Smartwatches include a function in which they can detect that you are training, even if you forget to register it, which through the technology and sensors that they incorporate are capable of discovering not only when your physical activity starts but what it is.
The different models on the market have a different number of sports modes, so your smartwatch can automatically detect that you are practicing certain sports, not all. For this reason, it does not hurt to inform yourself about what types of sports it can help you train in. Surely you will find the information you need before making your purchase to make the best decision if you like sports.

What is automatic training detection?
Automatic training detection is a function that you will find in many smartwatches and in some smart bracelets capable of automatically detecting when you are exercising and identifying the training mode that you are doing. When you activate it, your smartwatch will remind you to start exercising the moment it detects an increase in activity. It will do this only with the exercises that you have enabled.
Through this function, your smart watch determines the type of training and records a single exercise when you meet all the characteristics related to it during a certain time. This time may vary by model, but may occur after 10 minutes of continuous activity.
Of course, when you start the training, the time will start from the same moment in which it considers that the activity has started , so that initial time would also count and you will not lose a minute of your training, even if you get lost. Your smartwatch will notify you of everything, so you can act accordingly and effectively record your physical activity.

If you slow down considerably or are in a resting state, an end notice will appear after a few minutes. You can ignore it, pick up the pace, or indicate that you are no longer exercising.
Although it is not a perfect function, since it is not totally accurate, it is very interesting for athletes, and it is the means by which your smart watch is able to detect that you are exercising. Thus, it will be more difficult for you to forget to record your workouts.
