You can change your default track to any of the tracks you have added. From the image below you will see 4 different tracks. In this case, the CFSBK track is the default track and was created automatically. Once you have created your other tracks, you'll be able to select which one you wish to be default. You are able to set multiple tracks as your default. But remember, all new members to your gym will get added to each track if all are selected.
