It looks like this kitty is working out. Maybe this cat is teaching a class. This could be a world where cats talk. Or maybe you could just ignore the people in the picture and write about the cat. Or perhaps one of those ladies took the cat to class with them and the cat was just copying what they were doing. The kitty doesn't look very happy about doing this which I'm sure many of us can relate to since exercising sucks but it is a necessary evil. Now go forth and write.
Sometimes a picture can give you an idea. I'll post pictures here along with an idea. Use together or separately.
