Where to place google adsense.

I have adsense at the top of my homepage: http://breakingbad.co.uk/, but nowhere else. My template cant be edited so I cant put them in the template. I was wondering if someone who knew the rules of adsense knew where I could put more adds eg. if its possible to put them in beetween every x posts or something. Thanks, Rob.
