Depending on your intensity. I cannot train more than 2-3 times a week as I pulverise myself in the gym. But there has been times, usually after an injury, where I trained 7 days a week and felt fine.
So I guess it's all depended on how you feel. Don't force yourself to train if you feel tired or aching. It's your body sending you a message that it needs rest. We all have different bodies with different levels of fitness/development. There's no right way of doing it. Looking at your program I'd say yes, you're training too much and not resting enough, but if it works for you, go for it. If not, settle for a 3 day a week routine. Gordy wrote a good program in one of the stickies in this forum section. Check it out.
