They believe their single-minded discipline and ability to endure pain and injury set them apart and mark them as special people, even heros, in a world gone comfortable and soft. Elite athletes who have become addicted to exercise, and to the lifestyle that is admired in their sports milieu, cannot see that they have fallen far from the goal of a healthy mind in a healthy body. They have become obsessive, compulsive, and vulnerable to permanent physical damage from minor injuries that they do not allow to heal by resting. After 3,500 hundred calories are burned per week, the health benefits decrease, and the risk of injury increases. Building and maintaining muscle and bone mass requires weight-bearing exercise.
Individual requirements vary depending on age and level of fitness.
We recommend you follow the advice of a competent trainer. Overdoing weight-bearing exercise can tear down muscle tissue instead of building it, and also damage bones, joints, cartilage, tendons, and ligaments. In summary For most of us, exercise is a good thing. It relaxes us and dissipates stress. It recharges our batteries so we can be more productive on the job and more attentive in relationships.
