Tiptoe acts as a first-class lever because it has the fulcrum located between the effort and the load. In this scenario, the ball of the foot serves as the fulcrum, the effort is applied by the calf muscles through the Achilles tendon, and the load is the weight of the body. This arrangement allows for efficient lifting and movement, enabling the body to rise onto the toes with minimal effort.
