The Back contributes to the overall shape of your physique ~ A well defined V-shaped back gives a smaller looking waist. In addition to looking better, the result of training your back also adds strength in lifting for everyday daily activities. A strong back determines your posture. Your lat muscles keep your shoulders from slumping. No training program can be complete without a great back workout.
