Medicine Ball Clean
The medicine ball clean builds on the set up and movement pattern of the Sumo Deadlift High Pull adding a pull under the object.
1. TEACHING THE MOVEMENT
SETUP:
-
Stance = shoulder width or slightly wider
-
Weight in heels
-
Back arched/lumbar curve locked in
-
Shoulders over the ball
-
Ball on the floor between the legs with clearance for
the arms
-
Arms straight, palms on outside of the ball; fingertips pointing down
-
EXECUTION:
-
Accelerate through the heels from the ground to full
extension of the hips and legs
-
Shrug, with straight arms
-

beneath the ball
-
Stand to full extension with ball in the rack position to
complete the movement

2. SEEING THE MOVEMENT
PRIMARY POINTS OF PERFORMANCE:

Hips reach full extension
-
Hip is extended and shrug is initiated before arms pull
-
The ball is caught in a low (below parallel) and tight (not collapsed) front squat position
-
Fast and aggressive throughout

Clean and Jerk
Preparation
Stand over barbell with balls of feet positioned under bar slightly wider apart than hip width. Squat down and grip bar with overhand grip slightly wider than shoulder width. Position shoulders over bar with back arched tightly. Arms are straight with elbows pointed along bar.
Execution (Clean)
Pull bar up off floor by extending hips and knees. As bar reaches knees, vigorously raise shoulders while keeping barbell close to thighs. When barbell passes mid-thigh, allow it to contact thighs. Jump upward extending body. Shrug shoulders and pull barbell upward with arms, allowing elbows to flex out to sides, keeping bar close to body. Aggressively pull body under bar, rotating elbows around bar. Catch bar on shoulders while moving into squat position. Hitting bottom of squat, stand up immediately.
Execution (Jerk)
Adjust grip if necessary. Inhale and position chest high with torso tight. Keeping pressure on heels, dip body by bending knees and ankles slightly. Explosively drive upward with legs, driving barbell up off shoulders. Drop body downward and split one foot forward and other backward as fast as possible, while vigorously extending arms over head.
The split position places front shin vertical to floor with front foot flat on floor. The rear knee is slightly bent with rear foot positioned on toes. The bar should be positioned directly over ears at arm's length with back straight.
Push up with both legs. Position feet side by side by bringing front foot back part way and then rear foot forward.
Return
Lower barbell to shoulders, then bend knees slightly and lower barbell to mid-thigh position. Slowly lower bar with taut lower back and trunk close to vertical. The advanced athlete may unload (drop) bar from completed position. This technique may be practiced to reduce stress or fatigue involved in lowering bar as prescribed. Use rubber weightlifting plates on weightlifting platform if this unloading method is used (unless floor demolition is desired). Also known as Squat Clean and Jerk.
Once the athlete has mastered the medicine ball clean and the jerk as a single unit, then the athlete can move onto the Olympic Lift: Clean and Jerk.
Snatch
Preparation
Stand over barbell with balls of feet positioned under bar hip width or slightly wider than hip width apart. Squat down and grip bar with very wide overhand grip. Position shoulders over bar with back arched tightly. Arms are straight with elbows pointed along bar.
Execution
Pull bar up off floor by extending hips and knees. As bar reaches knees, back stays arched and maintains same angle to floor as in starting position. When barbell passes knees, vigorously raise shoulders while keeping bar as close to legs as possible. When bar passes upper thighs, allow it to contact thighs. Jump upward extending body. Shrug shoulders and pull barbell upward with arms, allowing elbows to pull up to sides, keeping them over bar as long as possible. Aggressively pull body under bar. Catch bar at arm's length while moving into squat position. As soon as barbell is caught on locked out arms in squat position, squat up into standing position with barbell over head.
Return
Bend knees slightly and lower barbell to mid-thigh position. Slowly lower bar with taut lower back and trunk close to vertical. The advanced athlete may unload (drop) bar from completed position. This technique may be practiced to reduce stress or fatigue involved in lowering bar as prescribed. Use rubber weightlifting plates on weightlifting platform if this unloading method is used (unless floor demolition is desired).
