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

294 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 answer is both.

After a workout your muscles will temporarily appear enlarged. This is due to an increase in blood flow to the area.

The muscle physically grows in the days after a workout when your body is recovering. It grows a very very small amount, but it does grow. Compound this effect for 6 to 12 months and you have significant muscle growth
