Yup, i agree with adam. If you want to increase your adsense earnings you'll have to work on SEO and social media marketing to increase your traffic. The more people that visit your blog, the better your chance for clicks become.

Then you also have to make sure that you're putting out great content on top of just SEO for traffic. Because even if you rank at the top on google, if you don't have anything on your blog/site that'll hold the attention of the readers/viewers then they'll jump off to another site.

I looked at your blog and it seems like you're geo targetting like me. look at what locals are searching for. You can do this on google's keyword tool, that's waht I use. It's actually pretty easy to rank for local search terms so you've got that going for you. The problem with local traffic though is the lack of high paying advertisers. So the ads that'll come out on your ads will pay really low.

I actually don't use adsense for my fitness blogs because nobody clicks the ads lol. I use nuffnang philippines and have ads that earn me based on the number of unique views as opposed to the number of clicks. You might want to look for a similar ad network in your country.
