Lean muscle refers to muscle tissue that is free from excess fat. It is important for overall health and fitness, as it helps improve metabolism, supports joint function, and enhances physical performance. Building lean muscle typically involves a combination of strength training and proper nutrition, focusing on protein-rich foods. To develop lean muscle, individuals often engage in exercises like weightlifting or resistance training. These activities stimulate muscle growth while minimizing fat gain. Additionally, maintaining a balanced diet that includes adequate protein, healthy fats, and carbohydrates is essential for supporting muscle recovery and growth.
