Basic Concepts of the Postural Restoration Institute

The human body is not symmetrical. The neurological, respiratory, circulatory, muscular and vision systems are not the same on the left side of the body as they are on the right, and vice versa. They have different responsibilities, function, position and demands on them. This system asymmetry is a good thing and an amazing design. The human body is balanced …

“Why isn’t anatomy taught this way in school?”

Each time our team teaches Immaculate Dissection, we’re asked that same question. With curricular committees setting standards, the focus at school is to satisfy requirements for professional licensure. The type of practitioner a clinician or trainer will become is largely determined in practice, not in school. Although we may feel curriculum-based education falls short, we can still learn as much …

Training Athletes and Patients for Explosive Strength

Training Athletes and Patients for Explosive Strength

Since strength training was first studied as a method for preparing strength and power athletes for competition, it has been recognized that peak force takes some time to reach. And yet some athletic movements are completed in just 100 – 150ms. Therefore, the rate at which force is developed is likely at least as important for athletes as maximum strength. Training …
