Common Mistakes

The foot under the kettlebell is turned outward (laterally) instead of being positioned straight or turned slightly inward.

The hips are rising first in the dead clean or dead snatch.

Not creating tension between you and the kettlebell(s) before pulling.

Curling instead of pulling back to keep the weight closer during the pendulum swing, clean, or snatch.

Lowering from overhead too slowly can waste energy and turn the return into an unintended controlled eccentric. This applies when the goal is an efficient press, jerk, or snatch return. It is not a mistake when a slow eccentric or tempo lower is intentionally programmed.

The handle sits high in the palm and the wrist bends backward, breaking the line from forearm to hand at the joint. The problems cascade: the wrist joint bears load it was not designed for, the forearm muscles fight an angle they cannot win, the bell bells out, the shoulder rotates, and a shoulder problem starts in the hand.

Gripping the kettlebell handle too tight throughout the entire movement, including phases where grip tension is not needed. A death grip on the handle creates constant tension on the forearm tendons. Those tendons end at the elbow joint, so persistent over-gripping leads to elbow pain, blisters, and ripped calluses.

Wrist flexion and the downward pull of the elbow are missing when dropping from overhead in the Hardstyle snatch. When everything is loose on the drop, the weight yanks the arm forward. The shoulder takes the hit, and the back is not working at all. The drop is where the back muscles (lats, rhomboids, lower trapezius) should be engaged. A passive drop removes half the exercise.

The heels lift off the ground during the swing, clean, or snatch. The ankles bend and the knees drop forward, breaking the vertical shin angle.

The non-working arm is stiff and not moving along with the working arm.

Rotating the spine in Hardstyle ballistic exercises.

Using a weight too heavy for the task at hand.

Once the kettlebell is overhead, the head turns away from the arm that holds the kettlebell.

Using the corkscrew during grip transition either up or down or both, instead of using the door knock.

Holding on tight throughout the clean or snatch without transitioning between grip states. Every phase of the clean and snatch has its own grip: hook grip during the pull, release into ballistic flight, hand insertion at the top, catch in the rack, release on the drop, and back to hook grip. Holding on the entire time means the handle spins inside a closed fist.

Not following the progression required to safely learn an exercise and jumping in the deep end.

The neck is flexed/bent and the eyesight may be down while bringing the kettlebell overhead.

Performing a straight arm drop from overhead in the snatch. Following the weight down from overhead is the most dangerous version of the "following the kettlebell" mistake. The weight is as far from the body as it can be. If the lifter chases it forward with a straight arm as it drops, the load on the lower back is massive.

The neck flexes forward on the drop from overhead during the snatch.

The press-out happens too late in the snatch.

The shoulder is raised once the kettlebell is overhead, indicating scapula elevation instead of depression. The arm is loose, the weight is wobbling, and there is no fixation. This could be lack of strength, lack of concentration, or most commonly, lack of shoulder mobility. A telltale sign: leaning back at the top of every rep to get the weight overhead. That is the spine compensating for a shoulder that does not have the range it needs.

Breaking the dead clean up in two movements instead of one continuous pull.

The knees travel too far forward during the dip in the push press or jerk.

The stance is too wide for the squat.

Using a weight that is too light for a ballistic or power exercise. If the weight is too light, there is no resistance, and the lifter ends up moving it with the arms because it is so easy. This teaches the wrong movement pattern from day one.

Not pulling long enough in the snatch.

The upper back rounds during the squat due to weakness, lack of scapular engagement, fatigue, or using a weight too heavy.

Bumping or casting the weight away from the racking position to enter the backswing.

The torso leans forward excessively during the dead clean or dead snatch.

With the drop for the backswing for a swingclean, you want the weight to fall away from you and then back into you. As you detach the elbows early, the weight starts to fall down rather than away. The reason you want it to fall away is that you want a good, deep backswing.

The ankles and knees are not bending enough.

