CT, during a specialization phase is the reason to lower volume in other body parts to not build of fatigue or more so that with the available resources your body has you want the the “work” to be done in the target area.
It’s first because the body has a limited capacity to recover from physical stress. A training session has both a local (muscles being trained) and systemic (the whole body) effect. The cortisol release, the energy use, the CNS “fatigue”, among others, affect the whole body. It doesn’t matter if you were trying to build your shoulders or legs, physical stress is physical stress.
The second reason is that there is negative crossover with some muscles. For example if you specialize on your chest, the deltoids (and likely triceps) are still receiving training stress, if you keep the same volume of work for these muscles you might exceed the workload they can recover from.

Does it make a difference specializing based neuro type? Of course I’m specifically curious about 2Bs…
2Bs and 3s are more impacted. They have a higher baseline level of cortisol production and their CNS stays “high” longer after a workout (because they have a lower level of serotonine/GABA which makes it harder to “calm their brain down”), which creates more fatigue. So the systemic effect of training will be a lot more pronounced than for 1As and 1Bs.
Is there any reason that specialization is somehow better suited to a 2B since we are muscle driven?
for muscle specializatio, yes. 2As and 2Bs do the best on muscle spec. 1A and 1B do better on lift specialization
Just about every time this year I start thinking about doing a spec on delts and traps and I can’t stick to it. But I like the idea/concept a lot.
