Fascia is a three-dimensional network of connective tissue that extends from head to toe, from front to back, and from inside to outside, giving the body its shape and structure. Depending on lifestyle, personal movement patterns, and genetic predisposition, fascia varies from person to person. Lack of movement and repetitive, one-sided movements at work, in daily life, or even during sports can cause fascia to thicken, become inelastic, and stiff. This restricts movement and can lead to pain. Fascia training in water utilizes water resistance and buoyancy to maintain the elasticity and suppleness of the fascia through targeted, slow stretching exercises, without relying on muscle strength. Furthermore, it improves mobility, coordination, and balance, and there is no risk of injury, even for beginners.
