Do you have to do the workouts so early in the morning though? I'm guessing it can be done at a different time so that anyone can do it?
Not sure, you'll have to look it up really.
It's just 'easier' to do it in the morning, as that's a normal working day routine...I mean you can do it at 3pm if you do late shifts for instance, but naturally you'd have to move your day around.
I've always wondered if it's worth just 'fasting' until 12, then train as I normally do at 5pm, but only eat in between 12 and 8pm....Not sure if that'd actually do anything, but might be worth a tinkle one day.
