This lecture demonstrates the structure and anatomy of the human arm. In a continuation of his previous lectures on human anatomy, figure artist Charles Hu begins this lecture with a review of the primary skeletal structures of the arm. After discussing the primary structures and proportions, Charles begins by breaking down the primary muscle groups. Starting with the shoulder and upper arm, he works his way down to the forearm's muscle groups, explaining supination and pronation while also discussing the muscle connections and their action. In the last four chapters, Charles works from different examples of photo reference, identifying key structural landmarks while also deconstructing the contributions of anatomy, gesture and rhythm to the motion of the underlying skeletal structure. The mechanical and structural understanding that Charles shares in this title is an essential foundation for producing believable and dynamic figure drawings, either from life or from the imagination.

01Overview of the Arm skeletal systemFree

This workshop by Charles Hu provides essential anatomical knowledge for figurative artists who need to accurately draw arms in various positions and gestures. Understanding skeletal architecture, joint articulation, and rotation mechanics is fundamental before adding muscles. Charles emphasizes that knowing which parts of the arms remain fixed versus which rotate is critical for maintaining anatomical accuracy regardless of the pose.

Duration: 26m 37s

Overview of the Arm skeletal system
02Muscle of upper arm

This lesson breaks down both the scientific understanding and artistic application of upper arm musculature. Charles successfully bridges anatomical knowledge with practical drawing principles, highlighting how asymmetrical muscle arrangement creates natural rhythm and visual appeal. Artists learn how muscles function and interact to create accurate and natural-looking artwork.

03Shoulder structure and Anatomy

Charles emphasizes using specific anatomical landmarks as reference points for proportions and spatial relationships while applying artistic principles like line weight variation and shadow placement. By combining anatomical knowledge with drawing technique, artists can avoid common mistakes such as flattened chests or disconnected muscle groups.

04Muscle of Triceps and Flexor group

Charles Hu explains the relationship between muscle structure and surface form, which is particularly important for artists and sculptors. Understanding the origin, insertion, and function of arm muscles helps create accurate, dynamic representations of the human body. Charles breaks down anatomical structures into memorable patterns and visual relationships for rendering the arm in various positions.

05Muscle of Out side view of the arm

Understanding the structural geometry and directional flow of the arm is prioritized over memorizing individual muscle names. Charles shows how the upper arm, forearm, and hand form an alternating pattern of directional planes that interlock like puzzle pieces. Artists learn to recognize anatomical parts and muscle origins to create more accurate and dynamically connected figure drawings.

06Muscle of the thumb and Structure of hand

This lesson demonstrates that understanding thumb and hand musculature leads to more accurate artistic representation. Charles shows how recognizing tendons creates visible surface forms and connections from the forearm to the fingers. Artists explore how foundational knowledge of underlying anatomical structures leads to better proportions and a more natural flow.

07Demonstration from Photo – Part 1

While understanding muscle structure is essential, Charles highlights that artists must make deliberate choices about line weight and shadow placement to create compelling, three-dimensional forms. Using anatomical knowledge as a foundation while applying design principles creates visual interest and depth that effectively guides the viewer's eye.

08Demonstration from Photo – Part 2

In this lesson, Charles makes it a priority for artists to analyze how muscles interact and where tension occurs to create dynamic, three-dimensional forms. Maintaining gesture and flow throughout the drawing ensures the figure feels unified and alive.

09Demonstration from Photo – Part 3

Understanding anatomy as a foundation for artistic interpretation and design is crucial for artists to create believable figure drawings. Charles advocates moving beyond abstract lines to incorporate structural knowledge that communicates weight, action, and purpose. By studying how muscles overlap and attach to bones, artists learn to make informed decisions that serve a drawing's narrative.

10Demonstration from Photo – Part 4 and Final thought

This final lesson emphasizes that successful figure drawing comes from understanding the relationships between forms. While anatomical knowledge provides essential tools, Charles shows that the real skill lies in designing elements to work together organically to create rhythm and energy. Artists learn through dedicated practice to experiment boldly and push boundaries.

Skills Covered

Who’s this Workshop for?

This workshop is designed for intermediate to advanced figure artists, illustrators, and concept artists who want to take their anatomical understanding to the next level. Artists with basic drawing skills who are ready to tackle more complex structural concepts will gain tremendous value from Charles Hu's instruction.


Character designers, comic artists, and fine artists working in figurative styles will also benefit greatly from this approach. The training builds essential skills for creating believable, dynamic figure work, whether drawing from observation or imagination.

Learning Outcomes

Artists will leave this workshop having developed a comprehensive understanding of arm anatomy and its application to dynamic figure drawing.


Key skills include:

  • How to identify and accurately draw the primary skeletal structures of the human arm.
  • How to understand proper proportions and relationships between shoulder, upper arm, and forearm segments.
  • How to analyze and render the major muscle groups from shoulder to hand.
  • How to demonstrate supination and pronation movements and their anatomical implications in drawings.
  • How to identify key structural landmarks using photographic reference for accurate figure construction.
  • How to integrate anatomical knowledge with gesture and rhythm for dynamic figure compositions.
  • How to apply mechanical understanding to create believable arm positions from imagination.
