👉 Leg fluid, also known as lateral fluidity or lateral mobility, refers to the range of motion and flexibility in the legs, particularly the hips, knees, and ankles, that allows for smooth and efficient movement. It involves the ability to bend, twist, and rotate the legs in various directions without restriction, which is crucial for activities like walking, running, and maintaining balance. This fluidity is achieved through a combination of muscle strength, joint mobility, and proper alignment, and it plays a significant role in overall physical performance and injury prevention.
