Object Drawing Lessons
This guide teaches you to draw a seated barbell twist exercise pose using a simple convention: the torso rotates around a vertical axis while the hips stay square. You will place the seat, define the pelvis and ribcage as two stacked boxes, add the barbell across the shoulders, and show rotation with curved arrows. The method avoids general figure proportion rules and gym equipment construction; it focuses on the pose itself. All measurements are hypothetical examples you can adjust after measuring your own paper and reference. A practice box helps you compare your sketch against checkable landmarks.

Set the seat and pelvis landmarks
Begin with a light vertical midline for the spine and a horizontal line for the seat surface. Draw the seat as a simple side-view rectangle: for example, 6 cm wide and 2 cm tall on A4 paper. Place the pelvis as a shallow box centered on the seat, tilted slightly back so the sit bones rest on the seat. Mark the hip corners with two small dots; these stay fixed because the hips do not rotate in this pose.
Use a second horizontal line at the top of the pelvis box to separate pelvis from ribcage. Keep this line level even when the torso twists. Label the left and right hip dots so you can check later that they have not drifted.
- Draw a vertical midline and a horizontal seat line.
- Sketch the seat rectangle and mark its center.
- Place the pelvis box on the seat with two hip dots at the corners.
- Add a level line at the top of the pelvis box.
Stack the ribcage and show rotation
Draw the ribcage as a second box above the pelvis, narrower at the top. To show a twist to the left, shift the top corners of the ribcage box slightly left while keeping the bottom corners near the pelvis line. Add a curved arrow around the ribcage: start at the right side, curve forward and to the left, and end at the left side. A second smaller arrow at the waist reinforces the rotation direction.
The head follows the ribcage but stays upright. Place a small oval for the head above the ribcage, centered over the twisted upper box. Shoulders sit at the top corners of the ribcage; draw them as short horizontal segments that rotate with the ribcage, not with the hips.
- Sketch the ribcage box above the pelvis, narrower at the top.
- Shift the top corners left to indicate a left twist.
- Draw a curved rotation arrow around the ribcage.
- Add the head oval and shoulder segments aligned with the ribcage.
Place the barbell and limbs
The barbell rests across the shoulders behind the neck. Draw it as a long line with small circles at each end for plates. For a left twist, the left end of the barbell moves slightly forward and the right end slightly back; show this with a shallow diagonal. Because the bar is angled in depth, draw its midpoint at shoulder height and let the ends sit at slightly different heights, with the end circles just outside the hands.
Arms bend at the elbows with hands gripping the bar just outside the shoulders. Draw upper arms as short lines from shoulder to elbow, then forearms to the hands. Feet rest flat on the floor in front of the seat; draw simple foot shapes with toes pointing forward. Keep knees apart and lower legs vertical.
- Draw the barbell line across the shoulders with end circles.
- Angle the barbell slightly to match the twist, keeping its midpoint at shoulder height.
- Add upper arms, forearms, and hands gripping the bar.
- Draw feet flat on the floor with toes forward.
Use the practice box and rotation arrows
Create a practice box beside your sketch: a 5 cm by 5 cm square divided into four smaller squares. In the top-left square, draw a mini version of the pelvis and ribcage boxes. In the top-right, draw only the rotation arrow. In the bottom-left, draw the barbell angle. In the bottom-right, draw the foot placement. This box lets you check each element separately before combining them.
Compare your main sketch to the practice box: hip dots should align with the seat center, the ribcage top should shift in the arrow direction, and the barbell midpoint should sit at shoulder height with its ends angled to match the twist. Use a colored pencil to trace the rotation arrow so it stands out.
- Draw a 5 cm square and divide it into four equal squares.
- Fill each square with one pose element: boxes, arrow, barbell, feet.
- Compare the main sketch to the practice box.
- Trace the rotation arrow in color for clarity.
Worked example
Draw a seated barbell twist to the right on A4 paper using a 6 cm by 2 cm seat and a 5 cm practice box. Show the pelvis fixed, the ribcage shifted right, and the barbell angled.
