You all know I am avid about walking up the stairs whenever I can, but I just learned the benefits of going down the stairs. Surprisingly, walking down stairs or even downhill reduces blood-sugar levels more than walking uphill. What a pleasant surprise! Having lower-blood sugar levels can help reduce your risk for developing type 2 diabetes. Walking up stairs is a good cardiovascular workout, but going both up and down stairs will help lower your LDL (aka bad) cholesterol. So don't skip doing down the stairs.
The only downside of going down, is that it can be hard on your knees. Walking down stairs and hills uses your leg muscles in an eccentric or lengthened position, which can strain the knee joint. Also, it is easier to trip on the way down so keep your eyes on the stairs.
