- Wall balls are station 8 of 8, the last thing standing between you and the finish line.
- Every division throws 100 reps. Division changes the ball, never the rep count.
- In the singles divisions, target height is set by gender: 2.7 m for women, 3 m for men. Racing Pro raises the ball, not the target.
- Two things get you no-repped: a hip crease that does not drop clearly below the knee, and a ball that misses the target.
- The station is won earlier in the race. Arrive with legs, then break the reps on a plan you set before the gun.
What HYROX wall balls actually are
Wall balls are station 8 of 8 in a HYROX race, which runs as eight rounds, each a 1 km run followed by one functional workout station. One rep starts standing with the ball at your chest. You squat until the hip crease drops clearly below the top of the knee, drive up, and throw the ball so it strikes your assigned target overhead. You catch it, and you do it again, 100 times. Judges watch two things: depth and target contact.
The movement itself is unremarkable. Any gym does it. What makes this version brutal is where it sits: you reach the ball after 8 km of running and every other station in the race, with sandbag lunges, station 7, immediately before it. Your quads are already finished before the first rep. The full station-by-station guide maps the whole sequence: SkiErg, Sled Push, Sled Pull, Burpee Broad Jump, Rowing, Farmers Carry, Sandbag Lunges, Wall Balls.
The standards in one table
Four singles divisions race the station: Women, Women Pro, Men, and Men Pro. Ball weight changes across them, target height changes only with gender.
| Division | Ball weight | Target height |
|---|---|---|
| Women | 9 lb (4 kg) | 2.7 m |
| Women Pro | 13 lb (6 kg) | 2.7 m |
| Men | 13 lb (6 kg) | 3 m |
| Men Pro | 20 lb (9 kg) | 3 m |
The rep count is 100 for all four. Read the Pro rows again if you expected a higher target: PRO divisions use heavier loads than Open, and on this station that means a heavier ball thrown to exactly the same height as the Open division of the same gender. For the full per-division breakdown including doubles and relay, our wall ball weights and reps reference carries every load class in one place.
What the equipment is
The ball is a soft, oversized medicine ball with a matte, non-slip shell, supplied by the official equipment partner and identical at every venue. It is noticeably larger and softer than a basketball, and it is emphatically not a hard slam ball. That matters for training: a slam ball is a poor substitute because it is smaller, denser and punishes a sloppy catch in a way the real ball does not.
The target is a single flat strike plate or marked line mounted high on the rig, roughly a metre above where a standing athlete can reach. From the floor you are looking steeply upward at it, which is the part athletes underestimate when they train on a lower gym target.
The movement, rep by rep
Four positions, each with one cue worth more than a paragraph of theory.
The rack position
Ball under the chin, elbows tucked in and slightly forward, the ball resting on your chest rather than held out in front of you by your arms. The single biggest energy leak on this station is carrying the ball away from the body, because your shoulders end up doing an isometric hold for several minutes on top of every throw. If your elbows are flaring wide, you are already paying a tax you will feel at rep fifty.
The squat
Feet just outside shoulder width, toes turned slightly out, hip crease clearly below the top of the knee. Depth is the criterion the judge is watching, and it is the first thing fatigue steals. Nobody decides to squat higher. It happens quietly, a centimetre a rep, until a judge calls one back and you discover the last dozen were borderline too. Pick a depth that is obviously below the line rather than on it.
The drive and the throw
Treat the squat and the throw as one continuous action. Your hips and legs launch the ball, your arms only guide it. If your shoulders are doing the throwing, the set dies early and there is no recovering it mid-station. The ball should travel steeply upward toward the target, not forward. Athletes who throw forward end up chasing the catch a step out of position, which costs balance on the next squat.
The catch and the reset
Receive the ball high with soft elbows and let it ride down into the next squat. Catching low and re-lifting it to the rack is a hidden rep tax, a small extra pull repeated 100 times. Absorb the ball rather than blocking it, and let its own weight help drive you into the bottom position instead of fighting it there.
How judges score HYROX wall balls
Judging here is simple and unforgiving. A rep that does not reach depth does not count. A rep where the ball does not strike the target does not count. Either way you repeat it, which means a no-rep costs you the rep you just did and the one you now have to do again.
- Depth. The hip crease must drop clearly below the top of the knee. Borderline is judged as short.
