This is how Apple itself describes it:
Walking is the most popular physical activity in the world, and one of the healthiest things we can do for our bodies. A walk can often be more than just exercise - it can help clear your mind, solve a problem, or welcome a new perspective. Even throughout this challenging period of time, one activity that has remained available to many is walking. With Time to Walk, we're bringing weekly original content to Apple Watch on Fitness + that includes some of the most diverse, fascinating and celebrated guests offering inspiration and entertainment to help our users keep moving through the power of walking.
Prince William has been announced as the next celebrity guest of Time to Walk, with his audio recording Apple Fitness +, which will also air on Apple Music 1. His Royal Highness has recorded a 21-minute audio for the service. It also adds a selection of 16-minute music. A total of almost 40 minutes for a good walk and clear your mind.
Prince William talks about the importance of stay mentally fit. He also reflects on a joyous moment when he was pulled out of his comfort zone, the value of listening as a way to empower others. An experience that led him to prioritize mental health.
It is just as important to maintain mental as well as physical health. In fact they are closely linked. For this reason, nothing better than taking care of one taking a walk being guided by the English nobility.
