The Power of Ball-Based Physical Training by Jens Bangsbo (Patreon)

"Over the years, I had the opportunity to participate in many physical training sessions, which I later realized had limited value. This was either because the training had limited relevance to soccer, or because the improvements achieved in a specific aspect quickly faded due to lack of consistent practice. It is important that physical training is specific and efficient, enabling physical development that is relevant to soccer. This allows investing more time in training other aspects of the game, such as technical and tactical elements. A great way to achieve the desired effect is to incorporate ball work into physical training, especially through structured drills and other exercises. This approach will not only enhance the players' physical fitness but also develop their technical and tactical abilities, keeping them highly motivated."

"In order to cope with the physical demands and maintain technical performance levels throughout the game, it is crucial for players to sustain a high level of physical fitness. Regular competition helps maintain good physical condition, but additional physical training is necessary. This training should be specific to football, focusing on exercises involving the ball. Incorporating the ball into exercises ensures that the muscles used in soccer are specifically targeted, and it boosts players' motivation. Moreover, it allows for efficient use of often limited training time, as technical and tactical aspects can also be developed simultaneously."
