Stephen Curry says one rule about when to 'quit' keeps his marriage strong

• Stephen Curry says a simple rule has helped shape the way he approaches his marriage.
• The NBA player says he believes that neither partner can check out at the same time.
• "We don't run away from the tension on the daily," Curry said.

Stephen Curry has spent almost 15 years building a marriage while navigating a demanding NBA career.

During a joint appearance with his wife Ayesha on Wednesday's episode of the "IMO" podcast. Curry said one simple mindset has helped them get through the hardest moments together.

"We don't run away from the tension on the daily," Curry told podcast hosts Michelle Obama and Craig Robinson. "Again, I think I heard somebody say like, neither one of us can quit on the same day, as a philosophy of understanding."

The NBA player said it all comes down to knowing your partner well enough to recognize when they need support and be willing to step up to carry more of the load when they can't.

"I subscribe to that philosophy, but also like the tension in the daily. We try not to run away from it, you run towards it because you know that that's going to help you get to that next level of togetherness, or just the seasons of life that kind of come at you," Curry said.

The couple, who tied the knot in 2011, share four kids. They first met as teenagers at church.

Curry said their relationship has gotten stronger as they've come to understand each other more deeply over time.

Even when things get rocky, "we're always working toward the same goal of being there for each other," he said. "And I think that's been such a rewarding experience through these almost 15 years of marriage."

This isn't the first time Curry has spoken about the importance of staying aligned in his marriage.

In a February interview with E! News, he said embracing life's challenges is an important part of making a relationship work.

"We always try to pride ourselves together on, 'When life throws something at you, make sure that it brings you together every step of the way and not tear you apart,'" he said.

His wife, Ayesha, has also been open about taking a similar approach to their relationship.

In February, she told People that she prioritizes her relationship with her husband over their four children.

"I think for us, our relationship always comes first. Then we're parents," she said. "And that works for us because then you have two happy people raising the kids in the house. So the family sector in our lives always comes first."
