I'm sorry, but a gym-rat spends 7 days a week 52 weeks a year in the gym. Anything less and you're a part-timer.
I'm 5 days a week, with 30 minutes of cardio plus about an hour of lifting.

My body needs rest, and the weekend is perfect.

I'm putting together a home gym that is pretty cool. Just got a squat/calf machine that takes the pressure off the knees and back. Also got a separate calf machine.

I'd love a crossover cable system but they take up too much space for my taste.
