Gym training for distance swimming

Hi. I'm trying to put together a bit of a program for when I go to the gym. I'm most interested in 400m and 1500m performance but also 200m. I'm looking to find some articles or information with regard to what sort of training to be doing in both dryland cardio fitness and strength work. I remember reading a while back some material about various workout levels (iirc AN1, AN2, AN3, etc) and how you should be working with that for distance swimming, but I can't find it any more. I've got an appointment with the gym's personal trainer and want to be prepared to explain exactly what I'm looking to get out of my gym training. Can anyone help me? Thanks, David
