Think that muscle loss is inevitable??? Harvard has another take on it.
"No matter how many birthdays come and go, muscles perform the same type of action. But as muscle mass in the body shrinks with the passing years, strength also declines. Sarcopenia—the gradual decrease in muscle tissue—starts at around age 30. The average 30-year-old can expect to lose about 25% of muscle mass and strength by age 70 and another 25% by age 90.
Some of these changes stem from the physiological effects of aging, but disuse plays a bigger role than many people suspect. Studies of older adults consistently prove that a good deal of the decline in strength can be recouped with strength training........:
