AX Workouts is an Android app by Clemens Krug that provides a collection of the workouts published by Jeff Cavaliere on Youtube. The app is designed to help users remember the exercises and workout plans easily. The app is free to use and does not replace the in-depth explanations given by Jeff in the videos. It is assumed that users have already watched the videos and know how to perform the exercises. The app is constantly updated with new videos showing the exercises and further tips to the workouts to make it easier to follow along without having to go back to the Youtube videos.

In addition, the app can guide users through the workouts, allowing them to focus on the exercises and keep track of their overall workout time and rest periods. However, it's important to note that this app does not contain any of the workout plans available on the AthleanX website.

Overall, AX Workouts is a useful app for those who want to keep track of the workouts published by Jeff Cavaliere and follow along with their exercises. It's also a great tool for those who want to keep their workouts organized and structured.
