Reina: Okay, I'm ready to walk my way to better fitness!
Lars: I'm glad you're so enthusiastic about starting to exercise.
Reina: I'm totally psyched! Check out my new tennis shoes.
Lars: They're brand new? You haven't broken them in yet? I hope you don't get blisters.
Reina: Stop worrying. Let's go, I'm ready to work up a sweat!
Lars: Wait. There are a few things you need to know before we start. It's a good idea to stretch and to warm up to avoid injuries.
Reina: I stretched already and as soon as we get started, I'll warm up slowly. Let's go!
Lars: All right, here we go, nice and slow.
Reina: Come on! How are we supposed to increase our heart rate if we walk this slowly? Pick up the pace!
Lars: I don't want to get shin splints. It's important that we start slowly and maintain a low-impact workout.
Reina: Forget it! I'll race you. The last one to the park buys lunch. Ready, set, go!
Lars: Wait!
