The average gym junkie today is all about appearance, not ability. Flash, not function. These men may have big, artificially pumped up limbs, but all that the size is in the muscle tissue; theirtendons and joints are weak . Ask the average muscleman to do a deep one-leg squat-ass-to-floor-style-and his knee ligaments would probably snap in two. What strength most bodybuilders do have, they cannot use in a coordinated way; if you asked them to walk on their hands they'd fall flat on their faces.
