There are three components of a lever system besides the lever arm: the fulcrum, the force, and the load. There are also three types of levers called class 1, 2, and 3. Class 1 is where the force is on the opposite side of the fulcrum as the load. Class 2 has load between the fulcrum and the force, and Class 3 has the force in between the fulcrum and the load. In the body, the fulcrum can be one of many joints, such as an elbow, knee, or ankle. An example of a Class 1 lever would be a tricep extension, where the tricep on one side of the elbow moves the load held by the hand on the other side. A Class 2 example would be a calf raise, where the weight of your body is focused between the calf and the fulcrum (the ball of the foot). A Class 3 example would be a bicep curl, with the bicep in between the fulcrum (elbow) and the load (hand).
