how can muscles be big but not strong, like body builders vs rock climbers?
In: Biology
This phenomena is related to the [square-cube law](https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://en.m.wikipedia.org/wiki/Square%25E2%2580%2593cube_law%23:~:text%3DThe%2520square%25E2%2580%2593cube%2520law%2520can,the%2520cube%2520of%2520the%2520multiplier.&ved=2ahUKEwiOlo3wpK-EAxVvnGoFHVr1B4kQFnoECBEQBQ&usg=AOvVaw2mk90KFru6H523NHVGGd0k) which talks about how as the surface area of something squares, its volume increases by its cube. It’s a scaling issue and is the same reason babies and even kids can display such incredible displays of strength like dead hanging from their hands for such long periods of time because their strength in relation to their size is better. Or put another way, their strength to weight ratio is far more beneficial
Body builders are incredibly strong, they can move figurative mountains and are among the strongest people on the planet. But their muscle volume is so much larger and thus so much heavier that doing body weight type work is more difficult.
