Body mechanics refers to the way we move and use our bodies to perform tasks efficiently and safely. It involves understanding the principles of movement, posture, and alignment to reduce the risk of injury, especially during physical activities like lifting, bending, or reaching. Proper body mechanics can enhance performance and promote overall health. Key components of body mechanics include maintaining a stable center of gravity, using large muscle groups for heavy lifting, and keeping the load close to the body. Techniques such as bending at the knees instead of the waist can help protect the spine and prevent strain.
