First and foremost you can start sharing your blog posts to a direct and wider audience. But you don’t want to make this the sum total of all of your posting efforts, because it can get boring and tedious. Self-promotion only goes so far.
Change it up, just like you’d change up any good exercise routine.
You can also post pictures, for example. Get a photographer to work with you as you demonstrate certain exercises. That will make great photo content.
