As an affiliate I like names that describe what a site does using words people might search for. fitness and store don't go together too well, better if it were shop, fantastic if it were equipment.
Having said that, it should sell if you pitch it right, somewhere between 50-150. Then again what do I know I bought poorpeople.co.uk yesterday. :?
Hope that wasn't too honest for you, please feel free to comment on any names I post :smile:
