A big, strong upper body has always been the baseline for bodybuilders and fitness enthusiasts. From a wide chest to a pair of round shoulders, these muscle groups set the stage for your physique. Sure, abs are always a popular muscle to build up — but how often are you walking around with your shirt off?

When you’re building your body, you need to be practical, and strength comes from the arms. So let’s dive in to the basics of building bigger arms.

First off, it will never happen overnight. Those coveted, muscular arms take a lot of work and dedication. But with patience and perseverance we can help you build bigger biceps, stronger forearms, and powerful triceps.


The bicep muscle consists of two muscles the short head bicep brachii and the long head bicep brachii. Both of these heads extend from the scapula, which is often referred to as the shoulder blade, to the forearm.


The tricep is the large muscle on the back of your upper arm, directly opposite of the bicep. Think underarm flab that jiggles around when you shake your arm. The tricep is comprised of three muscle heads. The long head, the lateral head, and the medial head. Each of these heads work independently of to extend the arm from the elbow joint.


The forearm is as single muscle that connects the hand to the muscles to the upper arms. This muscle can be separated into two parts the anterior and posterior or front or back. The muscles in the forearm contains many muscles that pretty much responsible for controlling the hands and fingers. The strength of your grip is directly related to the strength of your forearm.

Understanding the arm and the muscles that allow the arm to function is important to building bigger arms. Breaking down how each muscle interacts with one another we can now take a logically approach to training them properly and how to get bigger arms.
