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. 
STEVE: You?
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 that 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: So I need to do something too. 
STEVE: But lifting weights isn't the best thing.
You should do some kind of aerobic exercise.
JOSEPH: I know. But I want to start today with a little weight lifting.
Then I'm going to buy a new swimming suit and goggles,
and every other day I'm going to go swim laps in the pool. How does that sound?
STEVE: It sounds like a good plan to me. I'm still... I mean...
JOSEPH: What?
STEVE: I'm still just surprised you really want to do it.
It doesn't seem to go with your character.
JOSEPH: Well, if that's true, then maybe I need to change my character, don't I?
I don't want to become a fat slob.
