The biggest hurdle to losing weight was cardio training, Army officials said in a news release.
Pinto began to combine jogging and sprinting to improve his times.
"Running wasn't my strong suit," Pinto said in the news release. "Carrying all that extra weight and trying to run definitely increased my time."
"When no one was looking, I was doing push-ups in my room, eating right, knowing what to eat," Pinto told KTNV. "I feel like everyone has the power to know what they take into their body, so I just took that into consideration. I just did the right thing at the end of the day,"
Pinto's work ethic impressed his friends, family and his Army recruiter, Staff Sgt. Philip Long.
"There were a couple times where he hit a plateau. He would lose a pound or two, maybe," Long told KTNV. "But to continue to push forward and put the effort and dedication in, it inspires me and it should inspire you."
Pinto will report to basic training in September, Army Times reported.
