Major Muscle Groups: Arms, Chest, Shoulders


Though we have hundreds of muscles in our body, most of which are secondary supporting muscles, in order to design a good strength training program, we need to focus our attention on our primary, voluntary muscles. This means we’ll have to volunteer to use them if we want them to grown stronger and more flexible.

Ladies, stronger doesn’t have to mean bulky. Besides, more muscle means less fat. And strong is sexy! Physical strength can take a normal, insecure female and turn her into a confident and powerful woman from the inside out! Rowr. Who wouldn’t want that? And let’s not forget about that involuntary muscle – the heart. A great strength training program is great for that muscle too!

In today’s post, we’re going to focus on three of the major muscles groups of the upper body, found in our arms, chest, and shoulders.


The two primary muscles found in your arms are biceps and triceps.

Biceps_TricepsThough relatively small in size, the biceps draw a lot of attention to the upper body and using them regularly can help get rid of arm flab. You can call them guns, pythons, or weapons of mass destruction if that helps heat up your workout mojo.

The triceps make up about two-thirds of our upper arms and, when properly developed, they can aid greatly in the elimination of those dreadful bat wings or premature arm jiggle. Jiggle, jiggle….


Pectoral MusclesThough hidden under the breasts of  females, chest muscles, also known as pectoral muscles, are pretty obvious on males. (The more obvious, the more sexy. Rowr. Whew, moving on….) If you think about it, chest muscles have a pretty important job. They are the main muscular structure that protects the thoracic cavity, home to our lungs, heart, and parts of our digestive system. It makes sense that the stronger and healthier our pectoral muscles are, the stronger and healthier our internal organs and muscles will be too.


DeltoidsThe shoulder joint has the largest range of motion in the human body. Because of this, it is also the most unstable joint and is very susceptible to injury. How can we better stabilize such a flexible joint? You got it, strength training. Stronger muscles make for stronger joints. Not only that, but as a female, shoulders are my favorite upper body muscle to shape and show off. Attached to the very feminine collar bone, they can take any tank top or strapless dress to a whole other level. Bonus.

Shoulder muscles, also known as deltoids, are composed of  three different parts: anterior (front), medial (middle), and posterior (back). Often, the posterior deltoid gets left out of a upper body workout and it gets sad, but a good shoulder workout will work out all three parts of the shoulder.

To Be Continued….

Well, folks, that’s enough for today. Come back next Saturday for another lesson on major muscle groups, this time focused on those important, though often overlooked, back muscles.
