Lightheaded on leg days

[spittin' 'n cussin']

im getting back into doing legs and today was my third week back doing them and the 10th rep of my second working set was hell. i pushed it out all the way and got an instant headache like in the back of my neck closer to my head. the two weeks before this i have felt like passing out and not even into my workout very much. just wondering if any of you have experienced the same thing. i ate a cup of oats and 25g protein about 20-30 mins before i got there so i didnt go in the gym fasting. is there something i should take to increase blood flow or something like that? anyway thanks for the help

1) make sure you are breathing correctly

2) depending on the weight i get the same thing. Legs are the biggest muscle which makes them the toughtest. Why do you think most people neglect them.

If aren't doing any cardio, start!!! Training legs draws a lot of blood into them and away from your torso and head. The better your cardio the less you will feel like fainting/feeling dizzy.
