Researchers found a significant improvement in walking speeds and ability to climb stairs after several weeks of weight-lifting. The new data confirm results from a smaller sampling of older Americans studied four years ago, which indicated that the onset of physical disabilities during the later years of life was due in part to a loss of leg muscle.
