For sample adults who had participated in weight lifting in the past 2 weeks (EXLIFT), EXLIFTMIN reports the average number of minutes respondents had spent weight lifting each time they had engaged in that activity over the past 2 weeks.

After determining that a respondent participated in weight lifting, respondents were first asked, "How many times in the past 2 weeks did you weight lift?" (EXLIFTNO). They were then asked, "On the average, about how many minutes did you spend weight lifting each time?" EXLIFTMIN reports the answer to this last question.
