I'm finished doing 1 rep maxes on just about anything. Personally, I don't really have a need for them, other than to boost my ego. Say I am getting 315 for 12, and 405 for 4, why do I need to put 430 on there and pull something busting ass for one. By the way, I use those two numbers (315, 405) and the number of reps I can do to guage if I'm getting stronger....