Flipping the kettlebell over the fist on the drop for another clean, half snatch, or other racking exercise. Instead of a controlled transition, the weight rotates over the top of the hand.

The feet leave the ground during the jerk, like a jump. This is not a barbell jerk where the feet split apart. In a kettlebell jerk, the balls of the feet stay planted. Heels can lift slightly, but the lifter is not jumping.

Squatting too deep in the dip phase of the jerk or push press.

Placing the kettlebell too far from the body for a dead clean or dead snatch.

The shoulder is loose and/or pressing starts too early in the jerk or push press. When pressing starts before the leg drive is complete, the movement becomes a press with a dip rather than a true jerk. The legs should do the work; the arms lock out while the lifter is still in the squat-under position.

The knees cave inward during a pass exercise.

Not bringing the kettlebell high enough during the assisted dead clean drill.

Not generating enough speed on each rep of a ballistic Hardstyle exercise.

When the elbow is disconnected from the hip, the force generated from the legs has to travel through the torso, shoulder, and upper arm before reaching the kettlebell. With a connected elbow, the force transfers directly from the legs through the forearm into the kettlebell.

The ankles are not bending enough.

Not fully extending the hips and knees or not standing straight at the top of the movement. The hips stay slightly bent, the knees are still soft, and the glutes never fully engage.

The chin drops to the chest or the neck flexes forward during ballistic exercises.

The kettlebell bangs the forearm during the clean. This happens for several reasons: too much power (bell goes too high and falls back down), weight too far from the body (then pulled in hard), no hand insertion (holding on while it flips), or flipping over the fist instead of guiding it around.

The kettlebell bobs or bounces at the bottom of the backswing instead of transitioning smoothly. The arms come back, hit the body, and stop abruptly, but the weight wants to keep going. The handle moves inside the hand, creating friction.

Not pulling long enough in the clean.

There is no hand insertion or the handle is not at the correct 45-degree angle when racking. When the lifter holds the handle and the bell flips over the fist, the round part slams into the forearm. This happens with cleans and snatches. Note: there is also a Hardstyle grip, but this mistake is not about that.

The thumbs point forward during a powerful or explosive clean, which is incorrect for Hardstyle and freestyle. This does not apply to Sportstyle.

The environment or set-up is limiting the natural stance required for the exercise.

The elbow flares out excessively to the side during the clean.

The weight travels inward toward the body and causes an impact on the forearm or chest during the swingclean.

The clean or snatch lacks sufficient explosiveness. If the kettlebell does not enter ballistic flight, the lifter cannot let go of it. If they cannot let go, they cannot insert the hand. So they end up muscling it up. Everything falls apart from this one mistake.

The palm of the hand is visible in the racking position, indicating incorrect forearm rotation.

The shoulders and/or eyesight are not leading the movement during the dead clean or dead snatch.

Not gripping the handle in the middle or center.

The shoulder is used to raise the weight instead of the legs and hips driving the movement. The deltoid is doing the lifting work. A diagnostic sign: the arm bends and the kettlebell droops -- it is no longer an extension of the arm.

The upper back rounds during the exercise. Hunched back, no scapula activation. The weight is pulling the lifter forward and the upper back is doing zero work. Just because the exercise is being performed does not mean the upper back is being worked -- it only works if those muscles are intentionally activated.

The backswing is too shallow.

The stance is too wide for the swing.

The weight is being pulled up with the arms instead of being driven by the hips and legs. The tell: the knees and hips are still bent and the elbow is already bending. That is curling, not cleaning.

The scapulae are not engaged or activated during the exercise. The upper back and neck strain because the scapula is not doing its job. Common causes: weakness in the upper back muscles, tightness in the chest pulling everything forward, or simply not connecting with the muscles -- the lifter does not feel the position they are in.

The elbow is disconnected from the hip in the racking position due to excess upper body tension.

Going faster than intended during a drill exercise.

