I too, will wake up at 4 do my pinning

eat some oats/banana or Apple a shk wait 30min as well then pre- workout
I don't like feeling too bogged down by 530am workouts...I prefer fasted cardio but can't keep that intensity without some carbs and fats - after I'll have a big meal(8 egg whites w/veggies,spinach, meat, ch, more oats(or a bagel)a banana etcIt's key to switch things up(routine etc... But I always go at the same time... As Bio stated its much better to keep the same consistant routine & time)....
Just My exoerience!
