Tip from a fellow newbie (or 'cool novice,' as it were)...
That's what I've been doing for the past month. It worked fine for me -- I really needed the time off between workouts and the several days between squats or deads because I wasn't used to such hard work - I had lots of soreness and tiredness. If I had to face the weights more than three times a week, I might have slacked off and then quit...
Now the split is starting to feel more like a 'template' than a training program (which would be aimed and improving my particular weakness and reaching my particular goals), so I'm tweaking it to suit my needs more. I don't think that says all that much about the split itself, just the learning process..
So, what Spatts said: try it and soon you will see - you can't pick the 'best one' before you try it on!
That is the exact same muscle group pairings i use, but i have leg and back day in reverse order of what you do, i found that switching to that method really brought up my quads and delts, hope it works well for you.
I use the same split, except I also have my leg and back day switched on wed and Fri.
A lot of people who workout think that more is better. With weights it is not really the case. Resting seven days between working each muscle group is fine, as long as you push yourself and work hard.
I see people in the gym working the same muscles over and over throughout the week (usually upper body: bench press and curls). I can't figure these people out. Dont they care about the rest of their physique??
