Abstract: A core resistance apparatus is provided. The core resistance apparatus is comprised of a rotational adjusting element having a rotational member and a first and a second rotational cord guide. The first and second rotational cord guides pivotally contact a first and a second side portion of the rotational member along a contacting means, respectively. The core resistance apparatus is comprised a first and a second resistance cord. The resistance cords each have a first and second attachment point, wherein the first and second rotational cord guides slidingly connect with the first and second resistance cords, respectively. The core resistance apparatus is comprised of a first and a second upper body connector, and a third and a fourth lower body connector. The upper and lower body connectors attach to a user, wherein the location of the rotational adjusting element adjusts to a center of gravity relative to the user movement.
