Adherence
Stand-alone use of commercially available smartphone fitness apps (immersive or non-immersive) does not significantly improve cardiorespiratory fitness or physical activity levels in insufficiently active adolescents compared to usual behavior.
Downloading a fitness app is not a workout. If you want to improve your fitness, you must use the app consistently (ideally 3x/week) and push yourself to the required intensity. Simply having the app installed and using it occasionally will not change your cardiorespiratory fitness.
