I hit the gym pretty often. When I work out, I usually go three days straight and then take a day off. I always do chest and biceps together. The next day, I do back and triceps, then legs and shoulders on the third day. I do 20 or 30 minutes of cardio before I start, depending on how I feel. I've been doing it that way for years, and I've gotten great results.
What's yours like?
