 Over time it has become clear to trainers and health professionals that the idea of working out certain muscle groups, in order to burn fat in that specific area, is not possible.Advertisements, magazines, internet trainers, and social media continue to push the idea that through exercising small isolated muscles, such as abdominal muscles, it will help the fat above the muscles disappear.Fitness professionals say this is false, yet, even trainers still use phrases like "burning fat", and targeting "troubled areas" like "muffin tops" to pull people in.
