Ok I was recommended to try out the Sumo DL since I've been experiencing lower back pain from the conventional DL. I unfortunately have APT which makes it a bitch to make consistent gains on Squats & DLs, though I have been stretching consistently & my APT has alleviated significantly but my posture isn't sufficient yet. That said, I'm not sure if my form on this variation of the DL is correct. I followed the advice from this video: Whenever I do the sumo, my mid to lower back is very, very slightly sore/uncomfortable but not as severe as the conventional DL: I've been doing Sumo for the last 5 workouts (specifically for the DL obviously, I follow Stronglifts 5x5 so DLs are every other workout). Not sure if I should continue with this variation or revert back to the conventional DL. I just ordered a legit Powerlifting belt from Amazon (90% or so 5 stars out of 300 reviews) so it could aid in the soreness/discomfort when doing this version. *Edit: Apologies if anyone has trouble viewing the vid. I had trouble publishing it on YouTube yesterday & it was listed as "Private" when I went back to edit it this morning. Switched it to Public so it should play, opening it up in YouTube works if it doesn't play on the forum.
