Go to the gym
STEVE: I'm going over to the gym. I want to do some running.
JOSEPH: Why don't you run outside?
STEVE: Are you kidding? Do you know how cold it is today?
JOSEPH: Yeah, I suppose. I guess it isn't healthy to run in this weather.
STEVE: No, it's not. Not at all. I'd probably freeze my lungs.
JOSEPH: Wait for me a minute. I'll go over to the gym too.
JOSEPH: Yes, why not? Just let me get my gym clothes together.
STEVE: I didn't know you could exercise.
JOSEPH: What do you mean by that? Everyone can exercise!
STEVE: Yeah, I know. But you? I always thought you were only good at lifting beer bottles to your mouth.
JOSEPH: No, not at all. I was on the swimming team in high school. And I'd like to do some weight training. They have decent equipment at that gym.
STEVE: You're going to lift weights? Hah!
JOSEPH: Are you laughing at me?
STEVE: I'm sorry. I just can't imagine you lifting weights.
JOSEPH: Maybe not. But I want to start. I need to get in shape. I feel these past couple months my energy is low.
STEVE: It's true. If a person doesn't exercise, they get sluggish. That's why I keep running. Even in the winter.
JOSEPH: Well, then maybe I need to change my character, don't I? I don't want to become a fat slob.
