The technical answer is that is takes about 48 hours for your muscles to repair themselves through protein synthesis. So you could you work the same muscles 48 hours after initially working them.
Studies have been inconclusive but there’s some evidence that working a muscle twice a week is ideal for growth and beyond that gets you diminishing returns. But most studies say you want to do at least twice a week because once a week isn’t ideal for gains.
The right answer is everyone has a different thing they works for them. Some people do the same exercises every day. A lot of people are doing a similar one to
@Kontradiction, like a PPL (push, pull legs.) Because I’m a newbie and it’s a buffet for me in this stage and I’m really motivated, I do upper/lower rotating every day.