- Target contact. The ball must visibly strike your target. Grazing the edge or hitting the rig beside it does not count.
- Your own target. Each athlete is assigned a lane and a target. Hitting a neighbour's is not your rep.
- The standing position. Each rep begins with hips and knees extended, ball at the chest. Rolling straight from a catch into a half squat without ever standing is not a completed rep.
One allowance surprises people: you can take your shoes off once you reach your assigned target, and plenty of racers do it for comfort on wrecked feet. The rulebook asks you to stow them under the rig, and it is the one stated exception to the closed-toe shoe rule. Take them with you when you leave, though. You cannot walk back into the wall ball area to collect them, so they travel with you to the Finisher Stage.
The heavy-ball myth and other bad numbers online
Two figures circulate widely and both are wrong.
The first is the ball weight ceiling. Search results and AI summaries routinely quote a top-end weight pulled from retail catalogues rather than the rulebook. Retailers sell wall balls heavier than any HYROX division throws, because gyms buy them for other purposes. The heaviest ball in competition is 20 lb (9 kg), thrown by Men Pro. Nothing above that appears on a race floor.
The second is the rep count. The old figure of 75 reps for women is dead and has been for seasons. It is 100 for every division in Season 9 (2026/27), men and women, Open and Pro. If a page tells you otherwise, it has not been updated. The wall ball weights reference lays out the current numbers division by division.
Rep-break strategy: how to split 100 reps
Decide your break scheme before the race, not at rep forty. At rep forty you are not making a decision, you are reacting to pain, and the plan you improvise there is always worse than the one you wrote down on fresh legs.
Three shapes cover almost everyone. Even blocks divide the total into equal chunks with identical rests, which is the easiest to hold and the easiest to count when your brain has stopped working properly. Descending blocks start large and shrink as you go, matching the reality that your capacity falls off through the set. Front-loading takes a big opening block and then grinds out small sets, which suits athletes with genuine engine and a short tolerance for standing around.
Whichever you pick, measure your breaks in breaths rather than seconds. Nobody counts seconds accurately at that point in a race, and a break defined as "a few seconds" reliably stretches into twenty. Three breaths is a break. Ten breaths is a rest, and it is where races quietly leak minutes.
The first block should feel too easy. If block one leaves you gasping, the scheme is already dead and you have another eighty-odd reps to discover it.
Rich Ryan, a three-time Elite 15 World Championship qualifier, walks through set sizing, breathing and shoulder management across the full station in this breakdown.
Breathing and the shoulder problem
Breathe at the top of the throw, not at the bottom of the squat. Trying to inhale while folded in half with a ball on your chest gives you half a breath, and you need the full one. Tie the exhale to the launch and the inhale to the moment the ball is airborne.
During a break, drop your arms and shake them out at your sides. Holding the ball or resting your hands on your knees keeps your shoulders loaded and your chest compressed, so the break gives back far less than it should. Arms down, chest open, count breaths, go again.
The station is won before you reach it
You arrive at wall balls having run 8 legs of 1000 m each and passed through ROXZONE, the central transition zone athletes run through between every run and station, after every one of them. Sandbag lunges come immediately before, which means the quads that have to produce 100 squats have just been emptied by station 7.
That sequencing makes the last run leg a lever rather than a formality. Running it hard to save fifteen seconds buys you a station you cannot execute, and the no-reps alone will cost more than the fifteen you saved. The same goes for sprinting the transition: the seconds are real but small, and arriving at the target with your heart rate pinned is the expensive way to start a set of 100 squats.
The athletes who finish this station well are almost never the ones who arrive at it fastest. They are the ones who arrived able to hold depth.
Training HYROX wall balls for race day
Three principles, and most athletes only follow the first.
Train the volume tired. You will never touch this ball with fresh legs in a race, so stop practising it that way. Put the reps after intervals, after a run, after lunges. A technique that holds up in a rested gym session tells you nothing about what happens at rep eighty with a heart rate near the ceiling.
Throw to your actual target height. Train to 2.7 m if you race women's divisions, 3 m if you race men's. A lower gym target trains a shorter throw, and the difference shows up as a string of missed targets in the second half of the race when your throw height starts to sag. If your gym target is lower, mark the correct height on the wall and use that.
