This document provides instructions for performing several back exercises, including wide-grip chins, close-grip chins, lat pulldowns, bent-over barbell rows, bent-over dumbbell rows, and T-bar rows. Each exercise is described in 1-2 paragraphs covering its purpose and proper form and execution. The goal of most of these exercises is to widen and thicken the upper back muscles, especially the lats, as well as to develop other back muscles like the serratus and lower lats. Maintaining proper form by keeping the back straight and head up is emphasized.
