In answering this question, a strategy would be to tailor your answer, the best you can, to the position that you are seeking. Try to make the connection between what you enjoy doing outside of work to the requirements of the position. e.g.

If, outside of work, you are involved in any team functions, that may also be wise to note. Companies are always seeking people that they feel will work well with the existing staff. So, by mentioning your involvement with a team outside of work, this would show that you could adapt to the employees of the company.
