"Pre Workout" you’ve tried💪🏋️‍♀️

I normally drink a cup of coffee before work out. The first reason is I do home work out in the morning.  Secondly, coffee can boost up my mind to focus the exercise.  But if someone got stomach issue, don't only drink coffee in the start of the morning.  May need to eat little food together, othwise you may get upset of you stomach.
