When you bend your leg the rotational inertia is greater you leg is?

When you bend your leg, the rotational inertia decreases because the mass of your leg is brought closer to the axis of rotation (your hip joint). Rotational inertia depends on both the mass of the object and the distance of the mass from the axis of rotation. By bending your leg, you effectively shorten the distance between the mass and the axis, resulting in a lower rotational inertia. This allows for easier and quicker movements of your leg.
