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

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