Træn med forsvaret is a fitness and training app that helps you improve your strength, endurance, and health. The app is based on the idea that every human being has a specific combination of muscles, bones, and nerves, which determine his or her physical abilities and fitness.

Every human being is born with a specific quantity of energy. This energy is used for movement, in order to perform physical tasks, and for muscle contraction. The more you use your muscles, the more energy you have.

The app is designed to help you use your muscles in a way that will improve your fitness and health. The app uses the same idea as the other fitness and training apps, but it is unique in that it is based on specific physical abilities.

The app is divided into three main parts:

The first part is the Fitness Test. The second part is the Training Program. The third part is the Exercise Library.
