Build a course to monatize your knowledge. See the live example of a fitness course by Kevin Kreider from Bling Empire on Netflix.
This can be the start of your course for payment or logins. OR you can build a landing page or funnel using Hyax to sell your course then just link to this page for students to get started.
Once they purchase on a landing page or a course page they are auto-logged in to have access to all the content and course assets.
Make course sections and multiple lessons then make them free or paid for students → Live Page
