To do the one-arm Row as your tenth exercise do 5 on each side (each arm). – I like to tweak this great strength move a bit so that you get more core involvement.
Keep both feet even on the ground (other versions have you put one knee on a bench), and reach onto a bench or other secure object. The goal is to get the back flat and parallel to the ground. Grab a dumbbell or other implement with the other hand and pull it to your side, getting your elbow as high as possible.
