There is nothing "normal" about my weight at that point if the only way I can keep it off is if I'm measuring out my diet with a scoop and a scale and spending 2-3 hours a day (sometimes more) at the gym. That isn't a normal lifestyle for anyone except athletes, models and body builders, and even a lot of them have more leeway.
You look pretty lean in those pics dude. If you are like me and put on fat easily, then yes it would be a struggle to keep the weight off, even with a lot of muscle.
I've never had to do more than 45mins at the gym though, but I do have to hit the cardio every day to keep bodyfat low.
