Working out isn't just about hitting as many chest reps as possible. You need to build muscle in all areas of your body equally. Why? You can prevent

long term injury. If you focus on the chest muscles, then your back muscles—the chest's opposing muscles—will not get the same benefits. 

An imbalance occurs, which means

one side of the body is working harder than the other during weight lifting. If this happens, then you are in danger of muscle tears, various aches and

pains, and joint damage. By working out the opposing muscles equally, you avoid this sad, sad fate. 

A compound exercise is any movement that uses multiple joints. The back exercises that most people use to workout will have these types of movements. Just like working the

chest, working the back means lots of compound exercises. 

These have been proven to release testosterone and other naturally occurring growth stimulants that help you retain and grow new

muscle all over the body. This means you see gains (everywhere) faster. 

So, simple math dictates that if you do these exercises for more than just the chest (like some people),

you are going to see extra results.

This exercise is by far the best thing you can do for you back. It hits all of the major muscle groups of the back. Since you are working

with just bodyweight, it ensures that you're getting functional strength, which helps out immensely in day to day life. 

There are a variety of versions you can do. But the row is definitely the best exercise to use if you want to work out the major muscles

of the back but you can't do a full pull up. 

You can take on the upper back with a row, but that leaves the lower back. Do a deadlift to balance all of your back muscles. It is a

great exercise to work your lower back and hip joints.