Separate technique days from capacity days. Build the pattern fresh and at low volume, where you can hold perfect depth and a tight rack on every single rep. Then find out whether it survives somewhere else entirely, tired and at high volume. Try to do both at once and you get neither.
Not sure which ball your division throws? Check your load before you plan your sets.
Structured weeks that build this capacity sit in our HYROX training guide, and individual sessions you can drop in are in our HYROX workouts library.
Doubles and relay wall balls
HYROX runs as Singles, Doubles, Team Relay (4 athletes), and Adaptive. In doubles, only one partner works at a time, and you may swap as often as you like until the division rep count is complete. There is no prescribed split, so an even share and a lopsided one are equally legal.
Doubles use the Open loads: 9 lb (4 kg) for doubles women and 13 lb (6 kg) for mixed. The practical advice is to agree your swap trigger before the race, in reps rather than in feel. Feel is the first thing to go, and the partner under the ball is always the worst judge of how much is left. Our guide to racing HYROX doubles covers the wider work-split strategy.
Frequently asked questions
What is the rule for wall balls in HYROX?
Each rep starts standing with the ball at your chest. You squat until the hip crease drops clearly below the top of the knee, then drive up and throw the ball so it strikes your assigned target. Miss the depth or miss the target and the rep does not count, so you repeat it.
How many wall balls are in a HYROX race?
100 reps, and that figure is identical for every division. Open, Pro, men and women all throw the same count. What changes between divisions is the ball weight, and target height changes by gender. The older figure of 75 reps is out of date.
What weight are the wall balls in HYROX?
Women throw 9 lb (4 kg), Men throw 13 lb (6 kg), Women Pro throw 13 lb (6 kg) and Men Pro throw 20 lb (9 kg). Retailers sell heavier balls than any division actually uses, which is where most of the online confusion comes from.
How high is the HYROX wall ball target?
Target height tracks gender rather than division. Women and Women Pro throw to 2.7 m, men and Men Pro throw to 3 m. Pro Women throw to 2.7 m, the same target as Open Women.
Do Pro athletes throw to a higher target?
No. PRO divisions use heavier loads than Open, and on this station the heavier load is the only change. A Pro athlete throws a heavier ball to exactly the same height as the Open athlete of the same gender, which is why the Pro rows in the table above share their target with the Open rows.
How do you get 100 unbroken wall balls in HYROX?
Most racers should not try. Going unbroken is a narrow elite tactic, and for everyone else a planned break scheme finishes faster than a heroic set that collapses at rep sixty. Decide your blocks before the race, breathe at the top of each throw, and hold your breaks to a fixed number of breaths.
What are the most common HYROX wall ball mistakes?
Four repeat offenders: losing squat depth as fatigue builds, letting the ball drift away from the chest, throwing with the shoulders instead of the legs, and aiming at the wrong lane target. The first two cause most no-reps. The third is why so many sets die around rep thirty.
Can you take your shoes off for wall balls in HYROX?
Yes. Athletes are allowed to remove their shoes once they reach their assigned wall ball target, and plenty do it for comfort on tired feet. The rulebook asks you to stow them under the rig, and it is the one stated exception to the closed-toe shoe requirement. Budget the seconds it costs to get them off and back on, and remember they leave with you: you cannot re-enter the wall ball area once you are done.
Why are HYROX wall balls so hard?
Because of where they sit. This is station 8 of 8, reached after 8 km of running and every other station, with sandbag lunges immediately before. Your quads are gone before the first rep, so a movement that feels easy in a gym costs several times more here.
What ball does HYROX use for wall balls?
A soft, oversized medicine ball with a matte non-slip shell, supplied by the official equipment partner and the same at every venue. It is noticeably larger and softer than a basketball and is not a hard slam ball, which is why gym slam balls make poor training substitutes.
How do wall balls work in HYROX doubles?
Only one partner works at a time. You alternate as often as you like until the full division rep count is complete, so you can run even blocks or let the stronger partner take more. Doubles use Open loads: 9 lb (4 kg) for women and 13 lb (6 kg) for mixed.
Should I train wall balls fresh or tired?
Tired, mostly. In a race you never touch the ball with fresh legs, so build the capacity after running or intervals. Keep one separate fresh session for technique work, where you can hold perfect depth and a tight rack position without fatigue rewriting your mechanics.
