Back Extensors

All kinds of advice exist for preventing back pain and injury. The medical research literature offers the Beiring-Sorensen fatigue test as one specific test that assesses back extensor strength. Following the workout today (Front Squats in 10/8/6/4/2/4/6/8/10 fashion), the class received introductory instruction in this test from Carl DeRosa, the Strong Medicine Science Officer. Carl holds a couple of doctorate degrees, teaches in the physical therapy program at Northern Arizona University, has authored medical texts, presented internationally to therapists and physicians and is an all around super guy. Here's some pics of the test introduction using the Glut-Ham Bench for testing. Stay tuned for the test results (to be conducted next week) as well as analysis on how it compares to population norms.
