One of the methodological advantages of Block Training, which by the way far pre-dates any work of Poliquin’s, is such that morphological integrity is accounted for and attended to throughout the sequential loading.
Regardless of the model that is followed, in reference to the founding/pioneering authors, the commonality between the various block models is that each block serves as a prepatory mechanism for its successor.
That being said, in my view, any physical preparation coach worth their salt better damn well account for the stress yielded to, and the adaptation rates of, the musculo-tendonous-skeletal apparatus in the planning of the training.
Unfortunately, my view is an ideological one as I speak from experience, as a coach in the field, when I state that far too many coaches are, in fact, not worth their salt.
