Olivia Munn already looked fantastic prior to joining “X Men Apocalypse”. However, the actress needed to get into shape for her role as Psylocke. As a result, she ended up looking better than ever.

Getting a Psylocke-like body is actually within reach. Munn didn’t go on any drastic weight loss program. She was smart and opted for a nutritious diet and hearty fitness regimen, E! Online reported.

For skeptics who want more proof that it works, supermodel Gisele Bundchen and her husband sportsman Tom Brady adhere to the same diet and fitness routine, the publication added.

Munn admitted her original goal wasn’t to lose weight. She wanted to be healthier. Her initial preparation for “X Men Apocalypse” involved regular personal training plus healthy eating. She eventually adopted the “20-80” diet, Mail Online revealed.

She ate fruits and vegetables 80% of the time and the rest of the time, Munn ate whatever she wanted. Her daily fitness routines throughout production that included sword training also helped her lose 12 pounds, the publication noted.

Olivia Munn is the June cover star of Women’s Health magazine that featured her amazing physical transformation.

“By the time I was finished [filming], I was 12 pounds less than I started…It’s a big difference because I started working out every single day, and then I also started getting into eating 20-80, where 80 percent of your diet is fruits and vegetables and 20 percent is whatever,” Munn revealed.

The actress also said she preferred getting into shape by way of martial arts rather than going to the gym. As it turns out, Munn has a black belt in taekwondo.

Olivia Munn also shared the physical sacrifices that came with hard training especially since she refused to use a stunt double on “X Men Apocalypse”. Her physical trainer Karine Lemieux revealed Munn’s discipline with food and training was essential to her transformation.

“She tried to eat as many fruits and veggies as possible…She just wanted to put everything on her side. She was already disciplined for that as well. If she wasn’t shooting, she was at the gym. No question,” Lemieux told Elle.
