If you exercise first thing in the morning before having your first proper meal, what do you take/eat to fuel your workout without making you sick?
I've realised with my schedule, I need to work out soon after waking at 6am. I don't want to wake up earlier than that, and I need to be ready for work at 8.45 so don't have time for a proper breakfast to digest. Would a pre-workout supplement or a smoothie etc help with giving me energy for a HIT circuit?
