I want to warn you about the incompetence of the creators of this app. the people they hired as specialists. In either case, the workout programs were created by people with no understanding of healthy living. There is a pronounced lack of balance in training, nutrition, and rest. I am sure that all the advice was given negligently, on the knee, with minimal loss of time and money. Without thinking at all about people's health. Save your health, don't use it!
