Michael Phelps has garnered a lot of attention for-- well, mostly for his swimming prowess and numerous Olympic gold medals, a tally he just won't stop adding towards. But he's also getting attention for those weird dark circles that have appeared on his back.
The circles come from a technique known as cupping, and it isn't exclusive to Phelps.
Brian Campbell apparently does it, too.
I will attest to this. Am I in one of those pictures? https://t.co/UBzhg5Fc1k— Brian Campbell (@bcampbell_51) August 10, 2016
Apparently, Campbell's back actually is among those pictured!
Cupping is probably going to pick up in frequency, now, but at least Campbell can attest to doing it before it was cool.
