Passage: I wake up in the morning and get ready for my day . I eat breakfast to make sure I have energy , and wear comfortable clothes . I drive to the gym close to where I live , and walk inside . Before I start working out , I stretch to make sure I do n't pull any muscles . Pulling muscles can hurt a lot . I decide to work out today by running , which is good for your heart . I jog for as long as I can , remembering to breathe enough so that I do n't run out of breath . I slow down and turn off the treadmill , and decide I 'm done working out for the day . I use a towel to wipe off my forehead , and leave the gym . Question: What do they start doing on the treadmill? Option1: Sleeping Option2: Jogging
Jogging
