Clean and press
The clean and press is a compound weightlifting exercise performed with a barbell, beginning with the clean phase in which the bar is explosively pulled from the floor and received at the shoulders in a squat or power position, followed by the press phase in which the bar is strictly pushed overhead to full elbow extension without leg drive.[1] This movement integrates explosive hip extension, rapid triple extension of the ankles, knees, and hips, and upper-body pressing strength, engaging the posterior chain, core, quadriceps, and shoulders in a coordinated full-body effort.[2] From 1928 to 1972, the clean and press constituted one of three core lifts in Olympic weightlifting competitions, alongside the snatch and clean and jerk, standardizing the sport's format during that era.[3][2] It was discontinued as an Olympic event after the 1972 Games primarily due to escalating difficulties in refereeing proper form, as lifters increasingly employed excessive spinal arching and layback techniques that blurred the line between legitimate pressing and impermissible momentum assistance, undermining objective adjudication.[4] Despite its removal from formal competition, the clean and press remains valued in strength training programs for fostering power output, neuromuscular efficiency, and overhead strength, with historical benchmarks including Vasily Alekseyev's 236.5 kg world record set in 1972, reflecting peak human capability in the lift under pre-discontinuation rules.[5]Overview
Definition and mechanics
The clean and press is a compound barbell exercise that integrates explosive pulling and catching mechanics in its initial phase with strict overhead pressing in the subsequent phase. In the clean, the lifter pulls the barbell from the floor using a hip-dominant extension, accelerating it upward before dropping into a partial squat to catch it at shoulder height in the front rack position, with the bar resting on the deltoids and clavicles while elbows are held high.[6] [1] This phase emphasizes rapid force production through triple extension of the lower body joints.[7] The press phase follows immediately without regripping or repositioning, requiring the lifter to extend the arms overhead to lockout while maintaining locked knees, ankles, and hips to prevent any leg drive assistance.[6] [8] This strict form, as mandated in Olympic rules until its removal in 1972, tests upper body pressing strength, core stability, and shoulder mobility, with the bar path typically arching slightly forward due to lumbar extension for mechanical advantage.[8] The exercise as a whole demands sequential muscle activation across the kinetic chain, fostering coordination between lower body power generation and upper body force application.[7]Primary muscles targeted
The clean phase of the exercise primarily recruits the gluteus maximus, hamstrings, quadriceps, and erector spinae for the explosive hip extension and pull from the floor, alongside the trapezius and latissimus dorsi for shrugging and stabilizing the barbell during the catch.[9][10] These muscles generate the triple extension at the ankles, knees, and hips necessary to accelerate the barbell upward, with electromyographic studies on similar power cleans confirming high activation in the vastus lateralis and gluteus maximus during the second pull.[11] In the press phase, the anterior and medial deltoids, triceps brachii, and upper pectoralis major serve as primary movers to extend the elbows and elevate the bar overhead from the front rack position, while the trapezius and serratus anterior provide scapular stabilization.[12][9] Core muscles, including the rectus abdominis and obliques, engage throughout both phases for trunk rigidity and force transfer, as evidenced by higher oblique and lumbar multifidus activity in variations of the clean and jerk.[13] Overall, the compound nature demands synergistic activation across these groups, prioritizing posterior chain power and shoulder girdle strength over isolated hypertrophy.[10]Technique
Clean phase breakdown
The clean phase transitions the barbell from the floor to a front rack position on the shoulders, enabling the subsequent press, and is executed in a continuous motion emphasizing explosive power and precise bar path control.[14] This phase mirrors the clean in Olympic weightlifting's clean and jerk but concludes without an overhead jerk, often employing a full squat clean to handle heavier loads as seen in historical competitions.[15] Starting PositionThe lifter positions the barbell over the mid-foot with shins touching the bar, feet hip-width apart, and weight balanced across the entire foot for stability. Hips are set higher than knees, shoulders aligned slightly ahead of or over the bar, and the back maintained in a neutral arch with arms straight and elbows rotated inward to establish tension. This setup ensures a strong base and prevents early momentum loss, with common faults including insufficient back tension or shoulders too far forward, which can cause bar drift.[14][15] First Pull
From the floor to roughly knee height or mid-thigh, the bar is lifted primarily with leg drive, keeping it close to the shins and thighs while preserving the initial back angle and torso position. Pressure shifts subtly rearward toward the mid-foot as knees move back under the bar, avoiding heel dominance or excessive speed that could disrupt balance. This controlled phase builds acceleration without premature hip rise, with errors like bar separation from the body leading to inefficient power transfer.[14][15] Second Pull
As the bar passes the knees, an explosive extension of the knees and hips propels it upward, with knees driving forward under the bar before full hip thrust to maintain proximity and vertical path. The whole foot pushes against the ground, heels may lift naturally, and the bar brushes the thighs or hips at peak extension, generating maximal velocity through triple extension of ankles, knees, and hips. Faults such as hip-dominant initiation or incomplete extension reduce bar height and speed.[14][15] Third Pull
During the bar's brief weightless phase post-extension, the lifter actively pulls the body under it by elevating and rotating elbows upward and outward, transitioning from hook grip to rack while feet split or adjust to a squat stance. This turnover ensures the bar remains close to the torso, completing as the feet land, to facilitate a secure catch; delays here often result from passive dropping rather than dynamic pulling.[14][15] Receiving Position
The lifter descends into a front squat with elbows high, shoulders shrugged and locked to secure the bar in the rack against the deltoids and clavicles, minimizing forward lean or instability. The squat depth allows recovery to standing, bracing the core to utilize elastic rebound if present, with errors like incomplete depth or loose elbows compromising the press setup.[14][15]
