I go first thing - around 7 and it's mostly strength training.
I have a pt session once a week and today I felt properly dizzy and had to stop. Not the first time I've felt off tbh.
I have always done fasted exercise previously but it used to be more cardio based. I do feel sick if I eat too much though.
So far I have tried I slice toast and peanut butter (felt very very sick) and half a banana (less sick but banana burps!).
Only has to be small, just enough to give me enough to boost. And veggie pls.
