A pedometer is an electronic device that counts each step a person takes by detecting the motion of his/her hips. Because the distance of each person’s step varies, an informal calibration of the pedometer is required. Originally used by sports enthusiasts, pedometers are now becoming popular as an everyday exercise measurer and motivator, especially digital pocket pedometers. They are used by fitness instructors as part of workout programs and by anyone who wants to track the distance he/she is walked a day. By the way, a total of 10,000 steps per day (about 5 miles/8 km) is recommended for an active lifestyle. There are different types of pedometers out there – stand-alone devices and ones that are integrated in personal electronic devices like smartphones. And some of these digital pocket pedometers are delivered with USB connection and computer software for activity analysis. Here you can find some of the most recommendable models.
