I have been training serious for about 18 months. For the last 6 - 8 weeks, whenever I train my back, my lats are never sore the next day. Conversely, when I train my chest/legs/delts, I am sore the next day.
I have tried to vary my routine/reps/volume/cadence. But still my lats feel normal the next day.
Can anyone suggest a back routine, specifically targeting the lats (upper and lower) to stimulate growth?
Furthermore, does the trained bodypart have to be sore the next day in order to acknowledge that I have trained properly?
You anticipated response(s) is greatly appreciated.
