This Danish chain has come up with the perfect antidote for your fitness fatigue: naked CrossFit (a mix of weightlifting, rope climbing and, err, tyre flipping).The idea of naked CrossFit originally started off as an April Fool’s prank when the owners of Danish gym, Spartan Mentality, mocked up an ad for the exercise class featuring very buff men in their birthday suits.Owner Steffen Haldrup Andersen said of the joke ad: ‘People are already so scantily-clad at CrossFit that we thought we might as well throw the rest away.’But, when the spoof ad went viral and men kept turning up wanting to workout in the nude, the duo began to take it a little more seriously.They soon launched naked classes every Sunday and signed up 12 eager male members on day one (no women – we presume they want to observe a few classes first).Sadly, for those wishing to get involved in some naked rope climbing, due to intense media coverage and a number of complaints, the classes only ran for a short time before they were cancelled.Shame. By the look of all those toned six packs and bulging biceps, it was definitely a great workout.(metro.co.uk)Bakudaily.az
