Massage developed alongside athletics in both Ancient China and Ancient Greece. Taoist priests developed massage in concert with their Kung Fu gymnastic movements, while Ancient Greek Olympians used a specific type of trainer ("aleiptes") who would rub their muscles with oil. Pehr Ling's introduction to massage also came about directly as a result of his study of gymnastic movements.
The massages are geared towards athletes and their sports. For instance, working on a runner will require doing a lot of leg work, but the upper body work will be minimal. Moreover, massages will target those areas that tend to become injured. For example, a massage session with a tennis player will involve a forearm massage that is preventive in the development of tennis elbow. If necessary, a whole session could be spent only on important areas, and skip completely muscles that are not overused in a particular sport.
