The 31-year-old Big Bang Theory star took to Instagram on Wednesday to share a photo of her bare back with the giant red circle marks created by cupping.
“Hurts so good #nofilter #cupping #horsegirltanlines,” she captioned the shot.
In the pic, Cuoco has very tan shoulders that appear to come from wearing a tank top and is showing off her large moth tattoo. She got the ink to cover up her wedding date tattoo after her split from ex Ryan Sweeting.
Cupping is a popular trend amongst celebrities. It is an ancient form of alternative medicine used to alleviate pain, stress, and inflammation, which Cuoco might acquire from her regular horseback riding.
