Thats what I was looking for to read. Maybe it isnt a witch. Maybe it is some kind of demon like the ones in those Hellraiser movies. They use working out or weight loss as a form of punishment. The victims end up anorexic and and malnourished. https://youtu.be/iPUwtyZglQI
Any horror books related to witches from Hell that force people to work out?
