Fitness trackers are designed to accommodate a range of requirements. If you simply want to know how many steps you are taking each day, look for an all-day tracker. If you want details on the speed, pace, and stride associated with your steps, not to mention the route you traveled, look for a training tracker.
Fitness trackers range from simple to sophisticated, with prices to match. Before you buy, consider your fitness goals. Are you trying to jump-start a lapsed fitness routine? Fine-tune an exercise regimen? Train for a triathlon? The right fitness tracker can help you achieve your specific objectives.
