No single factor determines when an individual can begin jogging. A person can walk about 4 miles briskly but it unable to reach the target heart rate range by walking should consider a jogging program to make additional improvements. Also the ability of the individuals joints to withstand additional stresses should be considered.

Common faults of the beginning jogger include breathing with the mouth closed, insufficiently bending of the knee during the recovery phase, and swinging the arms across the body.
