Specific Remove people in background

[Edars]

Could somebody plz remove all of the people in the background so that it looks as if the person is benching alone?? Thanks.

Lots of improvements are further possible, but this would have to do for the time I can invest at the moment. If someone wants to take over and add the yellow triangles, that would make it a better result. There is also a little bit of skin left to cover beside the Right hand little finger too.
