Actress Ruby Rose, who is getting ready to play lesbian Batwoman in a new series, showed off her martial arts skills on Instagram. On Saturday, Rose gave a sneak-peak at her martial arts training, which is likely to be part of her preparations for the iconic role, reports a website. The model-turned-actress looked to be in serious Zen mode as she followed her instructor’s every move and instruction. She is dressed in full martial arts garb that included a robe, matching pants and a black cloth tied around her lean waist. Initially, the instructor had her working on her arm and wrist strength by slowly lifting a piece of concrete with a stick and rope. The instructor then went into a number of held positions which Rose captioned: “This part I can do.” Eventually the training turned to some relaxed maneuver that involved breaking a piece of metal in half by slamming it into his arms. With this the actress wrote: “This part I can not do… yet.” (IANS)
