Once a week is unlikely to do much.
Work-out schedule is quite a personal thing but as general rules,48 hours of rest between training (of an invidual muscle group(S) ) is absolute minimum/necessity and at least in the case for beginners.
However when you advance and start to work harder,more systematically and with specific stress it is reasonable to have a good rest.At this point,coming back to invidual needs...
If there is unbalance,you basically work more with those areas that are lacking for you until comfortable.You cannot,however,increase the amount of training for other groups at the same time since recovery becomes more tricky again.
