While the most common application for each is likely to be walking, running, cycling, and other cardio-based workouts, they’re also great for sport-specific workouts like tennis, or more general weight training.
“[Fitness trackers are suitable for] anyone who wants to track their progress and vary a good balance of exercises. Being able to find the right mix of  moderate, vigorous, and high-intensity workouts is suited for fitness enthusiasts at all levels,” notes  Rachael Babiracki, Head Trainer at Les Mills US.
Most fitness trackers can record a variety of exercises, but if you wanted a bit more detail or specific workout-focused apps, then it might be worth opting for one of the best fitness watches instead. The Apple Watch or a tracker running Google’s Wear OS can introduce additional apps focused on specific workout types.
