Do you want to keep track of your progress while you work out? If you want to live a long and happy life, you must work out whenever you can. Exercise can bring many benefits to your body, including better flexibility and improved endurance. It even gives you psychological benefits whenever you do cardio.
There are dangers of over-exercising, though. Muscle injury and tearing are common occurrences to those who overwork their bodies. Buying a fitness tracker will help you avoid this by telling you when to stop.
