James Brolin looks way younger than his age, thanks to these secrets.

Fans surely cannot believe that Brolin is now 82 years old as the actor remains in great shape compared to others of the same age. For those who have been curious about his secret, the "Catch Me If You Can" star finally unveiled his regime in an exclusive interview with PEOPLE.

During a lunch with the news outlet near his Malibu home, the actor recalled his meeting with surfer Laird Hamilton - who taught him the unusual water workouts that helped him to be in great shape.

According to the "Lightyear" voice actor, he met Hamilton and Gabby Reese during a party of his friend. At that time, Brolin was already feeling down about his appearance and body. Thus, he was already aiming to change his fitness routine and diet.

"Laird said, 'Why don't you come on up to the pool and work out with us on Tuesday, Thursday and Saturday?' So I went, 'Yeah, okay, great.' I didn't," he said.

But one day, Brolin reportedly changed his mind and tried the regime. From there, he started doing the workout routines regularly and even took it to the next level by using weights.

Although he found it hard at first to the point that he almost gave up, the actor trusted Laird and the unique aquatic plan.

After going through it, the "Capricorn One" actor noticed his massive transformation inside and out. That explains why he began to look better and younger again.

On top of the workout, he also gets rid of extra fats in his body by staying in the sauna at his home for 40 minutes, three times a week.
