Previous resistance training (RT) recommendations and position stands have addressed variables that can be manipulated when producing RT interventions. However, 1 variable that has received little discussion is set endpoints (i.e., the endpoint of a set of repetitions). Set endpoints in RT are often considered to be proximity to momentary failure and are thought to be a primary variable determining effort in RT. Further, there has been ambiguity in the use and definition of terminology that has created issues in interpretation of research findings. The purpose of this paper was to: (1) provide an overview of the ambiguity in historical terminology around set endpoints; (2) propose a clearer set of definitions related to set endpoints; and (3) highlight the issues created by poor terminology and definitions. It is hoped this may permit greater clarity in reporting, interpretation, and application of RT interventions for researchers and practitioners. Muscle Nerve 56: 368-374, 2017.
