Starting from 40 years old, we lose 5% of our muscle every decade. At 80 years old, many seniors are falling down because they lost around 20% of their muscle. Sarcopenia, defined as loss of muscle, is a common issue for all the seniors. As prevention, we use this connected grip ball to detect your risk of sarcopenia. With our smart grip ball, you can do a grip test at home any time you want. Family members or caregivers can also see your test results in real time on their mobile APP, and be alerted when the indicator is out of normal range. In addition, you can use it to exercise your grip strength whenever you like, as a way to prevent the occurrence of sarcopenia.
