Question

how can muscles be big but not strong, like body builders vs rock climbers?

In: Biology

Answer 1

One aspect of strength is neurological. It’s like, how much voltage you can apply to the circuits that squeeze your muscles.

Even small people can have strong muscles if they train for it.

But strength generally also scales with muscle size.

Handwaving here a bit, but strongmen have both kinds of strength, bodybuilders primarily just the strength from muscle size, and climbers primarily just the neurological strength.
