Easy runs are a type of exercise that can be done at any level of physical fitness. JOGS, which are four letters long, are a slow, steady run that is easy on the body and can be done for a long period of time. Lopes, which are five letters long, are a slightly faster run that requires more energy and can be done for shorter periods of time. TROTS, which are also five letters long, are a faster run that requires even more energy and can be done for even shorter periods of time. All three types of easy runs are beneficial for improving cardiovascular health and overall fitness.
