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.

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.

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.

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.

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.

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.
