Rounding My Back on Pull Throughs?

Training Powerlifting
1

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.

I’ve seen them done both ways. EFS style is indeed rounded back, essentially reaching as far through your legs as possible.

You can also do them more like a good morning. Obviously the source of the resistance places a different stress on the posterior chain than a good morning or RDL. I still feel these in my lower back, albeit without getting that crazy pump.
