Please note the color preferences on the contest discussion. Your concept is a top pick. We are unsure if we'll go with a "B" as the icon but really like the white standing out.
It may be difficult to demonstrate in a logo, but showing someone getting results, progressing, making a transformation over time would best describe our brand or what we do. I'm not sure if this is a person with extra room in his/her jeans (not gender specific) - or something non traditional and creative that shows "getting results." If you can communicate the emotion of having fitness success, then we'd like to see your concepts.
