While polarising videos like these might not be entirely accurate, they do succeed at one thing very well: getting more views.

“I think that these kinds of videos get more engagement from social media. It’s worrying because a lot of this content is designed to get the person who posted them more likes rather than actually help those who need it,” says personal trainer Sam Hall. “If you are a recreational gym goer trying to get a stronger bum, the most important thing is to remember the basics. Be consistent, use progressive overload principles and over time you will get great results. Be patient.”

When it comes to taking any kind of advice from TikTok, the most important thing to do is to check the credentials of the person that has made the video. Instead of assuming that they know better than you just because they’re making videos and publishing them online, find out how qualified they are to be giving advice.

“Be wary of fitness trends you see on social media that promise you results in unrealistic time frames,” says Ward. “It really is simple: if you want to achieve your goals and maintain them – which is just as hard, if not harder than reaching them in the first place – then you need to work hard, have discipline and be patient.”
