Dina: All right, in order for this to work, it is critical that we run at the crow at exactly the same speed, 8 miles per hour, got it?
Mateo: Yes, ma'am.
Dina: All right.
Mateo: Actually, I don't know how fast that is.
Dina: Sorry, sometimes I forget you're Asian. 13 kilometers per hour.
Mateo: I still don't...
Dina: It's 240 steps a minute.
Mateo: That doesn't mean anything to me.
Dina: Well, I don't know how to make it any clearer.
Mateo: You're just saying just run pretty fast, right?
Dina: "Pretty fast" is a relative term. What's your resting heart rate?
Mateo: I have no idea.
Dina: God, we're gonna have to figure it out now. Okay, take your pulse for ten seconds. You're gonna multiply that number by six.
