Recently, Schoenfeld et al. (31) set out to update the previous meta-analysis (18), given a plethora of new research on the topic since publication of that paper. The researchers chose to analyze volume on the basis of the number of sets performed per week per muscle group, surmising it to be a more relevant measure of training volume. A total of 15 studies meeting inclusion criteria showed a significant benefit to performing higher versus lower training volumes. Moreover, a clear dose-response relationship between the number of sets per muscle per week and muscle growth was found when RT volume was stratified into