The elbow is not positioned directly under the weight in the bottoms-up press.

Not gripping the handle tight enough during the bottoms-up press.

Not holding the handle in the middle during the bottoms-up press.

Not keeping the weight directly above the elbow during the floor chest press.

The arm is not fully straightened when the kettlebell is overhead.

Doing too many reps causes fatigue which transfers work from the intended muscles to other joints and compensatory patterns.

Using a weight that is too heavy causes compensation, transferring work to joints and muscles not intended for the exercise.

The strict press is intended to be performed with only the shoulder and elbow joint moving. When the weight gets heavy or fatigue sets in, the body wants to help: the legs dip (turning it into a push press), the spine leans sideways (turning it into a side press), or the hips shift. None of that is a strict press.

The ankles are not supposed to be involved in any variation of the hip hinge. A common mistake is to bend the ankles so that the shins are no longer vertical and the knees are coming forward.

The back rounds during the exercise, especially when trying to create more range than flexibility allows.

The torso traveling further toward the ground while the hips and ankles have stopped moving in squat variations.

The knees cave inward during the exercise. This is typically caused by weak or disengaged hip abduction and external rotation muscles, though the issue can also originate from the ankles and feet.

Casting or throwing the kettlebell away from the body during the drop for the backswing, rather than letting gravity initiate the descent. The weight is pushed or thrown outward instead of being allowed to fall.

Looking at the horizon in the bottom position. This is sometimes used as a cue to help keep the shoulders back, but it creates neck hyperextension.

The hips and/or knees begin hinging too early when the weight drops into the backswing, rather than staying in extension until the weight returns close to the body. The weight reaches the top and starts to fall, and the lifter follows it immediately, bending forward instead of waiting.

The lower back rounds during the bent-over row.

Initiating the row by bending the elbow and curling the weight up instead of driving the elbow back using the lats and rear deltoids.

The torso rotates excessively toward the working arm during single-arm row variations.

The pull stops short, with the elbow barely reaching the torso line. The full range of motion — where the elbow passes behind the body — is not achieved.

The shoulders elevate (shrug) toward the ears during the pulling phase.

During the renegade row, the wrist of the support arm bends or rotates outward on the kettlebell handle.

The front knee collapses inward (valgus) during the lunge, instead of tracking in line with the toes.

The step length is too short.

The torso leans forward during the overhead reverse lunge.

Stepping with the feet on the same line (like walking on a tightrope) instead of maintaining hip-width spacing between the feet.

The front heel lifts off the ground during the lunge.

The elbow disconnects from the ribcage during the racked reverse lunge.

The torso leans away from the loaded side during a single-arm farmer carry, indicating that the core is not resisting the lateral pull of the weight.

The arm bends or the shoulder drops during the overhead carry.

Taking fast, short, shuffling steps during carries.

The elbow disconnects from the ribcage during the racked carry.

Looking down at the ground or at the kettlebell during carries.

Pulling the torso straight up off the ground using the core and hip flexors, like a sit-up, instead of rolling onto the shoulder of the support arm first.

Looking away from the kettlebell during the early phases of the get-up (floor to standing), causing the arm to drift and losing awareness of the weight position overhead.

The support hand (or elbow) is placed too close to the hip during the transition from lying to seated.

Moving through the get-up positions too quickly, blending transitions together instead of pausing in each position to establish stability before moving to the next.

After the leg sweep in the Turkish get-up, the back knee is not aligned under the hip, or the front foot is not positioned to create a stable lunge-like base for standing up.

The shoulder on the loaded side elevates toward the ear instead of staying packed (depressed and retracted) throughout the get-up.

The lower back rounds (lumbar flexion) during the deadlift, especially at the bottom of the movement.

The kettlebell drifts away from the body during the deadlift.

Dropping the hips low and bending the knees excessively in a hip hinge deadlift variation, turning it into a squat movement instead of a hinge. The knees travel forward and the shins lose their vertical angle.

