Like plenty of ultra-fit guys, Crews loves to track his metrics, especially when he’s on set. And when he is filming, he usually burns a ton of calories, he says. “What’s so crazy, I found, in a day, I burn 7,000 calories,” he says. “It blew my mind.”

Whoop’s latest band offers a low-profile way to keep up that tracking. And Crews can’t help loving that, especially when he thinks back to how little data he had at the start of his career. “I’m from an era where we didn’t have a lot of monitors,” he says.

Problem solved.
