Hollywood actress Sydney Sweeney is a firm believer in going all in for her work. The actress built a gym in her house just to prepare for Christy. The 28-year-old actress plays boxer Christy Martin in the movie and she was “excited” to totally transform herself for the role, reports ‘Female First UK’. She told Britain’s OK! magazine, “I was excited to do it. I wanted desperately to do Christy justice and to make her proud”.

She further mentioned, “I really love to play characters that I can disappear into and just totally transform. I threw myself into every aspect of this character. I built a gym in my house. I had a professional boxing trainer, a weight trainer and a nutritionist. I was working hard every day to get where I needed to be physically”. As per ‘Female First UK’, the Euphoria star gained 35lbs for the role and admitted she often felt “so sick” as a result of her attempts to put on the pounds.
