I do this one, only found her a few weeks ago. The first time I was sweating and thinking how long left after 10 mins - you are pretty shattered at the end and would say this is the toughest of any I've been doing this past year.

Outside is nice though, been cycling today and did a run yesterday. The HIIT routines are better for total body and building muscle, I highly recommend!

sounds like a challenge 💪

Feel free! Let me know how you get on :D
