You've probably seen a lot of news organizations, even like us at 9NEWS, doing a story about the bizarre red dots that are showing up on Olympians in Rio.
You've also probably heard from different people about how this bizarre therapy called "cupping" actually helps blood circulate, and relieve muscle tension.
The Next team went to ask psychologist Dr. Max Wachtel for an honest and unbiased opinion about the whole thing.
"My first take is that it seems like it's total bulls***, honestly."
"If it works, it works, and if that's because of the placebo effect, that is totally cool."
That simplifies it a bit.
If you believe "cupping" works," that's great. If you don't think it works, that's great too.
