In the same Instagram post, Wilson says that she is an avid hiker, writing, "This week was super busy but I got up super early three times (6am) and went on a hike."

In an interview with Wilson's trainer, Jono Castano, he revealed that Wilson does a lot of HIIT workouts and circuits. "We focus on plenty of HIIT circuits, but at the same time, focusing on technique and tempo," he says. Castano says that the actress does HIIT workouts four times a week.

Castano broke down Wilson's fitness schedule to E! Australia, and the actress works out six days a week, with one rest period on day six. 

Castano tells E! Australia that he will vary Wilson's workouts, and that they focus on different aspects with each workout. He says, "Understanding that each exercise is vital when working at a quick capacity. Another element we focused on was resistance and mobility training to ensure we're covering all areas, including posture."
