It's only been a day since she it was confirmed that she will be playing Darna for an upcoming film about the Pinay superhero. But Liza Soberano is already hard at work to get into shape for the part.

An Instagram snap from celebrity fitness instructor Bok Santos, who also trains the likes of Erich Gonzales, shows Soberano working up a sweat in a gym as she did some push-ups early Wednesday.

In an interview with ABS-CBN News' MJ Felipe, Soberano said she will undergo intensive physical training, as well as attending acting and dialogue workshops, in preparation for the "Darna" movie.

"I want to look physically strong," she said, adding that she would like to do her own stunts.

Another post from Santos revealed that he will be overseeing Soberano's training.

A release date for the "Darna" movie, which will be produced by Star Cinema and directed by Erik Matti, has yet to be released. Angel Locsin was first slated to lead the movie but had to back out because of a spine injury.
