Shoulder I lower my ON volume?

[haulinbass]

I'm just wondering what you guys thought about my training routine. Off cycle I usually train 3 days per week for about an hour. On cycle I always have trained 5 days per week, I have had pretty good results with that everytime so far. So I been reluctant to experiment with my preciousness ON time and try lower volume less frequent routine. But I'm curios to as if I would get just as good or better going down to 3 days. Something like Mon-Chest/Shoulder/Bi, Wed-Legs, Fri-Back/Triceps

On I do something along the lines of this although I change some lifts and reps everytime. My big lifts I usually keep the same for the most part. Wondering if you guys thought this is overtraining.

You could try this approach:

mon-chest/triceps
tues-back/biceps/forearms
wed-legs
thurs-shoulders

thats what i do. that way you can eliminate that 5th day for more recovery time.
