Read Bill's blog entry and answer the questions. You won't believe it, but I've joined a gym! I joined in order to get fit. I usually spend half an hour on the exercise bike or the treadmill to build up my legs. I really like going there because it's cheap and it makes me feel good! Which sentence says ... 1 what Bill likes about the gym? 2 why Bill joined a gym? 3 what Bill does at the gym?
