Training volume has a relationship with rates of hypertrophy in research. But how do you quantify volume? Further, just because a group doing more volume often grows more than a group doing less, does that mean your volume needs to increase? When should volume increase? Are there times volume increases are counterproductive? What are the fundamental differences between increasing load or reps, and number of sets? In this episode we break down hypertrophy, progressive overload, progression, and volume from a first principles perspective, ultimately helping you understand the answers to all of these questions.
