Ok, here's my logic, let me know what you guys think:
Peripheral circulation into adipose tissues is really poor. Taking a big hit of niacin relaxes blood vessels, causing a greater blood flow to these areas, ultimately causing "the niacin flush". Knowing this, do would you think doing cardio while flushing out on Niacin could enhance fat-burning (especially in trouble areas)?
I understand that I will look like a complete fool when performing cardio while on a flush.
