And Senior Citizens Physical fitness is to the human body what fine-tuning is to an engine. It enables us to perform up to our potential. Fitness can be described as a condition that helps us look, feel, and do our best. The ability to perform daily tasks vigorously and alertly, with energy left over for enjoying leisure-time activities and meeting emergency demands. It is the ability to endure, to bear up, to withstand stress, to carry on in circumstances where an unfit person could not continue, and it is a major basis for good health and well-being.
Physical fitness involves the performance of the heart, lungs, and muscles.
And, since what we do with our bodies also affects what we can do with our minds, fitness influences to some degree qualities such as mental alertness and emotional stability. An optimal ratio of fat to lean mass is an indication of fitness. The right types of exercises will help you decrease body fat and increase or maintain muscle mass. That's how funny a potbelly isn't. Despite the comic relief afforded by the tummies of some very successful comedians, a loose abdomen is no laughing matter.
