I don’t like the rep/set scheme here much, but this is where the exercise selection came from:
In the event the link gets removed, there was a four part series on back training published I don’t know when. Four contributors: Samuel Homola, John Grimek, Ron Lacey, and Dominic Juliano.
Juliano’s piece covered lat training specifically, and given Alternate’s post history, with his difficulty with MMC in general, and his concern about putting too much pressure on his lower back (doc told him he couldn’t ever squat/deadlift again, or something like that), I picked three of the exercises Juliano suggested that should at least help him feel the lats working, rather than the biceps. I dropped the one-arm row because too many people still end up using biceps on that until they get some MMC down (myself included).
JM’s or CT’s exercise selections are probably great too, however I haven’t tried them. I’m sharing what I’ve tried, and what’s helped me, especially with the problem of hitting lats and minimizing bicep involvement.
Does it answer the pre-fatigue question itself? No. Does it provide a few things to try to start getting the back to move the muscle? Sure.
If it helps, great. If it doesn’t, there goes a whole 15 minutes of experimenting in the gym to see if he can get the back actually moving the weight.
