I spent some time this evening trying to create some simple pictures that trainers can use in class when the need comes by. You can see above the result of the exercise. This didnt take me much time and while I know that the above set doesnt represent a complete toolkit in anyway, I found that making this brought out the child in me. I hope even practicing such simple sketches will help some of my fellow trainers feel more competent when drawing to teach.
Disclaimer: I havent labelled the pictures in the belief that "a picture speaks a thousand words"; though this could be a result of my undeserved faith in my own artistic ability (or the lack of it).
