Yes, you can train to failure with other exercises, but for what reason? If the chest is used to being streesed with several hundred pounds more than you would be using with flyes, then new muscle growth is not going to result from those sets. The only reason you might "feel it more" during a fly is because it is an isolation movement.I understand training to failure and beyond is what will help build muscle (with the addition of a proper diet), but at the same time
You can train to failure and past with flys, incline, decline whatever...
Better off in terms of what? Strength and size gains...absolutey. Someone previously said that flyes may help with injury prevention. If that is true, then they may be of some benefit there.Just because you can flat bench more weight then you can with say a db fly doesn't mean your chest is better off.
The incline is a good exercise, but it is not as good as the flat bench for chest development and it is not as good as the overhead press for shoulders. It's more of a happy medium between the two. In Mark Rippetoe's book he mentions that if you do both overhead and flat bench pressing, then there is no need to worry about inclines. Declines allow more weight to be lifted, but they are cheat lifts because the distance you have to move the bar is shortened.
