Exactly. Train everything 2x per week (6 days total) and take Sunday off. I have gotten my BEST results doing this. I have steadily added muscle while staying lean. I would not necessarily do this for strength, but for adding decorative muscle, this program has me sold. Keep in mind, I have been training steadily since 1984 and have done just about every routine out there. For adding muscle AND staying lean...nothing has come close to touching:
PUSH/PULL/LEGS/PUSH/PULL/LEGS/OFF
then repeat week after week, month after month, year after year.....
I do take a week off 2x per year. So I generally follow this for about 50 weeks a year. Some weeks I might only get in 5x... I never go less than 5x per week. I would say 90% of the time I lift 6x per week, one hour per day.
This is exactly what I do and I've had my best size gains with it as well.
