More than mirror muscles

Many guys who want to get in shape want 3 things. 

1. Big arms

2. Big Chest

3. Ripped abs

The problem? You have muscles in your back too and not training them as hard or harder than these mirror muscles can have detrimental effects on your bodies overall strength and look. You've seen the lad who come in the gym and bench, then bench some more. Well next time you see them look at their posture and you will notice the way they stand reminds you of a gorilla. This is because all that bench work and not enough chest work has wound their chest so tight it rounds their shoulders and gives them a hunchback posture. To avoid this you need to work your back the same amount or slightly more and you also want your chest and back to be of equal strength or your back be stronger if you can. This will help to draw those shoulder back to where they should be and avoid injuries that can come with overstretched back and rear shoulder muscles. Also if you have a slight hunched posture it is important to get this sorted before you start to work on your chest, again to prevent injuries and give you a taller, broader posture. The other part to this is that you want to make sure you stretch you muscles to prevent them from tightening up after your workout.
