Power Clean Exercise Data Main Muscle Worked: Shoulders Other Muscles Worked: Triceps, Middle Back, Lower Back, Traps, Forearms, Quadriceps, Hamstrings, Calves, Shoulders, Glutes Push Press Exercise Data Main Muscle Worked: Shoulders Other Muscles Worked: Triceps, Upper Chest Traps ,Core , Quadriceps Equipment: Barbell Note - The top of the movement uses mostly triceps Why Do We Power Clean ? As one of the most popular lifts for improving total body power, strength and conditioning coaches prescribe the power clean for those sports whose primary movements closely mimic the mechanics of the exercise (football, basketball, volleyball) and often those that do not (baseball, distance running). The research has proven the obvious benefits of the exercise and it's carry over into athletic movement: 1. We know that the Olympic style movements are physiologically the most powerful movements man can perform. To move hundreds of pounds that far and that fast, is remarkable considering the lower power output of movements with significantly more weight. 2. The erectors (low back), glutes, hamstrings and quadriceps work together (assuming the lift is performed from the ground) in much the same way as many triple-extension movements such as vertical jumping, firing off of the line or tackling in football, and many basketball and volleyball movements. This same action can occur horizontally as well. 3. There appears to be a correlation in regards to the power clean or pulls and vertical jumping, horizontal jumping and sprint speed. As performance (amount of weight lifted) improves in the clean, improvements in jumping and sprinting speed also occur. Likewise, and I can attest to this in my own experiences, those with superior power clean poundage's tend to have the better jumps and sprints. Push Press – The Overhead Lifts Introduction Learning the progression of lifts that moves from the shoulder press, to the push press, to the push jerk has long been a staple of the CrossFit regimen. This progression offers the opportunity to acquire some essential motor recruitment patterns found in sport and life (functionality) while greatly improving strength in the “power zone” and upper body. In terms of power zone and functional recruitment patterns, the push press and push jerk have no peer among the other presses like the “king” of upper body lifts, the bench press. As the athlete moves from shoulder press, to push press, to push jerk, the importance of core to extremity muscle recruitment is learned and reinforced. This concept alone would justify the practice and training of these lifts. Core to extremity muscular recruitment is foundational to the effective and efficient performance of athletic movement. The most common errors in punching, jumping, throwing, and a multitude of other athletic movements typically express themselves as a violation of this concept. Because good athletic movement begins at the core and radiates to the extremities, core strength is absolutely essential to athletic success. The region of the body from which these movements emanate, the core, is often referred to as the “power zone.” The muscle groups comprising the “power zone” include the hip flexors, hip extensors (glutes and hams), spinal erectors, and quadriceps. These lifts are enormous aids to developing the power zone. Additionally, the advanced elements of the progression, the push press and jerk, train for and develop power and speed. Power and speed are “king” in sport performance. Coupling force with velocity is the very essence of power and speed. Some of our favorite and most developmental lifts lack this quality. The push press and jerk are performed explosively – that is the hallmark of speed and power training. Finally, mastering this progression gives ideal opportunity to detect and eliminate a postural/mechanical fault that plagues more athletes than not – the pelvis “chasing” the leg during hip flexion. (See article) This fault needs to be searched out and destroyed. The push press performed under great stress is the perfect tool to conjure up this performance wrecker so it can be eliminated. Mechanics 1. The Shoulder Press a. Set-up: Take bar from supports or clean to racked position. The bar sits on the shoulders with the grip slightly wider than shoulder width. The elbows are below and in front of bar. Stance is approximately shoulder width. Head is tilted slightly back allowing bar to pass. b. Press: Press the bar to a position directly overhead. 2. The Push Press a. Set-up: The set-up is the same as the shoulder press. b. Dip: Initiate the dip by bending the hips and knees while keeping the torso upright. The dip will be between 1/5 and 1/4 of a squat in depth. c. Drive: With no pause at the bottom of the dip, the hips and legs are forcefully extended. d. Press: As the hips and legs complete extension the shoulders and arms forcefully press the bar overhead until the arms are fully extended. 3. The Push Jerk: a. Set-up: The set-up is the same as for the shoulder press and push press. b. Dip: The dip is identical to the push press c. Drive: The drive is identical to the push press d. Press and Dip: This time instead of just pressing, you press and dip a second time simultaneously, catching the bar in a partial squat with the arms fully extended overhead. e. Finish: Stand or squat to fully erect with bar directly overhead identical to terminal position in push press and shoulder press. The Role of the Abs in the Overhead Lifts Athletically, the abdominals’ primary role is midline stabilization, not trunk flexion. They are critical to swimming, running, cycling, and jumping, but never is their stabilizing role more critical than when attempting to drive loads overhead, and, of course, the heavier the load the more critical the abs’ role becomes. We train our athletes to think of every exercise as an ab exercise but in the overhead lifts it’s absolutely essential to do so. It is easy to see when an athlete is not sufficiently engaging the abs in an overhead press – the body arches so as to push the hips, pelvis, and stomach ahead of the bar. Constant vigilance is required of every lifter to prevent and correct this postural deformation. Summary From shoulder press to push jerk the movements become increasingly more athletic, functional, and suited to heavier loads. The progression also increasingly relies on the power zone. In the shoulder press the power zone is used for stabilization only. In the push press the power zone provides not only stability, but also the primary impetus in both the dip and drive. In the push jerk the power zone is called on for the dip, drive, second dip, and squat. The role of the hip is increased in each exercise. With the push press you will be able to drive overhead as much as 30% more weight than with the shoulder press. The push jerk will allow you to drive as much as 30% more overhead than you would with the push press. In effect the hip is increasingly recruited through the progression of lifts to assist the arms and shoulders in raising loads overhead. After mastering the push jerk you will find that it will unconsciously displace the push press as your method of choice when going overhead. The second dip on the push jerk will become lower and lower as you both master the technique and increase the load. At some point in your development, the loads will become so substantial that the upper body cannot contribute but a fraction to the movement at which point the catch becomes very low and an increasing amount of the lift is accomplished by the overhead squat. Desmond Mason NBA Basketball player former high jumper Wilson's jumping program has two primary elements, both of which focus on quickness and strength. The first part of the workout consists of complicated Olympic-style weightlifting moves like the push press and hang clean (see workout), which combine traditional strengthening exercises with plyometric-like moves. Then it's all about the plyometrics themselves. |
