I am 24, 5'8 and 185. So i have been training with my trainer since March 1st. 3 days a week 30 min sessions. It's only been two weeks but I feel like durning our workouts I get so dizzy and sometimes nausea and light headed. We waste no time between different work outs going straight to the next exercise and usually do 3 sets of 15 reps of everything. I have let myself get out of shape recently but I just dont ever remember getting so dizzy durning a work out back when I was in good shape.. Sometimes I do feel like I have to keep reminding myself to breath properly while lifting and its frustrating me because sometimes I have to cut out workouts short not because my muscles are too tired but because I am so light headed and dizzy I feel like I am going to pass out. What could this be from and how can I help this to not happen? Thanks
