During the Olympics, USA swimmers have been seen with dark circular marks around their bodies.
It looks like Phelps either lost a fight with a vacuum cleaner or is having way too good a time in Rio, but the marks are actually a result from cupping therapy.

For the past couple years, swimmers such as Nathan Adrian and Natalie Coughlin started turning to the ancient method found in China and parts of the Middle East to aid their recovery.
Cupping involves heated glass cups that are applied to parts of the body. The temperature of glass creates suction that supposedly helps treat pain and relieve muscles of knots and swelling.
