The timeworn expression "You're never too old to . . ." (fill in the blank) often rings true -- especially when it comes to exercise.
A new study by Spanish researchers found that 90-year-old men improved balance and muscle mass after completing a 12-week regimen of weight training. The men also increased their walking speed, lowered their risk of falls and found it easier to do daily physical tasks.
And a University of Alabama at Birmingham study of women 60 and older also found that weight training and aerobic exercise improved strength and balance, but researchers noted one surprising result. Older women can get the benefits even if they exercise just one day a week. The study's lead researcher said it appears that "doing a little bit of exercise can go a long way."
