Hi,
I've got a few workouts scribbled on paper, but want to give them away. So, i need to change my stick men to something more readable. My question is, does anyone know of a image base where i can find (preferably royalty free) drawings like these:

That i can use to put my own programme together? Any tips helpful.
Thanks!
