Fascia is a connective tissue that envelops and compartmentalizes muscles and other organs within the body. The primary role of fascia is to protect and support individual muscles by providing a structural framework that helps maintain muscle integrity and organization. This connective tissue not only ensures that muscles can function optimally but also serves to reduce friction between muscle layers during movement.

The importance of fascia lies in its ability to keep muscle fibers aligned and functioning effectively while contributing to the overall biomechanics of movement. In addition to supporting muscles, fascia can also play a role in proprioception, allowing the body to sense its position in space, but its primary function is as a protective and supportive structure. This understanding of fascia's role is crucial for personal trainers when considering how to implement effective training programs that respect and enhance the flexibility and functionality of this tissue.
