Harness Intensity for Emergency-Ready Fitness
Short, intense workouts, such as two 20-second sprints, create significant spikes in energy demand, simulating emergency situations that force the body to tap into its local sugar reserves (muscular glycogen). This approach is suitable for a wide range of users, including those with mobility challenges, allowing them to maintain cardio fitness effectively. The intensity of these sprints, while challenging, is brief, making it a practical method for achieving significant fitness benefits.
