Corn & B True:
You answered your own question... Many powerlifters don't train all three, core lifts on the same day because it is very difficult. I don't disagree with either of you about hitting all three lifts in the same training session because this does simulate a meet. But, many powerlifters break up the three, core lifts when training much like many bodybuilders break up their muscle groups because it allows one to focus on a particular movement. Great powerlifters and bodybuilders were developed using both the split and total-body training. I have trained all three core movements in a single training session in the past and it can be a very humbling experience. It is an excellent question, Corn, and deserves some serious thought by all strength athlete competitors. B True is a prime example of someone who has made tremendous gains by training his entire body in a single workout. IMHO.
