Ever puzzled over training volume and its role in hypertrophy coaching? We break down the concept into bite-sized pieces and draw the connections to muscle growth. The mathematical formula of reps, times sets, times weight lifted appears simple, but its application requires more finesse. We bring in the often overlooked element of set intensity, and discuss how it's essential to attune your programming to it for maximum results. We press on with the crucial role of mechanical tension and intensity in training volume for muscle growth. Navigating the concepts of RPE or RIR, we illustrate how they can help manage your training intensity and volume.In the final stretch, we dissect the concept of progressive overload. We stress the significance of expanding boundaries beyond comfort, advocating an increase in intensity instead of the constant addition of weight. Recognizing the signs of over-training and under-training can be a game-changer, and we guide you on how to spot them. We also venture into the concept of training age, and how it can help gauge when more volume is needed.
