Navigate to the desired swim in your feed and tap on the sharing icon in the bottom right hand corner of the tile. This will show you the sharing options for Instagram; you can also tap “more” to see more sharing options. 

The swim will be shared as an image or as a link, depending on the medium you choose. If it’s a link, clicking on the link on a device with the FORM Swim App installed will open the app to show the appropriate swim session.
