Why do I feel sleepy when I work out?

Question

Hi, every time that I work out and I'm in the middle of a sport activity I start to feel like I want to go to sleep.

Running or doing mountain Bike is the most common, and the funny thing is that I'm not even tired I feel like I could run 20 miles if I want to, but IDK what to do with my sleepy feeling.

I just start to have a daily vitamin complex to see if that help.

Any Idea what is going on?..... if is something else?

Answer 1

vitamins dont give you energy or lasting

just skip the sexual feelings if you do and you will be stronger after a week

and you shoud stop masturbation if you do it

try using carbohydrate powders and you will last more than you do now

Answer 2

Well, I would say that you don't have any "fuel"  for the fire.  You need to eat a mix of protein and carbs before working out.  That'll give you that boost when you are feeling slow.  I usually eat a bowl of oatmeal before working out, with a couple of cups of black coffee and Size On supplement.  I don't have any problems finishing my workouts.  Try this or maybe just a protein drink and an apple.
