That question really requires a little more info to answer correctly! Your age? your ultimate Goal? and your Nutrion intake all are variables! Just to name a few. Younger people have a tendancy to recover a bit faster than us older folks! If your trying to gain. Less frequency and more intense training works well. If your trying to loose weight more frequencey less intense works well.
I personally do a 2 on 1 off split this allows me ample time to recover. As I am always looking to gain. This works out to hitting each muscle group hard once every 6 day. Over the years this is what I have found to work best for my particular body type. Everyone is different and it may just take trial and error to figure out what works best for you.
I would strongly suggest keeping a training log and record every thing. IE sets, reps, bf%, how you feel, and your calorie intake. On a daily basis this is truely the only way you are going to figure out what works best for you! Patience is also important as this take a little trial and error to figure out!
