The main focus in this article is to analyse representations of body and class in strength sport and boxing in a Swedish context during the period 1910-1960, as well as their deeper societal meanings. The concepts of profession, body and class are understood in close connection to the theoretical concepts of value and capital. This study's understanding of class and group affiliation differs from more traditional class analyses. It is argued for an in-depth understanding of how such processes take place and work through a broader concept of class. Representations are examined through magazines closely connected to the sports, as well as identification through autobiographies, written by prominent athletes during the early and mid twentieth century. The study shows a close link between these sports and manual labour. Physically strenuous work functioned both as a training regime in itself but was also presented as a way to be 'discovered'. However, the close connection to the working class and manual labour groups meant that physical strength came to be seen as something natural. Sporting success was also locked into body capital, which also had a relatively low exchange value in relation to other forms of capital.
