Question about rest?

[jumpman23]

I was wondering why you should only workout a muscle group once a week? It doesnt seem like the muscle group would need 6 days to recover. But i'm a dumb newb, so help me out.

It can take 6 days if you train hard enough. Muscles build at rest, be careful not to over work them.

I only need/use 4 dayz to recover, everyone's different, just dont go workin your chest out 4 times a week
