You may be wondering what a Fitness Page is doing at a Materials Science and Engineering web site. Fitness is a very important part of maintaining a good outlook on life, and a great way of reducing stress. There are all kinds of practical, fitness oriented pages on the Internet. This one has a more theoretical flavour, mostly because I have the tools to be more theoretical and also to be a bit different. It is supported by diet.
Endurance is the cornerstone, upon which all our daily living is based.
What we do is limited by our ability to get oxygen into, and carbon dioxide out of, our bodies. Strength is our ability to temporarily produce more work than what we are normally producing. A man cannot do as much work as a draft horse over a long period of time, but we are capable of producing as much as 10 horsepower over a short period of time. Flexibility is defined as the range of motion present at a joint, in a specific plane and direction. Diet plays the supporting role in developing endurance, strength or flexibility.
