It’s obvious you need to know what Core muscles are, core muscles are muscles that run the trunk and torso of the body designed to stabilize the spine, pelvis etc to create a strong support. Thus obviously abdominal muscles are considered core muscles, since you’re working out your abs you are strengthening some of your core muscles.
