Fitness evaluation and exercise prescription. 
Proper exercise positively affects most of the risk factors of coronary heart disease and frequently enhances the quality of life.  Maximum exercise test evaluation is recommended for adults over 35 years of age prior to initiating an exercise program.  Key elements for an adult exercise program include activities for flexibility, muscular tone, and cardiorespiratory endurance.  Proper warm-up may improve performance and reduces the potential for injury.  Exercise motivation is enhanced by variation.
