ELI5- Do muscles grow and physically appear during a workout or do the effects take place in the time afterwards?

284 views

I’ve wondered this for so long but don’t know how to articulate it well and also feel like it’s potentially a very dumb question but thought this would be a good place to ask it.

Essentially- while I’m working out, are the muscles building themselves during that time or is it a situation where you’d be able to see the effects afterwards like in the coming days? I hope that makes sense.

The body is constantly growing/replacing itself. When you work out it increases this growth, and for some time after. During your workout it won’t have any significant impact. Any growth during the exercise is probably just due to swelling or increased bloodflow.
