Congratulations mate! Seems to all be going pretty well at the moment![]()


Why? Do you HAVE to do cardio? Are they not happy with your progress or is this some medical drivel?
Are you alternating HIIT with LISS on a every other day basis? or have I misread the above as 40 minutes HIIT split around 40 minutes LISS per day.
I've never found fasted steady state cardio difficult, HIIT on the otherhand is brutal fasted, especially if your carb macro is low.


but surely by the time you get to the 2nd HIIT session you're going to be pretty much running on empty anyway and it'll just serve to completely wipe you out without making a massive difference to kcals burnt.
I did two high days but doubled everything so it was a 4,478 for two days 
That much cardio and so little calories, I'd be surprised if it spared your muscles completely. Are you doing weights too?
