Extended Summary:
Posture refers to the structural alignment of your spine and limbs to maintain balance, resist attacks, and apply techniques efficiently. Good posture minimizes vulnerability and maximizes control. In positions like closed guard, staying upright with a straight back and chin down helps prevent sweeps and submissions. In passing and standing, posture improves mobility and power. White belts must learn to avoid breaking posture (e.g., rounding the back) and instead develop active posture using core tension and positional awareness.
