When you join your gym on CrossFit btwb you are automatically placed into your Gym's "Squad." You will be able to message your friends at your Gym and easily interact with their workout posts. 

You can react to a specific post, click on “Like” and then tap an Emoji that you want to "give" the person. To add a comment on the post type a message in the comment field. 

As well as automatically being added to your Gym's Squad, you can also create and name your own Squad. You can search for your friends from your Gym and add them to your own Squad.

You will be notified of recently logged PR's, messages, and general activity in your Squads. This makes it easier to go in and give your buddy a thumbs up for that PR they just hit.

Check out the video below on how Squads work.
