As you get older, you may notice that certain physical activities that were previously second nature are now proving to be much more challenging. Sarcope­nia (age-related muscle loss) “may begin around age 35 and happens at a rate of 1 to 2 percent each year for the average person,” according to a new Harvard Health research. It can accelerate to 3% per year after the age of 60. Muscle loss might be slight, moderate, or severe, or it can stay within normal limits.” Fortunately, there are a variety of simple strength-training activities that you may include in your regular routine to help prevent muscle loss.
