Physical training has been present in human societies throughout history. Usually, it was performed for the purposes of preparing for physical competition or display, improving physical and mental health, and looking attractive. It took a variety of different forms but quick dynamic exercises were favoured over slow or more static ones. For example, running, jumping, wrestling, gymnastics and throwing heavy stones are mentioned frequently in historical sources and emphasised as being highly effective training methods. Notably, they are also forms of exercise which are readily achievable for most people to some extent or another.
