I wake up everyday at 6:00 to do my HIIT program. Should I drink my whey protein shake before or after my morning workout?
Have your shake after your workout. Always best to perform cardio on an empty stomach. If you were also weight training at this time then it would be advisable to have a shake and some carbs when you wake up, however, for a cardio only session, it’s best to perform your session on an empty stomach.
