Coal trucks barrel past Mingo County's Little Dove Baptist Church, but the Fitness and Fellowship group found a way to walk anyhow. Fifteen times around the church is a mile. Since June, the group has scored big drops in blood sugar, blood pressure and weight.

Before they walk, participants stretch with exercises they got from the Arthritis Foundation, mixed with "whatever makes us feel good," said 90-year-old regular, Arva Reynolds (right).

Six months ago, Wanda Maynard, 72, could make it halfway around the church once. "Now I get around six times without puffing," she said. She has cut her insulin dosage by more than half.

"This program has brought us all so much closer," said Karen Reynolds, right. "We're taking care of each other's health. That's really motivating."
