Hardest FB Workout?

What is the hardest FB workout you’ve done?

For me it might be When I Say Jump (https://youtu.be/j3cRRCTREu0) which I did on Friday

or maybe this HIIT Like A Girl (https://youtu.be/GzvAC-9MawU) which I haven’t done since the summer but still remember the burn!

In general the worst for me are the solid HIIT routines - when there’s a mix of strength and HIIT intervals I have a much easier time getting through it!
