Different exercise modalities, such as cardio, strength training, and flexibility exercises, target various muscle groups uniquely. For instance, resistance training primarily focuses on creating muscular adaptation by challenging specific muscle groups through lifting weights or bodyweight exercises. Cardio exercises, like running or cycling, engage large muscle groups to improve cardiovascular health. Meanwhile, flexibility workouts, such as yoga or stretching, enhance the range of motion in muscles and joints. Incorporating a variety of modalities ensures a balanced fitness routine, promoting overall strength, endurance, and flexibility, while reducing the risk of injury.
