I've lived something of a double life over the last 4 or so weeks. By all appearances, I've ducked out to the gym at lunch as I sometimes do. But that's not entirely true. I've actually been hitting the treadmill wearing a semi-airtight wetsuit attached to a series of tubes forcing positive and negative air pressure around my stomach and love handles. This is Hypoxi weight loss and it actually works. This is my sweaty story.