Worked answer
Seat rectangle centered on the page; pelvis box with two hip dots on the seat line; ribcage box above with top corners shifted right; curved arrow from left to right around the ribcage; barbell midpoint at shoulder height with left end slightly back and right end slightly forward; hands gripping outside shoulders; feet flat with toes forward; practice box filled with four mini-elements matching the main sketch.
Four practice exercises
Exercise 1
On a 10 cm by 10 cm area, draw a seated barbell twist to the left. Use a seat 5 cm wide and 2 cm tall. Mark two hip dots and one rotation arrow. Describe where the ribcage top shifts.
Show answer and check
The ribcage top shifts left; hip dots stay on the seat line; the arrow curves from right to left around the ribcage.
Why: A left twist moves the upper torso left while the pelvis remains fixed, so the ribcage top must shift left and the arrow must show that direction.
Check: Measure that both hip dots lie on the seat line and that the ribcage top is left of the pelvis center; confirm the arrow starts on the right and ends on the left.
Exercise 2
Draw a seated barbell twist to the right in a 5 cm practice box divided into four squares. In square one draw pelvis and ribcage boxes; square two the arrow; square three the barbell; square four the feet. State the barbell angle.
Show answer and check
The barbell angles so the left end is slightly back and the right end slightly forward; the arrow curves left to right; feet are flat with toes forward.
Why: A right twist moves the right shoulder forward, so the barbell end on that side moves forward while the opposite end moves back.
Check: Check that the barbell midpoint sits at shoulder height, its ends angle with the twist, and the arrow direction matches the ribcage shift.
Exercise 3
Sketch a seated barbell twist to the left with the barbell drawn level. Then correct it by angling the barbell. Explain the correction in one sentence.
Show answer and check
The corrected barbell angles with the left end slightly forward and the right end slightly back, matching the left twist.
Why: A level barbell contradicts the torso rotation; angling it aligns the bar with the twisted shoulders.
Check: Compare the barbell angle to the rotation arrow: the forward end should be on the side the arrow moves toward.
Exercise 4
Draw a seated barbell twist to the right and include a head oval. Check that the head sits over the ribcage top, not the pelvis. If it sits over the pelvis, move it and state the new position.
Show answer and check
The head oval should be centered over the right-shifted ribcage top; if it was over the pelvis, move it right and up to the ribcage top.
Why: The head follows the ribcage during a twist, so its center must align with the twisted upper box.
Check: Draw a vertical line from the head center down; it should pass through the ribcage top, not the pelvis center.
Common mistakes
- Rotating the pelvis along with the ribcage. Keep the two hip dots fixed on the seat line; only the ribcage box shifts.
- Drawing the barbell level when the torso twists. Angle the barbell slightly so one end moves forward and the other back, matching the arrow direction, while keeping its midpoint at shoulder height.
- Placing the head outside the ribcage box. Center the head oval over the twisted top of the ribcage, not over the pelvis.
- Letting the feet lift or turn outward. Draw feet flat with toes forward and lower legs vertical; check against the practice box.
Self-check rubric
- Hip dots remain on the seat line and do not rotate.
- Ribcage top shifts in the direction of the rotation arrow.
- Rotation arrow curves around the ribcage and matches the twist direction.
- Barbell midpoint sits at shoulder height and its ends angle with the twist.
- Head oval sits over the twisted ribcage top.
- Feet are flat with toes forward and lower legs vertical.
- Practice box contains four distinct elements matching the main sketch.
- Valid alternatives: either twist direction is acceptable if consistent; seat size may vary after measuring paper; barbell length may vary if hands grip outside shoulders.
Questions and answers
Do I need to draw realistic muscles?
No. The convention uses simple boxes and lines. Focus on the rotation arrow, fixed hip dots, and barbell angle.
How do I know which way the torso twists?
Choose a direction and keep it consistent. A left twist shifts the ribcage top left and curves the arrow from right to left.
Can I change the seat size?
Yes. The 6 cm by 2 cm seat is a hypothetical example. Measure your paper and adjust while keeping the pelvis centered.
What if my barbell looks too long?
Shorten it so the end circles sit just outside the hands. Keep the barbell midpoint at shoulder height and angle the ends to match the twist.
