Cardio exercises have a different impact on muscle mass compared to anaerobic exercises. While cardiovascular workouts primarily focus on improving endurance and calorie burning, they can lead to muscle loss if performed excessively without adequate strength training. On the other hand, anaerobic exercises, like weight lifting and resistance training, are designed to build and maintain muscle mass, improving strength and metabolism. To achieve a well-rounded fitness routine, it is essential to incorporate both cardio and strength training, allowing for a balanced approach that promotes overall fitness and muscle preservation.
