Equally, there’s no getting around the importance of dusting yourself off and trying again when you hit stumbling blocks. "Getting back into the swing of it after a holiday can be tough for people," Jake Hazell, F45 Farringdon’s studio manager, tells me, and yep, he’s right. In week three, just as I was hitting my stride, I went on a long weekend to Marrakech and everything went out the window (because YOLO and there’s no way I wanted to be That Girl who ruins their boyfriend’s holiday by eschewing the bread basket and leaving him to drink alone). I ditched the meal plan and broke the plan’s no-alcohol rule, and I drank a few other times later on in the challenge and ended up going more overboard than usual because of the novelty of it. While I don’t regret the fun I had (and wouldn’t have done anything differently on holiday), it was tough getting back into the #fitness mindset and annoying knowing I’d undone my progress. The key, though, is picking up where you left off and letting it go. The challenge is hard enough as it is, without the added mental anguish of regretting some fun experiences that can’t be undone.
