Metabolic conditioning refers to a type of training designed to improve the efficiency of energy production within the body during exercise. It typically combines high-intensity exercises with minimal rest, promoting both aerobic and anaerobic capacity. This training stimulates metabolic pathways that aid in energy release from carbohydrates and fats. Essentially, metabolic conditioning helps enhance overall fitness by increasing endurance and power, making the body more effective at burning calories in various states. The principles behind it aim to challenge both the cardiovascular system and musculature simultaneously for better performance.
