Did you give yourself a nice rest from the gym before this cycle? Some people think that the more time you spend in the gym is better than giving yourself a break and that's completely false. I think you were over training as well.
Have fun w/ your workouts. I know it looks silly when working bi's to put 10lbs on each side of the barbell, but try curling it 50-75 times followed w/ v-bar pushdowns 50-75 times. If you don't feel a pump after 2-3 sets of that you're dead. Same w/ any other bodypart. Then next exercise go heavy. Even simple things like supersets w/ dips and chin ups are fun. Use your imagination and keep the muscles guessing.
I haven't had a solid routine in years. Well, what i'm saying is that i never know exactly what i'm going to do before i go to the gym. Only thing i know is what bodypart(s) i'm working that day. Keeps things nice and simple.
Good luck.
