Body acceptance has come a long way since the Shallow Hal era, but there’s still a lot of work to be done. Last week, The Daily Mail published photos of Sydney Sweeney showing off her “incredible bikini body” at her Florida home.

Sydney Sweeney hit back at body shamers who frequent her social media accounts Friday with video that showed her training regimen from her upcoming Christy Martin biopic. The clip, shared on Instagram, started with a series of insulting and sexist social media about her body followed by footage of her training in the gym for the role.
