Incorporating active rest periods into workouts serves multiple purposes, primarily enhancing recovery while maintaining an elevated heart rate. Active rest, such as low-intensity exercises or dynamic stretching, can help prevent muscle stiffness and improve blood circulation. This can lead to more effective muscle maintenance and reduced downtime between sets. It also aids in improving overall workout efficiency by allowing individuals to spend less time resting while still maximizing calorie burn. Furthermore, it maintains engagement and can enhance endurance over time.