Leaning back excessively at the top of the deadlift, hyperextending the lumbar spine instead of finishing in a tall, neutral standing position.

The hips rotate open or the standing knee collapses during the single-leg deadlift, usually because the hip stabilizers cannot control the single-leg balance under load.

Initiating the pull with the arms and shoulders instead of driving up with the legs and hips first. The elbows bend before the hips are fully extended.

At the top of the high pull, the elbow drops below the wrist or hand level, indicating insufficient hip drive and over-reliance on the arm muscles to reach the target height.

Pulling the kettlebell higher than intended, past the chest or shoulder line, causing it to crash into the shoulder or flip over the hand. The high pull should end at approximately chest height with the elbow pulled back.

Holding the breath for the entire duration of a kettlebell hold (rack hold, overhead hold, or frontal hold).

The wrist bends (flexion or extension) during the frontal hold instead of maintaining a neutral, straight alignment with the forearm.

The kettlebell drifts away from the chest during the goblet squat, with the arms extended forward instead of keeping the weight tucked close to the body.

During the cossack squat, the torso collapses toward the squatting side instead of remaining upright, or the weight shifts unevenly because the straight leg foot lifts off the ground.

The weight shifts forward onto the toes during the squat, with the heels lifting or becoming unloaded. This indicates the center of gravity is too far forward, often due to limited ankle mobility or excessive forward lean.

Bending both knees excessively during the windmill descent, turning it into a lateral squat pattern instead of a hip hinge with thoracic rotation. The back leg should remain straight with only a soft bend in the front knee.

Treating the windmill as a side bend instead of a hip hinge with thoracic rotation. The movement becomes lateral flexion of the spine rather than pushing the hip out and rotating the thoracic spine to open the chest.

The torso rotates forward or backward during the side bend instead of moving strictly in the frontal plane (side to side).

During kettlebell push-ups (standard, crush grip, or bottoms-up), the wrists roll outward or the grip loosens on the kettlebell handles.

The elbow wings out to the side instead of staying tucked by the ribs during the rack hold.

The torso tilts laterally during the overhead hold.

The lumbar spine hyperextends to compensate for insufficient shoulder mobility.

Swinging the extended leg up and down to generate momentum for pulling the body up, instead of rolling onto the shoulder. This compensatory pattern often indicates the weight is too heavy.

Arching the lumbar spine to maintain the overhead position during the carry instead of keeping the ribs down and core braced. Common when shoulder mobility is limited.

The upper trapezius elevates the shoulder toward the ear during the overhead carry instead of keeping the shoulder packed down and back.

The torso tilts toward the loaded side during the suitcase deadlift, defeating the anti-lateral-flexion purpose of the exercise. The shoulders should remain level throughout.

The knees collapse inward (valgus) during the sumo deadlift instead of tracking over the toes. The wide stance makes knee tracking even more critical than in conventional deadlifts.

The kettlebell moves forward, backward, or sideways during the windmill instead of staying fixed in one position overhead. If it drifts forward, the deltoids are taking the load instead of the shoulder stabilizers, which can cause shoulder damage. This is often caused by not looking at the kettlebell or not engaging the stabilizers of the shoulder.

The weight shifts onto the front leg during the windmill instead of staying primarily in the back (working) leg.

During the gorilla row, the non-pulling hand is passive on the kettlebell instead of actively pressing into it.

Using maximal effort and tension on every rep instead of letting the bell ride its own momentum. Turns the pendulum into a hinge-style drive and defeats the efficiency the pattern is built for.

Keeping the knees bent at the deep backswing instead of straightening them. The hips stay low, the bell cannot swing freely underneath, and the pendulum mechanics are lost.

The kettlebell is allowed to fall ballistically into the rack position like a jerk, instead of being pulled down under control like the negative of a military press.

