Stand with feet shoulder-width apart and grasp the Smith machine bar with a pronated (overhand) grip. Hinge at the hips with a slight knee bend until your torso is nearly parallel to the floor, keeping your back flat and core braced. Pull the bar toward your lower ribs while squeezing your shoulder blades together, then lower it back down with control.
Log your smith bent over pronated grip row sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
