I don’t consider myself a crazy lifter but even with my basic leg routine – squats, romanians, curls and extensions, I leave the gym feeling sick on leg day. What gives?
Legs are the biggest muscle group we have. In order to fill them up with blood, that blood has to come from somewhere else and that means up top. It takes a lot of blood to fill up the leg area, it takes so much that it can literally make your nauseous. I usually feel nauseous after every leg workout. Do not be afraid of it, you will get past it. It usually takes about a month of two for you to become accustomed to it, but it will never fully go away. It is also a matter of food. With hard leg training, you are burning through your energy stores (glycogen) faster, so your blood sugar can get low rather fast. I get lightheaded no matter what I am eating, so I always try to make sureI have enough fuel in the tank to make it a bit easier. You might try eating a bit more complex carbohydrates the day before training legs to see if that helps.
