If you use Wordpress you can get the WODTogether plugin to embed WODs into your blog posts.
It does not create blog posts for you, but will pull in the WODs for each blog post you create. Most gyms just post a picture and caption each day, and the plugin will insert all the WODs from that day's whiteboard at the bottom of your post.
You can find the plugin by searching for "wodtogether" in the plugin repository in your Wordpress Admin backend or by downloading it here: https://wordpress.org/plugins/wodtogether-whiteboards/
Once installed, you will see a setting page under the Wordpress Settings -> WODTogether menu.
