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.

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

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.

Lifting weights with movement (like squats or bench presses) makes you much stronger at those exact movements, but doesn’t make you much stronger at holding a static position—even if you’re using the same muscles.

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.
