1 Hip muscles. 2  Lunges work all of the gluteal muscles in the hips, primarily the gluteus maximus that is used to extend your hips. 3  Taking large steps during a lunge can further engage this muscle. 4  The gluteus minimus and gluteus medius are also used to stabilize your body throughout the lunge.
The lungs are designed to absorb oxygen from the air and transfer it into the bloodstream. The lungs are found inside the chest and are protected by the rib cage. Between the ribs are muscles that are essential for breathing. The most important muscle of breathing is called the diaphragm. It is dome shaped and lies below the lungs separating them from the abdomen. Two thin layers of tissue called the pleura cover each lung and the inside of the rib cage. These layers or membranes, slide back and forth over each other as we breathe.
