Physical fitness is improved by manipulating the mode, frequency, intensity, and duration of exercise and its rate of progression. Well-documented guidelines can assist the primary care physician in outlining training programs for their healthy patients who wish to begin an exercise program to maintain or improve their physical fitness.
通过控制运动的方式、频率、强度、持续时间及其进展速度，可以提高身体素质。有充分记录的指南可以帮助初级保健医生为那些希望开始运动计划以维持或改善身体素质的健康患者制定训练计划。
