@3MoreReps oh! How strange. It was during the pandemic. You would play the song and repeat movements while it was sung « up » or « down ». Did it with squats, push-ups and V-sits. Well… I could only finish the squats challenge 🤣
I think I saw firemen do it with pull-up, on Facebook or so 😱

@3MoreReps I did it on Facebook. But people probably did it on Instagram too. Those were not live. More like: capture yourself doing it and post.
