I’ve been following the 12 Week Beginner Westside program found in the EFS Basic training manual for a few weeks now and it calls for 3 sets of 20 reps of cable pull-throughs.
Am I supposed to be rounding my back when I do these? I find I get an insane lower back pump and I’m sore for days. Never enough weight to strain, just intense feeling of lactic acid.
EDIT: Never mind I just watched a couple videos, I’ve been doing it all wrong.
