The CrossFit workout is “Grace”.
In this workout, you perform 30 Clean and Jerks for time. The weight used for men is 135 pounds and 95 pounds for women. During the Amazing “Grace” fundraiser all participants may modify the weight used in order to accommodate their physical abilities.
To compete in the workout, all participants must complete each of the following:
Beginning
The athlete begins the clean by squatting down to grasp the bar. Hands are positioned approximately a thumb’s distance from hips using what is known as a hook grip. The hook grip requires grasping the bar so that the fingers go over the thumb. This makes it much easier for the lifter to maintain his grip on the bar. The lifter’s arms are relaxed and just outside the legs with the bar up against the shins. The hips are as low as necessary to grasp the bar, with the feet placed approximately at hip width. Toes may be pointed straight ahead or angled out according to the lifters preference. The chest is up and the back is neutral to slightly hyper extended. This is the starting position of the “pull” phase of the lift.
Clean Phase
The lifter jumps the bar up through triple extension (in very quick succession) of the hips, knees and then ankles. When the legs have driven the bar as high as possible, the lifter pulls under the bar by violently shrugging (contracting) the trapezius muscles of the upper back (“traps”). This pulls the lifter under the bar and into a deep squat position. The lifter then stands (similar to a front squat) in preparation for the second phase.
Overhead Jerk Phase
From the standing position, the lifter bends the knees and then straightens them in order to propel the barbell upwards. The lifter pushes slightly with the arms. This pushes the lifter underneath the barbell. A split jerk is most often used, in which one leg lunges forward while the other moves backward. The lifter must hold the barbell overhead, keep the arms locked, and move the legs directly underneath the torso so that the entire body lines up in a single plane. A push jerk can also be used, in which the lifter keeps both legs in position, bends the knees and jumps into lockout position.
Variants
Variants of the jerk include the old style jerk where the legs stay under the lifter’s hips and the lifter squats down under the bar and then stands upright. The main advantage of the split jerk is that it is easier to balance the bar forwards and backwards whereas the main advantage of the more difficult squat jerk is a greater ease of recovery.
The power clean, a weight training exercise not used in competition, refers to any variant of the clean in which the lifter does not catch the bar in a full squat position (commonly accepted as thighs parallel to the floor or below). The hang clean, another weight training exercise, begins with the barbell off the ground arms hanging down. I.e., any position between the barbell touching the ground and the body fully erect. Both power and hang cleans are considered to be ideal for sports conditioning; as they are both total body exercises, that have been known to increase neuromuscular co-ordination and core stability.
