You are currently not able to set up multiple profiles under one account.
If you wish to track your progress separately, you need to set up an account per person as data needs to be personalised for the stats to be accurate for you.
If you have the free version of Fiit, you could connect Fiit to your TV so more than one person can take a class at the same time. It's easy to get your friends and family involved, try a group class so you can take with friends and family - Learn more HERE
With a Fiit subscription, your tracker device is linked to your personal membership and calibrated to your heart rate, so the metrics for tracking your calories burned, reps and Fiit Points can only be tracked for you. If two people or more people take a class together, the class will only connect to one Fiit device and therefore only record the stats for one person.
For a truly personalised experience, we recommend that you have your own membership. This will enable you to see your progress and achieve your personal fitness goals!
