Bush exercise is Four Minute Workout is a new concept of exercise that revolves around the body's ability to use Nitric Oxide for muscle growth.
It is a new version of high-intensity interval training (HIIT) that is designed to stimulate the release of nitric oxide, which can catalyze and promote health.
Nitric oxide is a molecule found in the inner layer of your blood vessels, the endothelium. It acts as a messenger molecule that transmits signals to cells in various parts of your body such as the cardiovascular, nervous and immune systems. Once released through exercise, nitric oxide works its way into the smooth muscles and causes them to relax.
The Nitric Oxide Dump uses simple movements done in quick succession, providing benefits similar to longer workouts, but accomplished in just a very small fraction of the time. Bush calls it one of the best ways to start toning your body's systems.
The Nitric Oxide Dump only takes a small amount of your time, with one session lasting between three to four minutes. Since it’s ideally repeated three times a day, you’ll be using a total of around 15 minutes.
Plus, this workout does not require the use of any dumbbells or other fancy equipment — all you need is a comfortable place to exercise and you’re good to go. In short, it’s a very economical way of achieving a healthier body.
