Ooer! What were they of, perchance? Making snake venom cocktails? Leaping off tall buildings?
The post was intended to spark motivation, asking its fans: 'Are you getting out for a run, walk or cycle today? It’s a great day to burn off those Christmas calories… post your pics here!'
A stream of responses followed, with some claiming it's 'damaging' to encourage the mentality of burning off calories after eating - but others pointing out it would be strange for a health magazine to not promote working out.
But clearly, there are people out there who feel they should be listened to. Are they doctors, and nutritionisst? Well, no...
Complaining about the original tweet, consultant psychiatrist Dr Sarah Vohra wrote: 'Hugely concerning and problematic language. We shouldn't be ascribing moral labels to food and exercise or encouraging people to adopt an earn and burn mentality.
'It's the fall out from these damaging marketing campaigns that I see only too well in clinic.
'As a mainstream fitness magazine, why not use the opportunity to promote the positive mental and physical health benefits to be gained from doing outdoors/ exercise; improved mood, better sleep, more energy etc. Disappointing.'
Another commented: 'Posts like this are why I have been suffering from an eating disorder for over three years.
'This honestly makes me so angry, targeting young women to make them feel guilty for enjoying themselves over Christmas.'
I'm pretty sure the article's got nothing to do with your troubles...
