How much is too much!?!?!?!?!

I've been seeing a lot of posts from people who are doing like 2+ hours of cardio in one day! Is it me or is this excessive?! I was always of the mind set that 45 to 60 minutes of a good cardio burn is enough. Maybe I'm just a slacker lol. But quite frankly I just don't have time in my day for 2+ hours of a work out especially if in addition there's travel time to and from the gym. Just looking for other opinions.....
