Fitness and music are closely intertwined, creating the perfect combination for effective workouts. Music inspires new achievements, increases motivation and even promotes relaxation after training. Music also plays a key role in meditation and stress relief. Apps like Calm and Headspace use sounds to create a meditative atmosphere, and Endel creates personalized soundscapes based on biometric data, World Class reports. Music is an excellent source of motivation, lifts your mood and increases stamina. Choosing the tempo of the music can affect the intensity of your workout, and creating the perfect playlist can affect the overall experience of your workout.
