This paper explores the impact of the application of the police polygon on the fitness status of the trainer, with an emphasis on agility, strength, endurance and coordination. The aim of the research is to assess the benefits of this type of training and to determine possible improvements in the physical form of the trainer. Police training courses are specific areas used to train police officers, but they can also be adapted for fitness training. Their structure usually includes various obstacles, treadmills, stairs, and other challenges that require different physical abilities. In this study, participants regularly participate in training at the police training ground for a certain period of time. During the research, data on the progress of trainers were analysed through agility, strength, endurance and coordination measurements before and after training. The results showed a significant improvement in all aspects of physical fitness after regular training at the police training ground. The trainers achieved better results in agility and coordination tests, indicating an increased ability to react quickly and to move accurately. Also, an increase in total muscle strength and endurance was observed, which was reflected in better performance in strength and endurance tests. In addition to positive results in physical condition, participants expressed satisfaction with training at the police training ground. They pointed out that this type of training provides a unique opportunity for experiential learning and knowledge of one's own physical abilities. In addition, emphasizing the diversity of obstacles and challenges, trainers expressed that during training they felt engaged and motivated to make progress. However, the study also identified potential risks and challenges associated with this type of training, such as injuries or excessive muscle strain. Therefore, it is important to properly conduct the training and ensure the safety of the trainers while performing exercises on the police training ground. The study showed that the use of a police training ground has a positive impact on the fitness status of the trainer, improving agility, strength, endurance and coordination. Participants had positive experience and satisfaction with training, but it is important to take into account safety aspects when conducting this type of training. This study provides the basis for further research and promotion of training at the police training ground in order to improve physical fitness and physical activity of trainers.
