Drawing the human back is a challenging task, but with practice, anyone can master it. The first step is to learn basic anatomy, including the bones and muscles of the back. The main muscles of the back can be grouped together, making it easier to memorise their locations and relationships. The scapula, or shoulder blade, is the most important for constructing the back. It is triangular in shape and is most visible on people with less developed upper back muscles. The next step is to identify landmarks to keep your drawing accurate.

What You'll Learn
Basic anatomy
The human body has more than 600 muscles, which are attached to the bones of the skeletal system. These muscles are responsible for movement, posture, and balance. They also move and support the organs. The muscular system can be divided into three types of muscle tissue: visceral, cardiac, and skeletal.
Visceral muscle is a type of involuntary muscle that lines some of our organs. It is controlled by the unconscious part of the brain and cannot be consciously controlled. This is the weakest type of muscle tissue. Visceral muscle is found in organs like the stomach, intestines, and blood vessels.
Cardiac muscle is only found in the heart, where it is responsible for pumping blood throughout the body. It is also an involuntary muscle, contracting to stimulate the heart.
Skeletal muscles are attached to the bones by tendons and are under voluntary control. They are responsible for movement, such as running, as well as holding the body still. They are also grouped by their location, such as chest, leg, or back muscles. Examples of skeletal muscles include the trapezius, which extends across the upper back, and the pectorals, which are found behind the mammary glands in the female body.
The neck, or cervical spine, is an important area of movement. The sternocleidomastoid muscle, which is visible due to its V shape, is responsible for rotating the neck and assisting in forced inhalation. The cervical spine also allows for side bending, which is facilitated by the splenius capitis and splenius cervicis muscles.

Bones and muscles
When drawing the human back, it's important to have a basic understanding of the underlying bones and muscles. The main bones of the back are the scapula (or shoulder blade) and the rib cage. The scapula is triangular in shape and moves and rotates around on top of the rib cage. During certain movements, such as pulling actions or when the arm is raised or pulled back, the scapula may be more visible as it pushes against the muscles. The degree of visibility also depends on the build of the person you are drawing—for example, the scapula is more visible on individuals with less developed upper back muscles.
There are several large muscle groups in the back, including the latts (Latissimus Dorsi), the Trapezius, the Teres group, and the obliques. The latts form a cape-like shape in the lower back region, while the Trapezius is visible from the front but has most of its mass hidden in the back. The Teres group works with the Trapezius and the shoulder blade to help move the arms, and the obliques wrap around from the sides of the torso to meet the latts.
When drawing the back, it can be helpful to first sketch the muscle groups over a basic stick-figure-like frame before adding more detail to the figure. This can aid in understanding the complex interplay between the bones and muscles of the back. Additionally, using symbols to represent different muscle groups can be a useful memorisation technique. For example, the arrowhead symbol can represent the deltoid muscle due to its similar shape, while the wishbone symbol can combine multiple muscle groups.

Landmarks
When drawing the human back, it is important to know the basic anatomy, including the bones and muscles. The scapula, or shoulder blade, is the most important structure for constructing the back. It is triangular in shape and is most visible on people with less developed upper back muscles, especially during pulling movements. The upper and inner sides of the scapula are usually the most visible parts. The spine of the scapula, to which the trapezius muscle attaches, is a key landmark. The rear deltoid attaches to the other side of the spine of the scapula.
The back can be divided into three main structures: the back of the rib cage, the scapula, and the shoulder blade, which together form the upper back. The scapula moves and rotates around on top of the rib cage, and there are many muscles covering it. Depending on the movement and the build of the person, more bone or muscle will be visible. The scapula can be covered by muscles or stand out, especially when the arm is pulled back, changing the visible shapes. The inner portions of the scapula, closest to the spine, often stand out in less muscular figures.
The main muscle groups of the back include the latts or Latissimus Dorsi, which form a cape-like shape in the lower back region. The Trapezius, or "traps", are visible from the front but have more mass hidden in the back. The Teres group is a smaller section that works with the traps and the shoulder blade to move the arms. The deltoid connects on top of the Teres group, and the obliques wrap around from the sides of the torso to meet the latts.
To visualise the torso in 3D space, an exercise is to draw boxes showing the backside and practising how the spine connects at the pelvis. Using symbols is also a helpful way to memorise the shapes and connections of the muscles. For example, the arrowhead symbol represents the deltoid's shape and connection, while the wishbone symbol combines multiple muscle groups.

Muscle groups
The human body has over 650 distinct muscles, but you don't need to memorise all of them to design an effective workout routine. Fitness experts categorise these muscles into 11 major muscle groups to make things simpler. These are: glutes, back, chest, shoulders, quadriceps, hamstrings, calves, triceps, biceps, abs, and grip and forearms.
These muscle groups can be further simplified into four categories: upper body, lower body, core, and legs. A workout split is a common strategy used to address all these muscle groups in a training plan. This involves splitting up workouts on different days to focus on different muscle groups and increase training intensity. For example, a three-day workout split could consist of chest, shoulders, and arms on day one; legs, abdominals, and back on day two; and arms, shoulders, and core on day three.
The core muscles are central to the body and include the abdominals, obliques, lower back, and glutes. They are connected to all the other muscles and provide stability and spinal support. A strong core promotes good posture and assists in various body movements such as walking, running, bending, and twisting. Examples of core-strengthening exercises include yoga, pilates, planks, and crunches.
The gluteus maximus is the single largest muscle in the human body and is important for athletic performance. It, along with the gluteus medius and gluteus minimus, originates from the pelvis and inserts into the femur.

Proportions
Proportion is key when drawing the human back. The first step is to get to grips with the basic anatomy of the back, including the bones and muscles. The skeleton forms the foundation of the torso's anatomy. The back can be divided into three main structures: the back of the rib cage, the shoulder blade, and the scapula or shoulder blade in relation to the musculature. The scapula is triangular in shape and is most visible on people with less developed upper back muscles, particularly during pulling movements. The upper and inner sides of the scapula are usually the most visible parts.
The next step is to identify the main muscle groups of the back and memorise their locations and relationships. The biggest muscle group is the latts or the Latissimus Dorsi, which forms a cape-like shape in the lower back region. The Trapezius is another muscle group, visible from the front, but with most of its mass hidden from view at the back. The Teres group is a smaller section that works with the traps and the shoulder blade to help move the arms. The obliques wrap around from the sides of the torso to meet the latts.
When drawing the back, it is useful to draw the muscle groups over the reference before drawing the total figure. This can help you to visualise the torso shapes in 3D space. You can also use symbols to help memorise the different muscle groups. For example, the arrowhead symbol translates to the actual shape of the deltoid, and the wishbone symbol combines a few muscle groups together.
Finally, check your proportions. It is recommended that you do not measure these as you draw, but instead practice using your artistic eye to judge the distance and then double-check afterward.
