I bought a smart watch last week. At first glance it looks useful, and attracts your attention. I bought it with my friend and we decided that we should start to exercise, because I realize that I got weight so much because of pandemic lockdown. When I tried to wear my T-shirts’ and short, I saw that my body was really in bad shape. So that I have started to make exercise since last Monday. But I searched good motivator to do this decision make real, and I found this smart watch. It is not only for my sporting activities but also helping my reminders. It warn me to not to forget drink water. However it helps me so much, I have some concerns about using it. As I am not good at technology, I thought that I bought it so much expensive. Finally, I want to share that it looks after my heart rate routinely, and announce when it detects upper limit. It will warn me not to push so much when I am exercising.
