I found these really cheap on ebay and put them on my health wish list. I try and walk 2 to 5 miles a day. Not only is walking great for digestion, it’s also great for a bathing suit butt, cheaper than a gym, and reduces stress. I like listening to new bands, or a health-related audio book when I walk. Then, not only am I getting a workout, but I’m also learning about an awesome band, or the latest health information. I also like this Pedometer app, so I can keep track of how long and far I walk. The app I linked is free, but I upgraded because I liked it, and I wanted more GPS features, plus it keeps track of your walking history.
