Cardio Intervals: Short Bursts for Big Results

Cardio intervals involve short bursts of high-intensity exercise followed by periods of rest or low-intensity activity, delivering significant fitness benefits in a short time. For example, sprinting for 30 seconds followed by 60 seconds of walking, repeated for 15-20 minutes, elevates the heart rate and boosts metabolism. Other effective interval exercises include cycling, jumping jacks, and burpees. These intense bursts improve cardiovascular health, increase calorie burn, and enhance overall endurance and speed. Cardio intervals are an efficient way to achieve big results with minimal time investment.
