Recently, I have gotten into walking as a workout. It is a low-impact workout that doesn't hurt my back, and it requires no special fitness equipment. That makes it an inexpensive workout for sure. All I need is a good pair of walking shoes. My husband has started walking with me too, and really enjoys it as well. It's a good way to get in shape and tone up the legs without investing in a bunch of fitness equipment. It's actually a great way to relieve stress and feel more energized as well. I have been under a lot of stress lately, and walking has helped a lot. If I had to put money into fitness equipment, that would just add to my stress, and I sure don't need that right now. I got new shoes for walking and can walk even further now with no pain. I love that walking has so many great benefits. It's great for the heart and for the leg muscles. I love to walk to improve my health and fitness.
