Technology can play a big role in staying in shape.  Shelly Greenberg of the Rochester, Minn. Post-Bulletin recommends the Bodybugg used on The Biggest Loser.  It measures steps, calories burned, workout intensity, sleep quality and duration, and measurements of activity.  A step up from a regular pedometer is the FitBit Ultra (approximately $100). This device allows you to track your steps, and also includes an altimeter which measures distance you are climbing stairs or hiking. This device is to be worn near the waist and clips to the clothing, and provides an estimate of calories burned rather than measuring them.  I like MyFitnessPal, a diet and fitness community providing the tools and support you need to achieve your weight loss goals.
