Foucault perceived individuals as being under the Gaze the body is a symbolism of societys ills. He believed in the concept of Jeremy Benthams Penopticon and tells us that we as individuals are constantly under control and scrutiny. Recommend you read Sue Bartky on Foucault and you will get a clearer idea. Foucault says that the units of society which regulate us are the hospitals, schools, prison and the Army. We are told what to do and how we should behave and we conform to the same because it is what is expected of us. With these controls in place we conform and eventually we become our own locus of control. It has been conditioned into us much like the psychological theory of pavlovs dogs. Hope this helps

Hi Maira

you can start considering two main issues in Foucault and Giddens works (and at the same time by considering they both changed their viewpoints about manhood during their lives). On the one hand Giddens, despite his enduring reflections on the social influences over the person, states that (self-)identity concerns a narrative continuousness. It's what he called "individual's biography" as something more and different in respect to behavior and others, something that makes our experience a continuum (http://goo.gl/MDnB8H). On the other hand Foucault tradionally affirms a concept of truth and society in which you cannot find any "innate" conditions or characteristics, but rather so many power dynamics that urge the individual to confront with the definited norms. So he covertly or overtly assumes that the identity is our way to "surf" over the cultural elites and the norms they impose. You have also to consider that his main focus was the impact of the "social" over the "individual". He mostly reflected on identity and personal dimensions in the  last part of his life/work. So he came back to Greek wisdom and specifically highlighted the choice each and every man can have in dealing with and defining his/her identity trhough what he defined as the "care of the self" (https://goo.gl/x2pWP2). That is somethinglike a training "against" normative influeces and trhough the discovering of our personal way of making sense of the world.

Giddens seeks to preserve the idea of agency against structure in his development of "structyration theory" - his understanding of self-identity needs to be placed within that, and his use of the concept of self-narrative is his attempt to capture this two-fold process. Foucault sees the self as a site where discourses of power/knowledge interact to shape identity collectively. Individuals may resist to craft themselves in the spaces between discourses, improvising and adapting an "Aesthetics of the self". Giddens reads Marx, Weber and Dutkheim, and some Freud, through phenomenology and hermeneutics; Foucault reads Kant and the Greeks through Nietzsche and Bstaille. 

Probably best to read both and make a judgement.

Broadly,Foucault approached self and identity as performances, based on ways of knowing and practicing that permeate through society as so many dominant and sometimes interlinking discourses. Accordingly, self and identity are social constructs, there is no inner or essential self or singular identity threading through the biology and sociology of the individual, the latter 'singularity' is an example of performing identity and self, no more no less. For example, being a father is a performance not the unfolding of a biological urge and sociological essence (although this performance is often inscribed by the latter). Giddens approaches self and identity as the dual performance of social agents and structures, with the emphasis on social agents weaving more or less enduring social structures from the intricate totality of social actions. The relationship, social structure and social agency feed off each other producing a dialectic of constraints and opportunities impacted by social class, gender, ethnicity, racism and so on. The concept of duality offers the space for identity and self to be both the work of social agents and of social structure. There is scope in Giddens to allow for identities in the plural and for a singular more enduring identity or sense of self, one's biography. The key seems to be the degree of social fluidity and structural change. Periods of social fluidity breed insecurities and risks to personal narratives as agents seek to perhaps re-establish or move away from existing identities. In this case begin a father may be an identity in flux. From different perspectives, Foucault and Giddens share the thought that identity and self are social constructs. One leans toward performance the other to the existential.
