Aerobic Workout Never too late

Take heart from remarkable studies showing that people aged 85 could improve their aerobic capacity by as much as 20 percent by following a 12–16 week program of exercise in which the heart rate reached more than 75 percent of its maximum aerobic capacity. For optimum results, aim for an hour’s exercise a day: women in their 70s who did so in a study at a US university demonstrated aerobic abilities of women 30 years younger.
