In fitness one of the prime attractions is a nicely defined flat tummy also know as washboard abs, but in this article I would like to focus on The abdominal muscles anatomy and Functions of the abs. Once you know how to pin point the location and function of individual ab muscles, you can focus on those muscles more effectively and get the most results out of your ab workout. With that in mind, let’s take a closer look at the major abdominal muscles. There are 4 main muscles in the anterior (front) abdominal wall. These are the rectus abdominus, the external oblique, the internal oblique as well as the transversus abdominus.
(1) Rectus Abdominus: The rectus abdominus is probably the most popular and recognized ab muscle because this is the muscle that makes up the famous 6 pack. The rectus abdominus runs straight down the stomach and attaches the ribs in the direction of the pelvis. It works really hard while you perform crunches and sit ups or any other exercise in that your vertebrae bends forward against resistance. The rectus abdominus is primarily a mover of the spine, but in addition it facilitates to stabilize the pelvis and lower back.
(2) The External Oblique: The external oblique is located on both sides of your waist. This muscle goes diagonally from the back of your lower ribs down to your pelvis. The external obliques on both sides work to help your spine bend forward similar to in crunches and sit ups, so when you so crunches all of your ab muscle groups work. However, if you want to emphasize the obliques you need to incorporate twisting, rotation, or else side-bending. When you turn your legs to the side or twist your body at the top part of a sit up or crunch your external oblique muscle will work harder than during a usual crunch.
(3) The Internal Oblique: The internal oblique is located underneath the external oblique. It goes diagonally from the pelvis up to the lower ribs. Just like the external oblique, the internal oblique works during regular crunches, but it is stressed by means of twisting or else rotation. The internal obliques are constructed more meant for stability since they are deeper moreover closer to the spine. Isometric side planks are a excellent exercise for the internal obliques.
(4) The Transversus Abdominus: (also called transverse abdominis or TVA).The fourth abdominal muscle is the transversus abdominus. Although it is the least popular muscle, various physical therapists think it as the most significant muscle. As the name suggests, the transverse abdominus works across the abdomen. It is the deepest of all the abdominal muscles, and because it is so close to the spine it is the major abdominal stabilizer of the spine. The transversus abdominus does not move the spine forwards or assist it to twist and rotate. The only function of the transversus abdominus is to stabilize the vertebrae and stop it from moving. Sometimes the transverse abdominus is referred to as your natural girdle because it acts like a girdle to keep your stomach pulled in. It will work during every movement as well as every ab exercise, but you can highlight it via pulling your belly button towards your spine.
All of the abdominal muscles have a distinctive function, and all of them are significant. In a fitness program, I recommend that you take an integrated approach and focus on different forms of physical exercises to condition all of the abdominal stomach muscles anatomy.
