To upload a demo video for an exercise (either an exercise that the trainer has created or one of the nearly 1000 exercises FitSW has in its exercise library), start by clicking on the More button in the bottom right corner of the screen. (See image below.)
Once you are on the More page, click on the Exercise List category. (See image below.)
Next, click on the exercise that you want to upload your own demo video for. This can be one of the exercises that FitSW has in its exercise library, or one of the exercises that the trainer has created on their own. Once you have clicked the exercise, fill in the Demo field with the YouTube link of the demo video. (See image below.)
After you have added the link, click Done in the top right corner of the screen. Then, your video will have your demo video!
