lately, ive been hitting legs pretty hard and i feel extremely dizzy and nauseaus during a leg workout. most of the time, i cant hold it in, and just run to the toilet to puke. i eat 1 cup oatmeal (cooked) and 2 scoops of whey isolate 1 and a half hour before my leg workout. i did 4 work sets of squats 20, 15, 12, 10 reps, then i did 2 sets of leg presses and that did it for me. im gonna g back later for leg extensions, hamstring work and calve work. can someone help me out here.
