Fit in my 40s: can Instagram influencers motivate me to move?

There is something powerful about seeing a squat, or a bicep curl, performed by someone whose musculature is beyond perfect

I've never much used Instagram except for looking at pictures of pitbulls, so when I met my first influencer (an interiors one rather than fitness) I, of course, had no idea of the deadly seriousness of the medium. Existing not just on likes, but on likes as a proportion of followers, he expressly forbade me from following him, on the grounds that I seemed like the kind of person who, though approving of a post, would forget to actually click like". He had me bang to rights; I didn't follow him, and all I can remember now is that his name was Richard and Instagram influencing is huge, huge business.

The top 10 fitness influencers worldwide can earn between 10,000 and 37,000 per post - astronomical figures that work on a straightforward metric: your follower count multiplied by 0.003, turned into quids.( I don't know who decided it, I just worked it out in my head). Only two of the global top 10 (Ulisses World and Simeon Panda) are men, and the women are similar only in the sense that they all have incredible muscle definition.
