Keri said that a “tough bike ride” is her go-to. “Or I’ll dance around in my room to loud music and do moves I remember from a pregnancy video I had,” she said.

Biking helps Keri’s mental health, too, she told the Las Vegas Review-Journal in 2023. “To get rid of stress, I ride my bike into the city from my home in Brooklyn and over the bridge into Manhattan,” she said. “I’ll do it at 5:30 in the morning when the city is quiet.”

When she was shooting The Diplomat, Keri said that she “rode a bike all over London, which was wonderful. You get exercise and really see the city.”

She hits the gym occasionally.

Keri has a busy schedule, juggling a demanding career and being a mom. (Keri shares children River and Willa with ex-husband Shane Deary and son Sam with partner Matthew Rhys.) Still, she hits up the gym when she can.

“If I have a good chunk of time, I’ll go to a gym and do exercises using a band that a trainer taught me 20 years ago,” she told Shape.

She trains for roles like ‘The Americans.’

Keri has a lot of physically demanding roles, and she trains hard for them. Keri learned Krav Maga, a military self-defense and fighting system developed for the Israel Defense Forces, to play a secret agent in The Americans.

“Working out this way makes you feel fierce,” she told Shape (via Prevention). “I tend to be internal—getting on the subway and keeping my eyes down. But I would leave those workouts looking people in the eye like, ‘sup?'”
