I thought the same as you, and set up a home gym in response, which saved me half an hour's commute. After 4 years I'm going back to the gym. I found that being surrounded by cardio bunnies and muscleheads actually motives me, especially when you see people twice your age in better shape than you. As with everything else, such as sleep and nutrition, you give it the time you think it deserves. If you put your health behind other priorities, no complaining when your body gives out before its time. And finally, everybody and every body is different. I've found that a one hour weight training session three times a week is enough to maintain my current muscle mass (which I've earned the six years prior to switching to a maintenance workout). You might find that you need less than an hour a day once you get your body in shape.
