If I was training for a longer period of time, I would have a different route. I used to be a supplement monger but I have eased up on thier use because sometimes it gets a bit much.
What is the primary nutrient that is converted into Glycogen by the liver? CARBOHYDRATES!!!
I never said I was a carb freak and hated protein, I know my posts are long but did you READ them?
Arioch, you are screaming. Ok, so what happens when your blood sugar crashes after the big spike from the orange juice? [probably about 15 minutes into your workout] And again, you run out of glycogen stores in 20 minutes. Do you then stop?
Why not have something that enables your energy more efficiently and more steady, like a sugar free protein drink or some cheese before you work out? Honestly, you will find that your energy for working out is much higher.
