What does your daily diet consist of? How many calories are you eating? How long and how hard are you workouts when you workout at home (are you pushing your cardio to the maximum or are they relatively light workouts)? I know you mentioned some of the workouts you do but more information would be great.
I ask about your diet because it sounds to me like your blood glucose levels are low. When your blood glucose levels are low you become very susceptible to passing out. And if you're working out really hard and not getting enough calories everyday to replace the ones you've lost your body will start to eat itself and your blood glucose levels will drop dangerously low.
Oh, and regarding low blood sugar (glucose), did the physical you took test for hypoglycemia?
Or, as Amp said, there is always the potential of asthma. Thanks Amp, I didn't even think of that.
