WP mobile theme that is for a training site *not* for a blog

Seems like every WP theme I can find is centered around blogging. But I do not want a blog. I am trying to create a training site. I would also like this to work well on mobile devices.

What do you mean by a “training site”?

Personal training? Instructional workshops? Something else?

Maybe author means the training site as a platform for web design beginner? In this case every simple WP template is suitable.
But if he wants to make a site about fitness, it will be better not to find a free templates but simply order the design and coding.

I’m just wondering what makes his “training site” so different where a typical wordpress theme wouldn’t work.
