Body Details: Male Arm Drawing Techniques!

When you are doing a male arm drawing, it can be challenging because not only do you need to know where the muscles are, but you also need to know how it changes as the arm twists and turns.

Fortunately, there are a number of tips to help you out. While the arm has a million types of muscles, we will start off by learning the important muscles that we can see.

As for the functions of the muscles, it functions in pairs. Flexor muscles pull in while extensors pull out. Obviously, the arm has several of these types of muscles around the joint regions. Knowing this is a great help to drawing the contractive nature of the arm muscles.

This lesson will allow you to making good judgment calls by introducing flow points to help you fill in where the major muscles are.

Let’s get started!

1. The front muscle groups

The diagram that I have drawn here is accurate to represent the length of the arm. Measured by the amount of heads, pay close attention to where all the major joint regions are located at. This will guide you where to start placing the muscles.

Your male arm drawing should contain the majority of the muscle groups listed here: the deltoid; triceps long head; biceps; triceps outer head; triceps inner head; brachialis anticus; pronator teres; brachioradialis; flexor carpi radialis; palmaris longus; and the flexor carpi ulnaris.

While it sounds like a lot to learn, you can group them up into easier bits. For example, the muscles groups of the triceps can be grouped into one area.

Other than that, learn these muscle groups and its positions on the arm as well as you can. This is the first step in making sure that you will have a good foundation for drawing and painting believable arms on your characters.

2. The back muscle groups

This particular male arm drawing is a diagram that shows all the major muscle groups at the back of the arms.

The muscles currently listed are: the deltoid; triceps outer head; triceps long head; triceps tendon; brachioradialis; extensor carpi radialis; anconeus; extensor communis; extensor carpi ulnaris; flexor carpi ulnaris; and the extensor of the thumb.

Aside from grouping similar muscles together, what makes this a little bit easier to memorize is that some of the muscles from the front will wrap around to the back of the arm.

We are also introducing the triceps tendons in this diagram where the elbows will go. Knowing this particular region in important because it is a good flow point not only for the elbow joints, but for where the muscles will flow around to when the arm starts bending.

The other important bit is the groups of muscles on the upper forearm. These will have a huge tendency to compress during any bending movements and needs be taken will a great deal of care when drawing these muscle groups to ensure accuracy.

3. The arm flow points

Perhaps the most significant learning step in your male arm drawing, picking out the flow points will allow you to understand the optimal method to ensure a high degree of accuracy.

Unlike the first two diagrams, this one will have the arm in a neutral position. That is, the muscles are not stressed at all to represent the most natural position of the arm.

From here, the arm can be split into three rotation points: shoulders, elbows, and the wrists. As the muscles move from the shoulders to the elbows, it actually rotates itself 45 degrees inwards. From the elbow to the wrists, it rotates 45 degrees inwards again.

Do not forget about specific landmarks of the arm such as the triceps tendon around the elbow region to help you accurately draw the arm in this neutral position.

Armed with this knowledge, it should greatly enhance your ability to visualize where all the muscle groups will fall into rather than just guessing.

Along with the muscle groups, once you memorized where the flow points, it is time to apply what you know into drawing the arm.

4. Drawing arm bends

By now, you should be very familiar with how the arm works and can visualize the major muscle groups in your head with minimal physical references.

In this exercise, you will see just how important those flow points are by drawing a bent arm. With your digital art tools, start illustrating a quick gesture/contour sketch of the arm in a ‘V’ manner.

Concentrate on flow points to allow you to sketch in quick chunks of muscle. Flex the biceps as the arm compresses itself. Note the triceps tendon area and the elbow. You want to make sure it sticks out as the muscles flow around it.

Depending on the position of the wrists and hands, angle your flow points from the elbow to meet it. Always make sure that the flow points suggest a rotation of the muscles in each of the three major joint areas.

Then, use your digital brushes to add some depth. Do not forget about the muscle groups in the upper forearm as the compression of these muscles will need a lot of details.

Use your smudge tool to get nice shading effects around the entire arm from the flow points. Also, do not forget about the bones in the wrist. While it is hard to see, it helps with the overall effect of creating an accurate arm.

With a little bit of practice, these tips will make a male arm drawing manageable and enjoyable! Have fun experimenting and learning!
