The actress, who will star in the action movie set in the 1950s, has admitted that the workouts were gruelling and painful.
Speaking to People, Hudgens said: "I trained with Navy Seals for five months. It was the most intense thing that anyone could ever do.
"I walk around with the biggest guns you have ever seen. I was bawling my eyes out because they push you so hard.
"But it’s amazing what you find from it. When you go so far you find a certain Zen within that and you know you can do anything. It’s very empowering."
Hudgens can next be seen in the fantasy drama Beastly, which arrives in US cinemas on July 30 and in the UK on October 15.
