I think that's essentially what online training is these days: a cheaper way to get access to a fitness 'sherpa' to guide you. Someone who lives and breathes this stuff to save you a lot of time and effort. Most of the real, practical, and current knowledge right now is spread across a variety of $1000 courses for personal trainers.

I'm in the process of building the largest online fitness database of its kind to democratize a lot of this information. I'm not sure what sort of business model I will pursue yet. But I want to collaborate with likeminded people and make the foundational information open to the public.
