Exercising takes a really long time. Is it possible you're doing it wrong, or maybe we have different understanding of what "really long time" is? I exercise 4 times per week, and my workout lasts 40-60 minutes including shower and clothes change. This includes pre-workout stretching, strength training and some static / balance exercises. I try to use my time as effective as possible, so I'm almost never idle. I superset my exercises, i.e. do a rowing exercise, immediately followed by a pressing exercise. But some rest is still required, so I do a stretch or a balance exercise, i.e. working on handstands while resting. This lets me include 6-8 exercises for 2-4 sets each in about 30-40 minutes. Now you may say 4 hours per week is still too much. If I was seriously pressed on time, I would reorganise my training to only exercise each body part at most 1 time per week, thus combining 4 workouts into 3 shorter or even 2 longer ones, bringing the time down to 2.5-3 hours per week. I may stop exercising smallest muscles, such as biceps, directly. Anyway, following my schedule I consider myself in a very good shape for 41, I'm 178cm/74kg, around 10-12% bodyfat if not less, can bench about 1.3 times my bodyweight, squat over 1.5 and deadlift over 2 times bodyweight.
