Aerobic exercise involving running at an easy pace. Jogging (1967) by Bill Bowerman and W.E. Harris boosted jogging's popularity for fitness, weight loss, and stress relief. Many medical authorities endorse jogging, but others warn of risks to feet, shins, knees, and backs. Jogging only every other day, warming up properly, and using well-designed shoes and proper technique can reduce risks.

In the United States jogging was also called "roadwork" when athletes in training, such as boxers, customarily ran several miles each day as part of their conditioning. In New Zealand during the 1960s or 1970s the word "roadwork" was mostly supplanted by the word "jogging", promoted by the coach Arthur Lydiard, and this form of running became quite popular among many people at that time. University of Oregon track coach Bill Bowerman, after jogging with Lydiard in New Zealand, brought the concept of jogging as exercise to the United States in 1962. Bowerman published the book Jogging in 1966, and later updated the book for a 1967 republication. Bowerman established jogging programs for men and women of all ages. The popularity of these programs helped to spread the concept of jogging as an exercise for everyone throughout the United States.
Jogging is often used by serious runners as a means of active recovery during interval training. The runner who may just have completed a fast 400 metre repetition at a sub-5-minute mile pace, may drop to an 8-minute mile pace for a recovery lap.
Like other types of aerobic exercise, jogging is an excellent means of improving cardiovascular health, bone density, and physical fitness.
