Muscle of the Week - Chest

Hi everyone!  It’s that time again…the muscle of the week.  This week I’ve chosen my favorite, the chest.  The pectoralis major and pectoralis minor are what I’m going to focus on.  The major muscle of the chest is the pectoralis major.  This is the larger muscle of the chest.  It’s a fan-shaped muscle that stretches from the armpit up to the collarbone and goes down across the lower chest, connecting at the sternum, or breastbone.  The pectoralis minor is a thin triangular shaped muscle that is under the pectoralis major and it runs up and down the upper ribs.

If you recall my previous muscle/muscles of the week were the shoulders.  The pectoralis major plays a major role in the movement of your shoulder joint and is responsible for four major actions.  First is the flexion of the humerus (the bone of the upper arm), as in lifting a child.  The second, it adducts (moving the arm towards you) your humerus, as if you were flapping your arms.  Thirdly, it rotates the humerus medially, such as arm-wrestling.  Lastly, the pectoralis major is responsible for keeping the arm attached to the trunk of your body.

Though the pectoralis minor is the smaller of the chest muscles and doesn’t seem to get a second thought when it comes to working it out, it is indeed important because it keeps the scapula steady during exercising.  You can exercise it without additional effort because pretty much every workout you do for the pectoralis major, also works the pectoralis minor.

Listed below are three common exercises that I do to work the chest.  I would like to note that on the incline bench press, I choose a shallow angle setting on the adjustable bench, such as a setting less than 45 degrees.  I do this because if you get any higher on the angle you tend to work the shoulders more than the upper chest, which is what the incline bench press is meant to work.  Hope you guys enjoy the routine and if you have any questions about the movements, please feel free to contact me and I will do what I can to answer your questions.  Thanks everyone and have a great day!
