Cupping may be used to remove stagnation in the body and to promote blood and energy circulation.
Cupping is generally recommended for pain, tightness, gastrointestinal disorders, lung diseases (especially chronic cough and asthma), some forms of paralysis, although it does have application for other problems.
Did you see swimmer Michael Phelps cup marks during the Rio Olympics in 2016? Must have worked pretty well for his stagnation and getting his muscles working optimally judging by the medal tally he had.
