metabolic stress

Metabolic stress occurs when the body's energy systems are heavily used, often during intense exercise or limited nutrition, causing a buildup of waste products like lactic acid. This stress triggers adaptations in muscles and cells, boosting strength, endurance, and metabolic efficiency over time. It’s a natural response that encourages the body to become stronger and more resilient by improving how it produces and manages energy. Essentially, metabolic stress is a sign that your body is working hard to adapt, leading to better physical fitness and health.
