not sure if i spelled that right, but i have a question about becoming lightheaded during training. it only happens on my leg days btw. my routine today (as usual) i woke up, drank some gaspari superpump 250, waiting 30 minutes, drank some wheyprotein 1scoop, and ate a "breakfast cookie" from quaker oats, 170 cal, 34g carbs, i waited another 20 minutes and then went to the gym, did squats, one legged squats (forgot what they called something hungarian maybe?) then calf raises and then some leg presses, at something like 70 percent of my max. then i did 15 minutes of hiit on the stair master, but i was feeling a lil light headed in the middle of my squats in the begining.. i just keep going cuz its normal for me to feel like that, and by the time i was walking home after the cardio i feel nigh throwing up status. which obviously cant be good. and i was wondering where im going wrong. am i just in real bad cardio shape? or am i not eating enough or waiting long enough after eating some carbs before hitting the gym? thanks.
