Idk how to either. I just draw a circle, a line for a neck, a square or thicc triangle for a body, and then a rectangle for a waist, and finally 4 more weird looking triangles for legs (2 for each leg)

I do a circle for the head, rectangular kind of shape for the torso and a triangle for the hips. Add circles at the top corners for the shoulders, the elbows reach the top of our hips, so draw a circle there, then join the shoulder circle and the elbow circle. Repeat on other side. Basically do the same things for the knees. From the hips to the feet is about the height of from the head to the bottom of the torso, split that length and you get the knee points.
