Lots of bodybuilders take a nitric-oxide precursor supplement to get a bigger pump during workouts. The supplements contain such compounds as arginine or glycine propionyl-L-carnitine, which help the body produce NO, which in turn dilates blood vessels.
Could chocolate do the same thing? A recent study revealed that dark chocolate helps regulate blood pressure by improving blood flow. Its flavonol content may be the reason. Sugar is also a known vasodilator, as is alcohol. A preworkout wine and dark-chocolate pop, though, may be an idea ahead of its time. Try the chocolate by itself. You don’t want to compromise your balance on squat or bench day.
