shakastrong knows core strength!

Core strength refers to the intrinsic muscles that lie deep within the torso. These muscles attach to the spine and pelvis and include the transversus abdominis, and the muscles of the pelvic floor in the lower portion of the torso and the latissimus dorsi and obliques in the middle and upper torso.

Your core provides strength and stability for the rest of your body, which is why it is important to develop these muscle groups.
