If you saw all those dark red spots on athletes backs, including Michael Phelps. They look like giant hickeys.
They aren’t. It’s the result of cupping. According to the story I found on CNN it is a “great recovery tool”.
Michael Phelps showed some of it in his Under Armour Commercial.
If you are wondering what cupping is. According to CNN it’s not new. It dates back. WAY BACK.
The practice of cupping has been mentioned in ancient Greek and Egyptian texts.In traditional Chinese medicine, cupping dates back at least 2,000 years, according to a 2012 analysis published in the journal PLOS One.It is believed to restore the flow of “qi” — the life force.In recent years, cupping therapy has been used for people suffering all sorts of ailments including shingles, facial paralysis, cough and difficulty breathing and acne. But cupping is most commonly used to treat pain, according to the analysis.
