I'm gonna take a wild guess, is that for an hour a day you do push up's and curls till you can't do them anymore, and you keep doing that for an hour. So tons of sets till failure in one hour. I guess if that's what you got to do for exercise then do it. You'll get tired of that pretty quickly. It would be better to join a health club and do circuit training on all the machines, you'll work more body parts, increase muscular endurance, and your cardio output. That seems to be the type of training you are looking for. And to answer your question i wouldn't do max out reps myself, maybe the last exercise as push ups on my chest day, but not for an hour routine.
