Boy group BEAST's member Yang Yoseob revealed a picture taken while working out.

Today, Yang Yoseob posted on his Twitter, "I'm not crying because working out is hard, I'm crying because I'm touched" along with a picture.

In the picture, Yang Yoseob is wearing a sleeveless tee and is sitting in front of the mirror at the gym. One of his hands is covering his face. His small face that fits into his whole hand and his buff arms are eye-catching.
