The Erics are back, and this time, they work through a mental model of how training volume, or rather, the training dose changes over time. With a rank novice, a single set to failure done once per week will typically produce continued adaptation, and they won’t plateau for 1-2 years! However, if you take an advanced strength athlete or bodybuilder, a single set to failure done once per week seems to not only be insufficient for measurable progress to occur, but is even lower than doses that result in small losses of muscle mass. So, it seems the that the minimum effective dose of training changes as one reaches higher levels of training status. But does this mean volume needs increase with training status? Not exactly, but that depends on how you define “needs.” There is an interaction of these concepts with the minimum detectable change we can notice, our goals, the timeline we wish to achieve them in, and also the slowing rate of progress that naturally occurs as one gets closer to their potential. Can the Erics reconcile these complexities into a defensible mental model of how the needed training dose changes over time? Tune in to find out!
