Back Strengthening exercises will help you improve your maxes on most other upper body lifts. It is very important to train your back muscles for posture because most of us sit all day long at work, and our shoulders tend to roll forward.

Benefits of back exercise :
. Latissimus dorsi, the large muscles that originate below the armpits and run down the back of the ribcage and are responsible for shoulder movement .
. Rhomboids, muscles located in the mid-upper back that are responsible for retraction of your scapula, or shoulder blades .
. Trapezius, which runs from the neck to the middle of your back and is responsible for the movement of your shoulder blades .
. Erector spinae, muscles that run along your spine and control extension and lateral movement .
Strengthening your back also helps you if you just enjoy heavy weight training. When your back muscles are strong, they’re better able to assist you in conducting other lower body lifts, such as the squat.

. Improved Posture
It can be a difficult thing to keep up, especially if your back muscles are lacking in strength. However, if you have worked on making your back stronger, it becomes easier to maintain healthy posture.
You’ll experience less fatigue, and in time you may even find that your physical health allows you to keep up good posture without even having to think about it.
. A Strong Back Looks Great!
A strong, healthy back can help you to not only feel better, but look better as well. When your back is in good shape, it helps with posture, symmetry and much more. Because of that, it’s also helpful for ensuring that you have a healthy core.
A strong back also makes exercises for other areas as well, allowing you to achieve an overall great look.
