Whether you use Sworkit on your phone or in your web browser at https://app.sworkit.com/collections/kids-workouts the content is the same. You can choose from nineteen categories of activities. The categories are arranged by age group and activity type. After you've selected a category you can then choose the length of the activity. Once you've made those two selections Sworkit will show a demonstration of the physical movement to be done and set a countdown timer for doing the activity. If you've chosen an activity length of more than a minute you'll be shown a few different physical movements to complete.
