“…the laws of chance dictate that some people with berries are going to get under the bar. Many if not most of them are going to hold their breath. When they do, blood pressure will shoot up, increasing the intravascular stress on the aneurysm. Doesn’t the Valsalva pose a clear and present danger to them?…The first approach is to consider the dynamics of aneurysmal rupture in the setting of resistance training with Valsalva—the physiological evidence. The second approach is to survey the epidemiologic data—the clinical experience of what actually happens to human populations when they lift under Valsalva. We will consider each in turn.”
