lifters, and even among beginners, they get much stronger at moving weights than at holding them still.

Even though lifting weights makes your muscles bigger and more active, those changes don’t explain why you get stronger at dynamic movements but not at holding static positions — something else, like how your brain coordinates movement, might be more important.

Even though lifting weights makes your muscles bigger and more active, those changes don’t explain why you get stronger—meaning something else, like how your nerves coordinate movement, might be more important.

Getting stronger at lifting weights doesn’t make you much stronger at pushing or holding something still — they’re like two different kinds of strength, not just one ability measured two ways.

Being strong at lifting weights doesn’t mean you’re strong at pushing or holding something still—even with the same muscles—because your body uses different systems for moving vs. holding.
