Hi colleagues,
why some phases are called Developmental and the others Specialization? What are the criteria?
Specialization typically describes a phase of training with a high degree of specificity towards a particular performance test, such as a 1RM effort in specific lifts. Developmental phases are more general, with lower test-specific training and more variation in movement selection, rep ranges, and intensity ranges.
agree, it’s by definition. But what makes some methods test-specific, especially if sometimes hey look quite similar? E.g. in beginner template 1@8, 4x3 as a backoff work is Spec phase, in Bridge 1@8 + 4x3 is Development phase. I would suggest that it could be lower load for backoff work (78% vs 80% 1RM for Bridge), but in case of HLM template, similar percentage like in Bridge is treated as Spec phase… 
Is there any general principle or is it just a sort of art?
How the main approaches to loading (I: 5@6+5@7+5x3 @8 vs II: 5@7+5@8+5@9+5@(-10% from 5@9)x3 vs III: 1@8+5@9+20 reps in sets of 4-6 q75-80%%1RM) relate to Dev or Spec phases?
Hm, my question looks bothering, sorry for that…
There is no specialization phase in the Beginner Template. That said, the design of the entire program should reflect the desired adaptations.
I’m not sure what you’re asking, but their are differences in volume, average intensity, and likely fatigue in all three protocols. All three could be used in either phase, as they are not definitively one or the other. There is quite a bit of overlap.
Got it. Thank you
