One of the biggest fitness gadget trends right now are all of the fitness activity trackers to wear on your wrist. You may all remember the basic pedometers that you would wear located on your hip attached to your pants to track steps. While those pedometers are still great to wear to gauge your steps throughout the day - the newer fitness trackers will keep track of your steps, distance, calories burned, sleeping patterns, allow you to enter a food log, and many other features.
So the days of just the basic step counter are long gone. Most people prefer the new trackers as they are able to save their activity on their phone or computer. With that said it is easy to share your results with others to lead to a little competition to see who can walk the most steps and/or burn the most calories throughout the day. It's a good way to keep yourself accountable and to also have others keeping you accountable, too.
Some of the top rated fitness trackers now are the FitBit Force, Nike FuelBand SE, Garmin vivofit, and the Jawbone UP24. All of these trackers are great, but it just depends on what functions you prefer to have. The Garmin vivofit is the only true waterproof option. So if you are looking to use a tracker while swimming the Garmin would be the best choice.
The FitBit Force and Fuelband SE are the highest sold trackers and have very similar functions. If you have not actually used one of them before, I would recommend that you try them both out before fully deciding on one of them. Some people find the FitBit easier to use while others prefer the use of the Fuelband. One feature that is different is that the Fuelband SE doesn't have a stopwatch function. Fitbit has a longer battery of 3-6 days longer than the Fuelband. The Fitbit is compatible with an Android phone and and iPhone, whereas the Fuelband only works with an iPhone. So stay away from the Fuelband if you have an Android phone.
Several trials have been done to test the accuracy of the step counting on these devices and they all gave varying results based upon the activity. So overall, if the functions are easy for you to use and fit your exercise routine, then that particular option is best for you. So go try them out and see what fits you the best.
