One woman learnt the hard way why you should never work out after having a fake tan.
Twitter user "Eve" revealed she was left branded with the Adidas logo from hitting the gym too soon after applying the fake tan.
"That's the last time a work out with tan on," she wrote along with a photo of her leg emblazoned with the activewear branding.
But it turns out Eve isn't the only one to make this tanning error.
