Hardcore Lifting Business Idea

I’m making a business plan for my intro business class, and can’t seem to find any industry info and market research on the fitnes industry without having to pay for it. Anyone know where I can find some info on this stuff?

i dont know if this could help?

Look at Government sites. They can’t charge you for the info they have.
