muscle mass

Muscle mass refers to the amount of muscle tissue in your body, which contributes to strength, stability, and overall physical function. It is made up of muscle fibers that contract to produce movement and support your body. Maintaining or increasing muscle mass can improve metabolism, balance, and posture, and aid in everyday activities. Factors like exercise, especially resistance training, and proper nutrition play key roles in building and preserving muscle tissue. As people age, muscle mass tends to decline, which can affect mobility and health, so it’s important to engage in activities that support muscle maintenance.
