I've just been reading a book called the Hiit Bible and it has various workouts/exercises/challenges- I thought I'd do a 14 day hiit challenge before I go on holiday. Anyone fancy doing it with me and tracking on this thread for a bit of moral support and encouragement? You could do any Hiit workout you like (Jillian, YouTube workouts, treadmill/bike intervals etc)
I already run a fair bit, and do a circuits class once or twice a week, but I like the idea of a short sharp 20 mins shock each day. I will do my measurements later, and maybe even a pre-challenge selfie to compare with afterwards!
