Continuing from Part 1 where I looked at the concept of muscular/task failure in general, Part 2 of what is rapidly becoming an overwritten series began looking at what muscular failure represents in the weight room specifically. There I defined different muscle actions and types of muscular failure noting that I’d be focusing on concentric muscular failure. I also looked at the concept of the sticking point and how it impacts on all of this.
In this part I want to continue that discussion and look at some of the actual definitions of muscular failure that have been used in the weight room over the decades. As importantly I’ll look at what the implications of each might be in both a practical and research sense. However, as promised in Part 2, I want to start by looking at the concept of the Repetition Maximum or RM.
