Every CrossFit movement has major form faults such as loss of lumbar curve in a squat or muted hips in a med-ball clean. In stone shouldering, one of the worst faults is simply not trying hard enough.
Lifting a barbell is far easier than lifting an atlas stone, and odd-object lifting has a set of rules all its own. Kurtis Bowler of Rainier CrossFit teaches how to get a heavy stone from the ground to the shoulder, then goes over the major faults of the movement.
Many athletes will set up too far away from the stone and treat the movement like a squat instead of a straight-leg deadlift, while others will ignore core-to-extremity movement in an attempt to curl the stone. Others, of course, lack the grinding determination needed to get an awkward object onto their shoulder.
During a practical session following the lecture, Bowler leads a group of athletes through a lifting session and helps them get the form right for maximum safety and efficiency.
