Very nice start man! It's nice to see someone w/ the balls to post up honest vids. You've got a real solid foundation and your strength is going to skyrocket on this program.
When I clicked on the row vid, I saw the hammer strength machine and was like, "Oh no, this kid is going to do hammer strength rows." LoL All those pretty machines around you and you just use a barbell? LoL 90% of the people in your gym don't know what the hell a powerclean is and think BB rows will ruin your lower back. Nice work.
Your rows look good. One thing you "might" want to try for, is trying to squeeze/arch the upper/middle back at the top and pull explosively from the floor (i.e., deweight the bar each rep, then pull explosively w/ the lats and try to arch the upper back at the top). Arching the upper back (lower back stays steady) pulls the shoulders kind of back toward the hips, which really makes your lats work. Overall though, looks real good to me. Nice job.
