Quote from Mechanical Low Back Pain: Perspectives in Functional Anatomy by Porterfield and DeRosa, 2nd Edition, page 17: "Tissues of the musculoskeletal system have a common denominator: they all require the stimulus of nondestructive stresses to maintain their health. Nondestructive stresses refer to those forces of movement, weight-bearing and muscle contraction that load the musculoskeletal tissues within their physiologic limits."
30 Clean and Jerks for time.
CrossFit:
Men: 60Kgs
Women: 40Kgs
S&M:
First and foremost, concentrate on perfecting your form with 60 C&J's with empty bar (not for time), making sure your movements are full range and proper form. If you can do that, then
Men: empty bar to 40Kgs
Women: empty bar to 25Kgs
Post your time and any scaling/mods.
