Eli5: Lifting more weight without building more muscle

842 viewsBiologyOther

Bit of a weird question. How is it that that people gain strength without getting relatively bigger or more muscle.

Imagine I can bench 100kg or 225lb for a 1 rep max. Now imagine I train hard and now can lift the same weight for 3 reps.
Its unlikely your muscles have gotten three times bigger.

What has actually changed in the body to enable this?

iirc depending on genetics and the type of training you do muscle fibers can either get larger or become more dense
