With a GPS watch on your wrist, it's easy to keep track of your current location and speed, the direction and distance to your destination, and lots more.
A GPS watch is basically a little computer on your wrist that can track your location, speed, direction, altitude and distance. When this information is coupled with information on your heart rate when you are walking or running, it gives you extremely accurate information regarding your level of fitness. Most GPS watches with heart rate monitors also require users to enter information such as height, weight, sex and type of training (running, cycling etc). This information can then be extrapolated to precisely determine how many calories you are burning during training. Best of all you can compare your training over different days.
There are a number of sports Brands offering GPS watches and heart rate monitor combos. Prices can vary by hundreds of dollars and often this is due to the brand name and not the technology. Several GPS sports watches can tell you how far and how fast you are walking. The speedometers on them can be calibrated to get precise information regarding your walking or running. |
