@irvinespine: Did you know that you have 4 abdominal muscles!? And they actually do more than you think! Your 4 abdominal muscles are: ⚡️Transversus Abdominis ⚡️Rectus Abdominis ⚡️Internal Oblique ⚡️External Oblique Most people don't realize that your abdominal muscles all work together to assist in breathing, stabilization of the pelvis, and flexion of the trunk in different directions. If you really want to improve the function of your abdominals you don't isolate a muscle by doing abdominals crunches. Start working on breathing biologically and core stability vs crunches or bending motions. #core #corestability #abs #abworkout #coreworkout Media Description: Dr.Shakib shows what the 4 different abdominal muscles are.
