Correctly training and developing ones back is vital to both all around health, muscular balance and good aesthetics. The major muscles that make up the back are the latissimus dorsi, trapezius, rhomboids, teres major and minor as well as the erector spinae. In order to fully develop the back you need to work these muscles vertically (pulling down or up), horizontally (rows), and finally in extension. You also want to ensure full contraction by pausing for about a second at the peak contraction point of each repetition.
So you want the perfectly muscled back with the athletic V-taper shape? Here’s how to get it. Do the exercises one at a time, finish all sets and reps before moving on to next exercise.
