Exercise, Labour or Work?

This posting will be based around a discussion we had in our tutorial class.  Hilary asked each of us to categorise our selected activity as either work or labour. I understand labour as an activity or duty essential for us to survive; "Labour is the activity which corresponds to the biological process of the human body"(Arendt, 1958). In contrast to this, I identify work as an activity selected by an individual, however one that is not essential to survive: "Work is the activity which corresponds to the unnaturalness of human existence" (Arendt, 1958).
 Maslow's Heirarchy of Needs identifies labour as a need (see diagram below).

After seeing Maslow's Heirarchy of Needs and definitions of work and labour, I would define exercise as work. I see exercise as work as it is not essential for survival, it is something I choose to partake in.
 Although I have identified exercise as work, this does not make it any less significant than labour. Exercise is able to provide me with many benefits; some of these benefits are identified on Maslow's Pyramid such as; fresh air while exercising (biological and physiological needs), achievement (esteem needs), meaning (cognitive needs), form (aesthetic needs) and self fulfilment (self - actualisation).
