Great! Walking is such an awesome activity! It helps relieve stress, gives you time to meditate, allows you to experience nature and the outdoors, builds both muscle and cardiovascular endurance, and improves your mood. There are absolutely no negatives with walking! It also takes no special equipment.
The more you walk the easier it becomes. Walking helps you lose weight and as you lose weight walking becomes easier
I'm just getting home from a nice long walk myself and feel great!
