For those of you that enjoy the HIIT sessions at SpinStream, sure, the 10 week Challenge has ended at the studio, but that doesn’t mean we wont still be doing a HIIT/Drills session, at least once every week. Yesterday, we gave you a taster of this with the new 6 x 5 session https://spinstream.co.uk/classes/20210108-c21-taster and tomorrow, it’ll be the all new Challenge ’21 that’s going to take us into week 21 of 2021. The 7 x 5 will be upon us and as always, it’s a session for everyone to take part in, start the challenge by giving it your very best and see how YOU can improve week on week
