One question particularly common amongst those just starting out in body building and muscle bulking is about arm muscle building.
It seems that the most common areas people like to embark upon improving in the early stages of their body building is the arms.
But arm muscle building is not just, contrary to what some newer bodybuilders seem to perceive, about lifting your arm up and down with a weight in your hand.
In fact, the arm is made up of three main muscle groups and if you do not understand those, then arm muscle building will be an uphill challenge for you.
Those groups of muscle in the arm are: -  Biceps Brachii - These two muscles are located on the front of the arm and run from shoulder down to elbow.
- Triceps Brachii - This is a group of three muscles which also run from the shoulder to the elbow, but this time on  the rear of the arm.
- Forearm - This is a group of several smaller muscles which run from the elbow down to the wrist.
Different exercises tackle and improve different muscle groups and in order to have the bulky arms you desire, you will need to work on them all.
Exercises that improve the biceps include the standing barbell curl, preacher bench curls and alternating standing dumbbell curls.
These should be done in sets of around ten - fifteen repeats and start with just a couple of sets and improve as you can.
In similar quantities, close grip bench presses, dips and EZ bar lying extensions will work the triceps and EZ bar reverse curls will work out the muscles in your forearm.
So as you see, there are three areas within the arms alone to consider.
And remember to increase the quantity of each exercise gradually.
Going too quickly will only lead to injury.
