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.

Even though your muscles get bigger and fire more during weight training, those changes don’t explain why you get stronger at dynamic movements but not static holds—something else, like how your brain coordinates the movement, is more important.

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.

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.
