People Editorial Guidelines Published on April 5, 2021 03:15 PM Share Tweet Pin Email Terry Crews is reflecting on the ways in which he was shaped by his troubled childhood. While exploring the Icelandic Highlands on Monday's episode of Running Wild with Bear Grylls, Crews opens up about his focus on health and fitness — and the painful origin story behind it. "After my time in the NFL, one thing I noticed is that if you make everything sports-specific, all of sudden, when the sport is over, guys just waste away," the America's Got Talent host, 52, tells Bear Grylls in PEOPLE's exclusive sneak peek. "You've got to understand, there was a time in my life where I got overweight because I was depressed. I'm depressed, I need something, I need a change, I need to go to the gym 21 days straight. That 21-day period turned into 21 years." "I was naturally just wanting more," he continues. "You've got to know, growing up [for me] was not a good experience. My father was very abusive. He used to beat my mother. So it was one of those things where I knew I had to get stronger because one day I thought I'd have to fight him. That's how it started out." Crews says this thought process began when he was just 5 years old. "I always, always had been like, 'Be fit, be ready, be prepared, be there,'" he recalls. "But even then it's hard, because certain things did trip me up that I had to get over."

Paula Lobo/Walt Disney Television via Getty Crews has previously spoken about his complicated relationship with his father, Terry Crews Sr. In 2014, the Everybody Hates Chris alum wrote an essay for HuffPost about how he learned to forgive his dad. "I started giving Big Terry credit for what he did do. He was a good earner. He was a good provider," he wrote. "I never excused what had been wrong, but also being able to see the positive finally changed my perspective. It changed my view of our story. Finally, it all became clear to me, and I called my father." The actor has been married to Rebecca King-Crews since 1990. Last month, the couple spoke to PEOPLE about how they've worked through the ups and downs of their 32-year marriage, including his porn addiction struggles and her battle with breast cancer. "He's the hero of our story, in my opinion," said Rebecca, 55. "He made the choice to take this battle on and really become a better person."
