Look for a threaded rod with an adjustment nut at the point where the lower rod connects to the upper one. You can adjust the length of the linkage by turning the nut clockwise -- to shorten it -- or counterclockwise with pliers. If the nut is stuck, hold the rod steady with a second pair of pliers while you turn it. Lengthen the rod if your tub doesn't have a stopper and it isn't holding water.
A 200-pound person burns about one-third more calories than a 150-pound person.) So a brisk walk, covering three-and-a-half miles in an hour, burns about 280 calories. When repeated each day, this excellent habit burns about 3,900 calories -- more than a pound of fat -- every 2 weeks.
One-Mile Walk. The calories you burn walking divided by the number of miles you walk equals the calories you burn walking one mile. For example, the 150-lb. person who burned 190 calories per hour walking 2 mph walked two miles and, thus, burned 95 calories per mile.
