Yeah...for years I heard, do not work out the same muscle two days in a row. Give the muscle time to repair. But recently I read something that said, its okay to work out the same muscle everyday, ignore the whole recovery rule. If you think about it, it does make sense though. Think about big construction workers for example, picking up heavy pieces everyday and they get huge (I know my friend did). Those guys do not take no "recovery days," except for weekends maybe.
I personally still give my body recovery days because I try my best to avoid injury. I never want to over-train and then get hurt. If you do decide to workout a muscle everyday make sure you get A LOT of protein or else you're not giving your muscle the best chance to repair quickly.
