I think I should join a fitness centre . I am getting a little fat and I'm totally out of shape . Even a quick walk of a few hundred metres leaves me out of breath .   I'm afraid you are beginning to look a little overweight . You really need to stop smoking . That's the main reason you're unhealthy .   I guess you're right . I've tried stopping , but I just can't seem to quit .   Why don't you try smoking one cigarette less each day ? How many do you smoke each day now ?   I smoke around 30 each day .   Ok . So for one month , reduce the number you smoke by one a day . At the end of the month , you'll have quit . You should also buy a tracksuit and go jogging every morning . You don't need to jog far .   If I do a few exercises at home , like crunches , I'll soon deal with this waistline .   Be careful when you go jogging . Don't put yourself under too much stress . You're still a smoker shouldn't do too much exercises in your condition .
