Alexandra Shipp’s work out ahead of #XMen filming.

Alexandra Shipp is working on her fitness before next month’s production start on X-MEN: APOCALYPSE. The younger “Storm” actress posted a photo from her workout, saying “For this ex-chubby AZ girl to get into shape… I must avoid my nemesis Mexican food.”

Celebrity fitness guru Holly Lawson posted video of Shipp’s tredmill run. “I love my clients,” she says. “It makes work nothing close to actual “work”! I couldn’t be more proud of Alex and the work she’s putting in. 6-pack and biceps on fleek! (A lot of which is due to me cleaning up her nutrition and that lack of Mexican food she’s speaking of).”

For this ex-chubby AZ girl to get into shape… I must avoid my nemesis Mexican food… Thanks for the great workout @lilbearlawson #TeamLilBear
