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.
Walking Calorie Burn Rates. How many calories you burn when walking will depend on your speed, the terrain and your size. A slow, 2-mph pace burns 204 calories per hour for a 180-pound person. But, if that person doubles the speed to cover four miles in an hour, she can burn 409 calories. Take the walk uphill for the entire hour, and burn 490 calories. Smaller people burn fewer calories -- a 125-pound person uses 270 calories in an hour long, 4 mph walk. Larger people burn more -- a 185-pound person burns 400 calories walking for an hour at 4 mph.
