I'm currently doing the Bill Starr 5x5 and it says under no circumstances train to failure. I don't and I haven't. I got the impression that the writer also doesn't train to failure and he thinks it's one of the reasons why he's so strong. Why is training to failure wrong? I'm asking this question partly because I'm probably going to do GVT after I'm done with the 5x5. That program seems like it's built for failure. What are your thoughts?
