An upmarket London gym has been slammed after suggesting that people suffering from coronavirus have 'failed to take care of their health in the past'.

The London Bridge branch of the celebrity-loved chain F45 was branded 'disrespectful' and 'gross' on Twitter after trainee lawyer Jasmine Alexander shared a screenshot of of a post written in its members Facebook group on 15th March.

'I think it's safe to say that those of you who have made the decision to get fit and improve your health have put yourself in a great position to fight off the virus or any others than come your way in future' it read.

'This current pandemic has already proved to be causing the greatest damage to those that have not prioritised their health in the past and therefore exposing themselves and putting themselves in a high risk category.'

The post added that the gym has taken 'appropriate measures' to ensure customers are not at risk of infection, but didn't say what they are.

It continued that 'using your lungs and being active is a great way to fight this respiratory disease.'

'Maybe now is the time to take positives from this situation and encourage our friends and family to also engage in some type of exercise to put them in the same position as many of you are in, in which good health is crucial.

'Please let them know we have a tailored 28 day programme with full guidance and support for anyone unsure on how to get started.'

The Australian gym chain is endorsed by celebrities including Mark Wahlberg and runs popular eight-week fitness challenges that promise to transform your physique at a cost of £460.

Femail has contacted F45 for comment.

Jasmine claimed in a later post that she was removed from the group for criticising the post.

Boris Johnson last night urged everyone in the country to stop all 'non-essential' contact with others - which includes avoiding the leisure industry.

At a dramatic press conference, the PM warned that the coronavirus was now in a phase of rapid spread across the UK, with London seeing a particular surge, and it was time to take radical action to stop the NHS being swamped.

Everyone should avoid contact that is not absolutely necessary - with restaurants, bars and cinemas and travel off limits, and an end to large gatherings. Admitting that the squeeze could last 12 weeks or even longer, Mr Johnson acknowledged he was 'asking a lot'.

Entire households should self-isolate for two weeks if one person has been showing symptoms, and older people should prepare to stay away from risks for months to come. He said that meant 'you should not go out, even to buy food or essentials'.
