My upper abdominals are sticking out during a HS

Hi !

 

During a wall HS my upper abdominals ( the actual place where the stomach is located )

But I dont feel that it is sticking out ( usually I feel that my lower back is arched during a wall HS so i can correct it and so and so )

How big is the problem ?

 

Any ideas on how to fix it? 

Post a video, otherwise it's hard for people to make suggestions.
