Editing Exercise intensity (section)

==Intensity Levels==
[[Exercise]] is categorized into three different intensity levels. These levels include low, moderate, and vigorous and are measured by the [[metabolic equivalent]] of task (aka metabolic equivalent or METs).
The effects of exercise are different at each intensity level (i.e. [[training effect]]). Recommendations to lead a healthy lifestyle vary for individuals based on age, weight, and existing activity levels. “Published guidelines for healthy adults state that 20-60 minutes of medium intensity continuous or intermittent aerobic activity 3-5 times per week is needed for developing and maintaining cardiorespiratory fitness, body composition, and muscular strength.”<ref>{{cite journal | last1 = Elmahgoub | first1 = S.