With two kettlebells, one arm reaches lockout before the other. The kettlebells arrive overhead at different moments instead of together.

Lifter looks up by hyperextending the neck at the bottom of the swing instead of keeping the neck neutral.

As the kettlebell travels overhead it is tempting to crank the head back or jut the chin to track it, which takes the neck out of line. Some lifters also arch the low back to get the bell overhead instead of finishing with a neutral spine.

Pushing the bell forward with the hips (what people call humping the bell) instead of pulling it out from between the legs. The kettlebell stays connected to the hips on the way up and gets pushed by them.

The kettlebell is not decelerated before it contacts the ground. Instead of a controlled placement with near-zero velocity at ground contact, the kettlebell still carries momentum when it lands. Seeing the kettlebell(s) move or wobble after being placed on the ground is a clear sign that the return was not controlled.

The non-pressing side of the body has no tension during the strict press.

The bell is put down first and only rotated afterwards. The handle should already have been rotated on the way down, ready for the next rep.

Pulling the kettlebell down on the descent using only the arms instead of the whole body, or losing the brace under the harder eccentric load.

Wrists break or bell flops instead of maintaining a straight line from shoulder through hand to bell.

Arms lose contact with the midsection at the back of the swing, creating gap between forearms and body.

Lifter keeps legs completely straight, performing a stiff-legged swing instead of allowing natural knee bend.

Shins angle forward during the backswing, turning the swing into a squat pattern instead of a hinge.

Lifter does not fully extend hips, knees, and ankles at the top of the swing.

Lifter does not adhere to the prescribed tempo count for each phase of the press.

Lifter fails to take a breath during the overhead hold phase when the tempo requires a pause.

Weight is dropped from overhead to rack with no eccentric control.

Lifter holds breath instead of maintaining a continuous breathing cycle throughout the set.

The kettlebell travels away from the body during the press instead of staying close.

Lifter bounces or uses body momentum to initiate the press instead of a clean start from rack.

Lack of full-body tension from the start of the press to lockout. Loose legs, glutes, or core.

Rib cage flares out instead of staying packed, breaking core stability.

Elbow is not fully extended at the top of the press. Arm is not stacked over shoulder.

Wrist is hyperextended under the kettlebell instead of maintaining a neutral position.

Elbows are positioned out to the sides or pushed forward instead of under the weight.

Shoulders are elevated/shrugged in the rack position before pressing.

Core is not pressurized during the movement. No intra-abdominal pressure on descent.

Lifter stops short of full extension, failing to complete the rep by aligning all joints.

Staying in the bent-over rowing position past the point where the lower back can maintain good form. The back rounds, the shoulders hunch, and reps continue in a compromised position.

Lifter relaxes and drops into the bottom position instead of maintaining active tension throughout.

Hips push back first instead of the proper sequence where hips lead going down with shoulders following.

Shoulders lead the descent instead of knees. This turns the squat into a hinge pattern, loading the lower back.

Kettlebell hangs from a white-knuckle grip instead of resting in the cradle formed by the forearm and bicep.

Standing too close, leaving no room to hike the bell back. Standing too far, forcing a reach that produces excessive hinge and loads the lower back before the first repetition.

Wrists are hyperextended under the weight of the kettlebell instead of staying neutral.

Elbows are flared out to the sides or pushed forward instead of being directly under the weight.

Upper back is loose and lats are not engaged while holding the rack position.

Applies at set up and again as the bell enters the backswing on the drop.

Shoulders are elevated/shrugged instead of being pulled down and packed.

Lifter does not fully extend hips and knees at the top of each rep.

Lumbar spine loses neutral position at the bottom of the squat — posterior pelvic tilt (butt wink), sagging, or lateral shift.

No redirect, so the bell continues travelling out and has to be chased. Redirect applied late, after the bell has already travelled out. Elbow driven forward rather than back.

Lifter does not reach parallel depth. Hip crease stays above knee line.

