W: Hey, Mark. I never noticed that belly of yours. What have you been up to?
M: It’s all the beer. I hang out with friends a lot lately. I need to start working out again.
W: That reminds me. I should have hit the gym today.
M: Where do you work out?
W: At Bally’s. It’s pretty close to home so it is convenient.
M: How much are you paying?
W: I only pay 20 dollars a month after I become a member of it. The membership costs me 200 dollars per year.
M: That’s pretty good. I think I should join too.
W: If you join, we could work out together. It’s so much better working out with another person. It’s hard to motivate yourself when you are alone.
M: How is the facility there?
W: It is fantastic! The inside facilities are the usual stuff but since it was opened last year, it even includes a health-shop, a snack bar, a member lounge and two cafés.
M: Sounds perfect! What do you usually do in the gym?
W: I usually spend about 20 minutes on the treadmill, and then lift weights for about an hour.
M: Do you go every day?
W: No. I try to go 4 times a week, but lately, I’ve been only going about 2 times a week. That’s why I need you there. You should join.
M: There are so many girls working out in a gym nowadays. What do they usually do?
W: Though some prefer rowing machines, stationary exercise bikes, and treadmills, the truth is that the most popular exercise for them is yoga.
M: To be frank, I like yoga. So I’m signing up tomorrow.
W: So you’re really going to join?
M: Yeah. Let’s go in tomorrow and I’ll sign up. We can work out together.
