What is the easiest aerobic exercise recommended for beginners?

Walking is often considered the easiest aerobic exercise for beginners due to its accessibility and minimal requirements. It doesn’t require any special equipment or training, making it an activity that most people can start immediately. Walks can be done nearly anywhere, whether it's outdoors in a park or on a treadmill, and the intensity can be easily adjusted by varying the pace or duration. As a low-impact exercise, walking is gentle on the joints, reducing the risk of injury, which is particularly important for those who are just starting out or returning to physical activity after a period of inactivity.

Additionally, walking provides cardiovascular benefits and helps improve overall fitness while still being manageable for individuals of all ages and fitness levels. This makes it an ideal starting point in developing an exercise routine that can be gradually progressed as endurance and strength improve.
