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.
For example, if you are going to walk 2 miles every day, walking at the speed of 4 mph will burn more calories than 2 mph speed. However, if you walk 4 miles every day at 2 mph speed, you will be burning the same amount of calories of walking 2 miles at the speed of 4 mph.
