Rosa Acosta has really been putting in a lot of effort into spreading awareness on health and exercise.  She's been working hard filming various workout videos where she showcases various forms of cardiovascular and general strength and conditioning exercises.  Most recently, Rosa also displayed her more limber side when she decided to give a little sneak peek at what fans can expect to see from her quality workout videos.

Rosa posed for the camera in an extremely flexible back bridge pose, which is something that you might find people doing only in an advanced Yoga class.  She managed to curve her back so much, that she dubbed herself "Miss Pretzel" in the photo.  Rosa has also uploaded tons of other workout images to her Instagram, showcasing her toned curves in various angles.
