Draw an Exercising Figure: Joint Bends and Motion Poses

Object Drawing Lessons

This lesson teaches you to draw an exercising figure by treating joint bends as measurable angles. You will study three reference poses (squat, overhead stretch, and bent-over lift), label hip, knee, shoulder, and elbow angles, and then compose an original exercise pose in a blank frame. The convention is simple: measure every joint angle between the two limb segments that meet at that joint, using the joint as the vertex. A straight limb is 180 degrees; a right-angle bend is 90 degrees. Because bodies vary, your drawn angles need only fall within the ranges given, and you may mirror the pose or adjust limb lengths proportionally. All angles below are hypothetical teaching examples, not measurements of any real person or equipment.

Set the angle convention before you draw

Place the joint as the vertex and measure between the two segments leaving it. For a knee, the segments are thigh and shin; for a hip, torso line and thigh; for a shoulder, torso line and upper arm; for an elbow, upper arm and forearm. Record angles in degrees and keep one unit system throughout.

Draw a faint stick figure first, then thicken limbs into simple tubes. Mark each joint with a small dot and write the angle beside it. This makes your drawing checkable with a protractor or by eye against the stated ranges.

1. Draw a vertical midline for the torso and mark hip, shoulder, and head centers.
2. Add limb segments as straight lines meeting at joint dots.
3. Label each joint angle at its vertex.
4. Convert the stick figure into simple body shapes without changing joint positions.

Squat pose: hip and knee bends

In a hypothetical squat reference, the hip angle is about 100 degrees and the knee angle about 90 degrees, with the torso leaning forward roughly 20 degrees from vertical. The arms extend forward at shoulder height, giving a shoulder angle near 90 degrees and elbows almost straight at 170 degrees.

Keep both knees bent by similar amounts so the figure reads as balanced. The feet stay flat and roughly shoulder-width apart; you may show them as simple wedges.

1. Mark the hip joint and draw the thigh downward-forward at the chosen hip angle.
2. From the knee dot, draw the shin back toward the foot at the chosen knee angle.
3. Lean the torso line forward and attach forward-reaching arms.
4. Check that the two knee angles differ by no more than 10 degrees.

Overhead stretch: shoulder and elbow extension

For an overhead stretch, both arms rise above the head. A hypothetical shoulder angle of 170 degrees (nearly straight up from the torso line) and elbow angles of 175 degrees produce a long reach. One hand may overlap the other, but keep both shoulder angles within 10 degrees of each other.

The torso stays vertical and the legs are nearly straight, with hip and knee angles around 175 degrees. Slight asymmetry is acceptable if you note it.

1. Draw the vertical torso and mark both shoulder dots.
2. Extend upper arms upward at the chosen shoulder angle.
3. Add forearms at the chosen elbow angle, letting hands meet or nearly meet.
4. Verify leg angles are close to straight and label them.

Bent-over lift: hip hinge with bent knees

A hypothetical lift pose uses a hip angle near 60 degrees (a deep hinge), knee angle near 120 degrees, and shoulder angle near 90 degrees with elbows at 160 degrees so the hands hang below the shoulders. The back line stays long and straight from hip to head.

This pose combines a large hip bend with a moderate knee bend, which is the key contrast to the squat. Label both angles so the difference is visible.

1. Draw the torso hinged forward from the hip dot.
2. Bend the knees moderately and keep feet flat.
3. Let arms hang toward the floor with slight elbow bend.
4. Check that the hip angle is smaller than the knee angle, matching the hinge pattern.

Worked example

A figure stands with the torso vertical. The right hip angle is 150 degrees, the right knee angle is 130 degrees, the right shoulder angle is 45 degrees, and the right elbow angle is 90 degrees. Describe the pose and state whether the knee bend is deeper or shallower than a right angle.

Four practice exercises

Common mistakes

• Measuring the joint angle from the vertical instead of between the two limb segments. Place the protractor vertex on the joint dot and read between the two segments that meet there.
• Drawing both knees at very different bends in a symmetric squat. Compare the two labeled knee angles and adjust until they differ by 10 degrees or less.
• Letting the torso line bend at the waist in the lift pose. Keep one straight line from hip dot to head center and hinge only at the hip joint.
• Labeling angles without units or mixing degrees and arbitrary units. Write every angle in degrees and keep the same convention across all labels.

Self-check rubric

• At least three joint angles are labeled in degrees at the correct vertices.
• Each labeled angle matches the drawn limb segments within about 10 degrees by eye or protractor.
• The pose is an exercise motion and is not running, walking, or seated.
• Symmetric poses keep paired joint angles within 10 degrees of each other, or asymmetry is noted.
• The torso line is straight in the lift pose and hinges only at the hip.
• Valid alternatives such as mirroring or proportional limb changes are accepted if angles stay in range.
