You may discover that certain physical activities that were once second nature are now proving to be considerably more difficult as you get older. According to a new Harvard Health study, sarcopenia (age-related muscle loss) “may begin around age 35 and occurs at a rate of 1 to 2 percent each year for the average person.” After the age of 60, it can accelerate to 3% every year. Muscle loss might be minor, moderate, or severe, or it can be within normal parameters.” Fortunately, you may avoid muscle loss by including a number of modest strength-training activities into your daily routine.
