You can but if your training them right you won't need to

Yes, chances are you'll see progress quite quickly if you're only doing once a week currently.

I think first we would need to know if you are training for strength or size.
Most strength athletes train their body parts more than once a week.
Plenty of bodybuilders only train their muscle groups once a week.

10 days, one muscle group per day and rest between days. Works for me but I'm 40. Ha!
