MOOSIC — While cupping therapy dates back to 1550 B.C., when it was used by ancient Egyptians, the form of alternative therapy was center stage at the 2016 Rio Summer Olympics. Athletes — most notably Michael Phelps — were sporting odd circular bruises on their shoulders and backs. And ever since the Rio Games, cupping seems to have been at the center of the athletic world. From Brazilian soccer star Neymar to North Carolina men’s basketball guard Joel Berry, more and more athletes are starting to use the ancient muscle therapy technique, which helps with pain, inflammation, blood flow, relaxation and well-being, according to WebMB.
