Happy Monday!

Is it February already? This month we are dedicating the blogs to our arms. Before we talk about exercises to help improve the muscles in our arms, let’s look at the anatomy and the muscles themselves.

The arm is comprised of about 24 muscles. For time’s sake, and to keep us from getting confused or overwhelmed, we’re just going to talk about the “most popular” ones.

Biceps Brachii

The biceps are the muscles we tend to think of first when we think about the muscles in our arms. This muscle helps us to bend our elbows and flex the forearm. This is a movement we perform all the time, so strengthening this muscle is very important.

Triceps Brachii

The triceps are located at the back of the upper arm. This muscle is an opposing muscle to the biceps brachii, which simply means it is located opposite of the biceps. The triceps help us to extend our arm in order to straighten it. This is another critical movement when performing activities of daily living. Also, strengthening this muscle helps to reduce that arm flab we women hate so much (take note, ladies!).


This is the muscle group you have at the top of your arms (shoulders), and it consists of the anterior (front) deltoid, the posterior (back) deltoid, and the lateral (side) deltoid. These different parts of the muscle help us to internally and externally rotate the shoulder while also abducting (moving the arm away from the body) and flexing the shoulder. The deltoids play a critical role in helping us reach up high, and when you work the deltoids, you gain definition in the muscle to, in turn, help you feel confident enough to sport that tank top!

All of this lingo may be a bit confusing, but it is important to know what muscles you use during your daily activities and why is it important to train the muscles to become stronger and more usable. Also, who doesn’t want to know what muscles to work in order to sculpt sexy arms?

Below are a few pictures to help you get a better understanding of exactly where these muscles are located in your arms. In our next blogs, we will talk about what exercises to perform in order to sculpt amazing arms that will show everyone just how strong you really are. Welcome to the gun show!!

Stay motivated, and have a fantastic week!
