Core

Anatomy

Rectus abdominis flexes the spine; obliques rotate and resist rotation; transversus abdominis cinches the waist and raises intra-abdominal pressure. Neck muscles support posture and should be loaded lightly. A useful core is anti-extension and anti-rotation as much as it is crunching.

Muscles in this region

• Abs

  Rectus abdominis

  The “six-pack” muscle flexes the spine and braces under load. Train both crunching and anti-extension.

• Obliques

  External and internal obliques

  Obliques rotate and side-bend the trunk while resisting unwanted twist—key for a tight waist and athletic power.

• Transverse Abs

  Transversus abdominis

  The deepest abdominal wall muscle. It cinches the waist and stabilizes the lumbar spine under heavy compounds.

• Neck

  Sternocleidomastoid and deep neck extensors

  Neck musculature supports posture and contact sports durability. Train carefully with light, controlled loading.

How to train this region

Pair a flexion drill (cable crunch, hanging raise) with a brace drill (plank, rollout, dead bug). Add a rotation or anti-rotation movement for the obliques. Treat neck work as accessory: slow, light, and pain-free.
