The app allows you to enter injuries and prepares a workout catered to your injuries. After you do a workout, the app asks for feedback on each exercise and if you found an exercise too difficult, the app will make adjustments to your workout.

    The workout was so easy to register and follow the directions. The trainer shows and explains at the same time what to do . The workout starts slow and adjusts to the person’s level of readiness for the next lesson. I haven’t exercised in years , this was a perfect start! It works well. This app is the best I tried . Only a couple reminders throughout the day. Simple and easy.