Handle still horizontal when the hand attempts to enter. Rotation happening after the catch instead of before it.

The transition is from hook into loose grip, the grip in racking is called Loose Grip, also Racking Grip, also Safety Racking grip (if using two bells).

Distinct from flipping the kettlebell over the fist on the drop, which has its own entry.

Elbow not fully flexed, leaving the bell held away from the body. No defined end to the repetition.

Knees collapse inward (valgus) during descent or ascent instead of tracking over the toes.

Lifter loses balance by shifting weight forward onto toes or backward onto heels during the squat.

The next repetition starts from a different position.

Kettlebell sport uses anatomical breathing: you exhale every time the body compresses, and the inhale takes care of itself as the body expands. The exhale is skipped on one or more of the compressions, or the breath is held through a part of the rep.

Lifter does not adhere to the prescribed tempo count for each phase of the squat.

Going onto the balls of the feet (lifting the heels) before finishing the push press part of the jerk. The heels come up while the knees are still bent, so the legs never fully extend in the drive.

On the way up, hips rise faster than shoulders, turning the ascent into a good-morning pattern.

Bending the knees for the jerk dip, pausing at the bottom, then driving up. The dip and drive should be one continuous motion with no stop at the bottom.

The kettlebell free-falls on the backswing instead of being actively directed between the legs. Without the insert, the weight drops too low, the back rounds, and control of the kettlebell is lost.

Lifter does not synchronize breathing with the swing phases.

Reps lack explosive power. Lifter is going through the motions without maximal effort per rep.

Bell does not reach approximately chest height at the top of the swing, indicating insufficient power.

Lifter uses arms or lower back to pull the bell forward instead of driving through the legs and hips.

At the deepest point of the backswing, arms have separated from the body and bell is not an extension of the arms.

Lifter bends forward without pushing hips back, missing the hip hinge that powers the swing.

Lifter hips-back while the bell is still out in front, creating a long lever arm that loads the lower back.

Lifter actively pulls the kettlebell down from the top instead of letting gravity do the work.

Lifter does not drive through to full hip extension and alignment at the peak of each swing.

Lifter shifts weight unevenly or lifts toes/heels during the swing.

The elbows bend during the deadlift, meaning the arms are pulling instead of acting as passive hooks. The work should come from the legs and hips, not the arms.

When reversing the get-up from standing, the wrong leg steps back into the lunge. The leg on the same side as the kettlebell should stay in front; the opposite leg goes back.

Keeping the fingers wrapped around the handles when racking two kettlebells. When the handles clang together, fingers get caught between them.

The backswing and drive lose the stiff hip-hinge pattern — the shins tip forward and the knees travel, turning the movement into a squat instead of a hinge.

The backswing and drive stay a stiff hip-hinge with no knee travel, instead of the shallow squat pattern StrongFirst technique calls for.

Starting the dead-start rep from the wrong place: yanking the kettlebell off the floor with the arm or the back, or building tension and pulling before the hips move.

The arm does not reach a straight-arm lockout, the legs re-dip instead of staying extended, or the kettlebell/body is not motionless before the descent begins.

Insufficient hip drive means there is no real ballistic float — the arm has to press/muscle the bell the rest of the way up from too low a point.

The arm pulls the bell up and it swings wide of the body instead of staying close and on the centerline, driven by the hips and legs.

The hand does not punch/spear through the handle early and at eye level, risking the bell banging the forearm.

The wrist/forearm rotates the bell on the way up or down (corkscrew) instead of a straight path, or the body rotates to compensate.

The kettlebell touches the chest or shoulder on descent, the drop is not one uninterrupted motion, or the lifter hinges before the bell has reached the backswing.

The non-working hand rests on the knee or thigh for support instead of the hip or waist.

The exhale is not a sharp, forced "tsss" through the teeth timed to the hip drive, or the inhale is not a sharp nasal breath on the backswing.
