Step 15: Follow the basic path of the original rectangle to create the shape of the face. Make the bottom part rounder as you follow the guide. Inside the face, draw a u-shaped line for Muscle Man's chin.
Step 16: Use the angled line on the right as a guide to draw the arm. Follow the basic path of the guide as you make the shape of the arm thicker. Draw Muscle Man's hand within the shape of the circle using a series of curved lines.
Step 17: Draw the arm on the left the same way. Follow the path of the guide as you make the shape of the arm thicker. Use curved lines inside the small circle to create Muscle Man's small hands.
Step 18: Use two curved lines for Muscle Man's chest. The curved lines should be placed just above the hands. Draw a long, curved line below the hands for the bottom of the shirt. Add a tiny, curved line near the middle for Muscle Man's navel.
Step 19: Draw another long, curved line under Muscle Man's shirt for the top of the pants. Use the lines at the bottom as guides to draw shape of the legs. Follow the basic path of the guides as you make the shapes of the legs thicker.
