We all know to drive your car faster, we press on the accelerator, which provides more fuel for the engine and we accelerate. In the human body, increases in circulation naturally brings greater amounts of nutrients (fuel) and oxygen to working muscles, while also providing greater waste disposal, including the lactic acid removal (you know, the burning pain we all get when he hit the gym, run or ride).
The combined effects of greater circulation leads to vast improvements in muscle strength and power, while reducing muscle soreness. This results in us being able to train harder, perform better, while reducing the muscle soreness that halts our training in its tracks. There is a chemical that resides within our blood vesicles which allow the wall of the blood vessels to relax and thus increases the circulation. This amazing chemical is known as nitric oxide.
