This is how many Brits admit to having sex at the gym

You've probably heard that sex is pretty good exercise...and you'd be right.

You can burn up to 240 calories an hour with a good sex session (that's only 20 calories if you're a five minute wonder though). But while most of you are fully aware that this is the kind of exercise you can do from the comfort of your own home, some are taking this sex/exercise thing quite literally. A surprising amount of people are having their sex in the gym. We're not sure if it's down to the fact the gyms are so busy at this time of year that people are being forced to f**k to burn some calories, or maybe it's just all that testosterone flying about, but a little extra exercise is proving surprisingly common. A survey by Ann Summers of 2,000 people found that a quarter of people had had sex at the gym - and 47% of those were women. More than 50% used their fitness centre as a hook up spot - and 1 in 10 people even carried condoms in their gym bag just in case they got lucky. A rather unsurprising 20% said they had had it off with their personal trainer - but it was actually dating apps that most people were using to get lucky. More than 80% of the people surveyed used apps at the gym to hook up with someone they liked. Amazingly in between all this prowling, messing around with apps and having sex - people were actually finding the time to work out, apparently. Nearly two thirds of female gym-goers said doing more than 30 squats a day made them better in bed - while a further 45% said lifting light 5kg weights daily gave them better orgasms (during sex, not weightlifting we presume). Ann Summers even put together a #Sexercise workout. On that note, it's time for us to sign up for a gym. Like right now.
