    Why do I passed out when do any type heavy lifting?

    It has never occurred to me until the last couple of weeks when I was doing curls with dumb bells and I passed out. Ever since this incident, whenever I do any heavy lifting or exercise that involve holding my breath between 1-10 seconds I felt dizzy and with the feeling that I'm going to pass out again. I am also not able to bend my head down long either. If I do, I also feel light headed.
