I want to get in shape . I feel like a fence sitter-not really fat , but not really healthy .   I know what you mean . I fit into my clothes , but I'm not always comfortable .   Would you like to get in shape together ?   What do you have in mind ?   How about going to the gym ? There's one really close to work .   I know the one you mean . Do you know how much the memberships are ?   As a matter of fact , they are having a promotion right now .
