High-intensity workouts can significantly boost metabolism during and after exercise. Known as Excess Post-Exercise Oxygen Consumption (EPOC), the body continues to burn calories post-workout to recover, resulting in increased fat oxidation. These workouts enhance cardiovascular and muscular endurance while promoting greater calorie expenditure over time compared to moderate-intensity sessions. This effect is especially beneficial for individuals looking to lose weight or improve their fitness levels. High-intensity training also often leads to greater adaptations in muscle and cardiovascular function, allowing for overall improved athletic performance.
