Barbell Clean and Jerk
What Is the Barbell Clean and Jerk?
Barbell Clean and Jerk is a compound exercise that primarily targets the quads, glutes, hamstrings, back and shoulders and also engages the triceps, calves and core. It is an advanced-level movement that requires strength, speed, coordination, and proper technique.
This exercise is one of the two competition lifts in Olympic weightlifting and involves two explosive phases: the clean, where the barbell is lifted from the floor to the front rack position, and the jerk, where the bar is driven overhead in a powerful motion. It builds full-body power, athleticism, and overall functional strength. In competition it follows the snatch, and a lifter's best successful clean and jerk is added to their best snatch to make their total.
The version shown here is the classic competition style: a squat clean, received in a full front squat, followed by a split jerk. Catching the clean above parallel turns it into a power clean, which takes less mobility but usually limits the load, while a push or power jerk replaces the split with a shallow squat catch and the feet staying side by side. The pull from the floor loads the hamstrings, glutes and back, standing up from the full squat is mostly quads and glutes, and the jerk is driven by the legs, with the shoulders and triceps finishing and holding the lockout.
The clean and jerk is widely used by athletes to improve power output, vertical jump, and explosiveness in sports that require rapid movements. It's also popular in CrossFit and strength training programs due to its complexity and high metabolic demand.
Because of its technical nature, the clean and jerk should be learned with proper coaching or supervision. Even small form errors can reduce effectiveness or increase injury risk, especially as the weight gets heavier. It’s recommended to master foundational movements like front squats, deadlifts, and overhead presses before attempting this lift, and most lifters then learn it in parts with the Barbell Hang Power Clean, Push Press and Barbell Split Jerk before joining them. Mobility in the hips, ankles, shoulders, and wrists also plays a major role in executing the clean and jerk efficiently.

Instructions
- Stand with your feet about hip-width apart and the bar over your midfoot. Squat down and grip the bar just outside your knees with an overhand hook grip, arms straight, back flat, chest up and shoulders slightly in front of the bar.
- Push the floor away with your legs to lift the bar, keeping your back angle steady and the bar close to your shins.
- Once the bar passes your knees, keep it close to your thighs and extend your hips, knees and ankles explosively, finishing with a shrug.
- Pull yourself under the bar into a full front squat, the squat clean shown here, whipping your elbows forward so the bar lands on the front of your shoulders with your elbows high.
- Stand up out of the squat to complete the clean, then reset your grip if needed and take a breath.
- Keeping your torso upright and your weight over your whole foot, dip straight down a few inches by bending your knees.
- Drive hard through your legs to launch the bar off your shoulders, then push yourself under it in a split jerk, as shown: one foot steps forward and the other steps back.
- Catch the bar overhead on locked arms, with the bar over the back of your neck, your front shin roughly vertical and your back knee slightly bent on the ball of the rear foot.
- Step the front foot back halfway, then bring the back foot forward to meet it, keeping the bar locked out overhead.
- Lower the bar to your shoulders, then to the floor under control, or drop it if you are using bumper plates on a platform.
Common Mistakes
Pulling with the arms too early
Using the arms instead of extending the hips reduces power and throws off timing.
Letting the bar drift away
Letting the bar swing out in front of the thighs during the pull sends it forward, so you have to chase it in the catch.
Catching the bar with low elbows
This places excessive stress on the wrists and can lead to instability in the front rack.
Dipping forward in the jerk
Letting the chest drop or the weight shift onto the toes in the dip drives the bar forward and makes the overhead catch unstable.
Improper footwork in the jerk
Stepping too narrow or wide during the split jerk leads to balance issues and poor lockout.
Skipping the dip and drive
Failing to use the legs in the jerk phase puts unnecessary strain on the shoulders and limits force output.
Injuries
Barbell Clean and Jerk is a medium risk exercise when performed with proper technique. It moves heavy loads fast through a deep squat and into an overhead lockout, so small errors cost more than in slower lifts. In a 2024 systematic review, weightlifters reported 2.4 to 3.3 injuries per 1000 hours of training, and the knee, lower back, shoulder and hands or fingers were the most common injury sites.
Typical strain points are the wrists and elbows in the front rack, especially with tight wrists, triceps or lats; the knees in the squat catch and the jerk dip if they cave inward; the lower back if it rounds during the pull; and the shoulders when the bar is caught overhead on soft or misaligned arms.
To prevent injury, warm up thoroughly, use bumper plates on a platform, and learn to miss: push the bar away and step out from under it rather than fighting a failed clean or jerk with bent arms or a rounded back. Build the lift in parts with the Barbell Hang Power Clean, Barbell Front Squat, Push Press and Barbell Split Jerk, then add weight to the full lift only while every rep looks the same. Beginners should start with lighter weights or even PVC pipes to learn movement mechanics before progressing to heavier loads.
Stop the set and get it checked if you feel sharp pain in a wrist, elbow, shoulder, knee or the lower back, a pop or sudden giving way in the knee, or numbness or tingling down an arm or leg.
Frequently Asked Questions
- Q: Can beginners do clean and jerk?
Beginners can learn it gradually with proper coaching, but it’s not recommended to start heavy or unsupervised.
- Q: How many reps should I do in a workout?
Most programs use low reps (1 to 3) with focus on technique and rest between sets.
- Q: Is this better than separate strength lifts?
It serves a different purpose - building explosiveness and athleticism - rather than pure hypertrophy or max strength.
- Q: What is the difference between a squat clean and a power clean?
A squat clean, the version shown here, is caught in a full front squat, while a Barbell Power Clean is caught above parallel. Because the deeper catch means the bar does not have to be pulled as high, most lifters can clean more weight with the squat version.
- Q: Should I use a split jerk or a push jerk?
The split jerk shown here is the most common style in competition, because the front-to-back stance leaves more room to save a bar that drifts forward or back. A push or power jerk keeps the feet side by side and is simpler to learn, so some lifters start there, but it is less forgiving when the bar path is off.
- Q: Can I drop the bar after the jerk?
Only with bumper plates on a lifting platform or a floor made for it. Otherwise lower the bar to your shoulders first, then down to your thighs and the floor under control.
