Incorporating cardio into a fitness routine effectively enhances cardiovascular health and burns calories. Best practices include selecting enjoyable activities, such as running, cycling, or dancing, to ensure consistency. Aim for at least 150 minutes of moderate-intensity or 75 minutes of high-intensity cardio each week. Gradually increasing intensity and duration can prevent injuries, while varying workouts keeps the routine engaging and can enhance performance. Incorporating interval training or cross-training can also be beneficial. Always consider personal fitness levels and consult a professional for tailored advice, especially if starting a new regimen.
