Ginés started climbing with his parents when he was very young. In 2013, Ginés, who was 10 years old at the time, met professional climbing coach David Macià in Rodellar, after his father introduced the child to him. Macià was surprised by the attitude with which Ginés climbed El Delfín (7c+), and became his coach. In 2016, after the announcement that climbing would become an Olympic sport at 2020 Summer Olympics in Tokyo, he moved from Cáceres to Barcelona to train, with the goal of qualifying for the international event.[3]
