4minute has released a BTS video on their website where you get to see the girls as they were shooting for their album jacket photos. Gayoon said while getting interviewed, "I've only been eating chicken breast. I have been exercising consistently and maintained a healthy diet with our dance practices." I always thought girl groups naturally had amazing bodies but it looks like everyone works hard for their bodies. http://www.youtube.com/watch?v=0K08b_UYdwo
