expansion of nerve recruitment?
ok so yesterday was the first time I really started feeling like i was lifting heavy on DL's... big PR, etc.
by the end of the workout, there were places in my lats I could feel before that I couldn't really engage before.
This morning I can feel the same thing. my right lower lat actually cramped up when i got out of bed... mostly fatigue... but i haven't ever really felt this level of muscle activation before. i assume my left side will catch up with my right once that side evens out in terms of development.
i've read that one of the first improvements to strength is in the efficiency of muscle fiber recruitment as your nervous system adapts. could this be what im' experiencing? my body is starting to fire muscle fibers i've never really even used before in order to adapt to the added stress?
It literally feels like i have a new muscle added on to my body that wasn't there before.
