Whether it's during gym, or when I'm at home doing exercises I breathe like I can't and I sort of vibrate...like this... huff huff huff huff huff huff, puff puff puff puff puff puff and I move like I'm vibrating. It happens when I run, when i do sit ups, everything. is it bad? or does it mean I'm way out of shape? And I only weight 190 pounds? WTF? Any opinions?
