Question

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

In: Biology

Answer 1

I copied this from a previous post where I replied to a similar question,  

Strength is like a tug of war, just having more people on the rope doesn’t help if they’re not all pulling together. Fewer people pulling on the rope in sync, will beat more people who are pulling out of sync.   

Big muscles don’t necessarily mean every muscle fibre is pulling, small muscle that recruit more muscle fibres to pull are much stronger than big muscles that don’t
