Preserve Strength

Many people have never not done enough strength training or built enough muscle mass to avoid falls as they get into their late 70s and early 80s. But there's some good news from Tufts University.

Researchers studied the diets and blood and urine of 384 men and women with an average age of 65. The results showed that a higher intake of foods rich in potassium, such as bananas, oranges, spinach, and tomatoes, may favor the preservation of muscle mass in older people.

The best way to increase strength and muscle mass is with a total-body resistance-training program two to three times per week. But to preserve those hard-earned gains, follow up your workouts with a healthy diet that includes lots of fruits and vegetables.
