Why is the rotational inertia greater for a gymnast when she swings by her hands from a horizontal bar wit?

Why is the rotational inertia greater for a gymnast when she swings by her hands from a horizontal bar with her body fully extended than when she executes a somersault with her body fully extended?|||Conservation of Angular Momentum. (Radius of stretching ) ^2 x Angular Frequency = const.|||Rotational Inertia = 1/2 M x r x r (half - M r squared)





So If gymnast is extending her hands, the r (radius of rotation) increases which increases the inertia
