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 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 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 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.

Getting stronger from lifting weights doesn’t always mean your muscles are getting bigger—and vice versa. Strength and size don’t go hand in hand.
