I'd just started working on a new site about exercise and physical therapy I'd like some tips and advice on how to make my site pay for itself and maybe more. I already started google adsense and amazon affiliate. how can I optimize these? I would also appreciate tips on layout an the general look of the site. You can find my site here

grateful for any replies!

thank you

Thanks, I appreciate the advice and quik reply, I've done a quite few changes already (look here).
About the theme, I agree it might be a bit boring but I don't want it to flashy cause i want the site to send out signals of a certain degree of seriousness and authority.
Thanks for the tips on spreading links:-)
