Jewelry's former member Jo Harang showed off her fit body through a series of photo uploads on Twitter, which accompanied her admission of wanting to write a fitness book. On February 10th, the singer tweeted, "Harang goes to two gyms.  I've visited this gym for the past three years, and recently visited again after a long while. Whose bulky arm do you think this is?" Fans took the nail art to be a hint that it was her and answered accordingly. "Ding dong dang! You are right," she tweeted back. Jo continued her series of tweets by giving some workout tips. "Since I'm a girl, I don't add heavy weights, and instead work out quickly and accurately with three sets of 15. Muscles that are bigger, like your back, I divide into three sections and focus on each part individually." She also tweeted another photo, "Cheerleader Jo Harang." When one netizen suggested that she release a book titled "How to Create an Ant Waist by Jo Harang", she replied, "I'll release one within a few years.  Even if it isn't right away." Fans commented, "I never knew Jo Harang's body was this great", "A luxurious body created out of exercise", and "You're so pretty and slim, please tell us your secret." Source: Star News via Nate
