Your arm can be considered a first class lever.
The biceps brachii acts as a class 3 lever to flex the arm. The deltoid also acts as a class 3 lever to abduct the arm, as does the teres major in adducting the arm. The triceps brachii, however, acts as a class 1 lever to extend the arm. In other words, when you're bending your arm or swinging it toward your body or away from your body, it's a class 3 lever. But if your arm is bent and you're straightening it, then your arm is a class 1 lever.
The class 3 lever always has a longer resistance arm than the force arm. This is because the distance from the Fulcrum to the load/resistance is always going to be further that the fulcrum to where the effort/force is applied. If you look at a diagram of a 3rd class lever, you will be able to see why this is.
first class levers actually in front of the effort and resistance forces

A Human arm is a class-3-lever .Because the load is located by your fingers and the effort is by your elbow and the fulcrum is by your shoulder.
