If you are eating enough to support it, training longer than an hour may not hurt you. However, this is highly individual. I just got back from training my back. It took me about 45min and I was wiped out. If I had thrown in another body part it would have been trained with much less intensity as a result. I didn’t stop at 45min because I thought I had trained too long. I stopped because I was done.
I’ve known some guys who can make progress training several hours a day but they are the minority. The ones I have known also eat like a rhinoceros when they aren’t in the gym, much of it not “clean” food. They just compensate for it with the weights lifted.[/quote]
I have to eat a LOT on training days(as do all of us) before I go to the gym, but not because I won’t grow, but because otherwise I wouldn’t have enough energy to get through the workout. Coupled with cycling 5 hours a week it (1 hour a day), it makes it quite hard to get all the calories in a lot of the time.
I usually train anywhere between 45min and 2 hours, some workouts obviously take longer/shorter as others have pointed out, but it is absolutely individual. I tend to also take slightly longer breaks between sets, so this adds to total time taken.
Most of the time though, the guys that make the least progress (from what I’ve seen), are the guys that are in there for less than 30 minutes. This one guy has been going to the same gym as me for over 1.5 years, and he looks EXACTLY the same, skinny self he did as when he started. He barely works up a sweat, and he’s always in and out in under 30 min. He’s not the only one.
