Most people who sign up for their first HYROX spend the whole training block worrying about the sled. It is heavy, it looks brutal, and it gets all the attention. Then race day comes. They survive the sled, grind through seven stations and eight kilometers of running, and find out the hard way that the thing that actually breaks them is the very last station. It is a rubber ball that weighs about as much as a couple bags of sugar.
HYROX wall balls are the eighth and final station: 100 reps of throwing a medicine ball up to a target, performed on legs that are already cooked from 8km of running and seven other stations. The ball is light, 6kg for Open men and 4kg for Open women, but the rep count and the fatigue make it the easiest place in the whole race to bleed time. Getting good at it is not about strength. It comes down to pacing, clean squat depth, and a plan you lock in before you pick up the ball.
That is the short version. If you want to walk off the floor with a time you are proud of, here is everything that matters about the station.
What a wall ball rep actually looks like
You hold the medicine ball at your chest. You squat down until your hips drop below the top of your knees. You drive up hard and throw the ball so it hits a target line on the wall above you. You catch it on the way down, ride straight into your next squat, and repeat. One hundred times.
It sounds simple, and on fresh legs it is. The catch is that you never do wall balls on fresh legs in a race.
HYROX wall ball standards: weight, reps, and target
The exact numbers depend on your division. Here is where they stand for the 2025/26 season:
- Men Open: 6kg ball, 100 reps, 10 foot (3.0m) target
- Women Open: 4kg ball, 75 reps, 9 foot (2.7m) target
- Men Pro: 9kg ball, 100 reps, 10 foot (3.0m) target
- Women Pro: 6kg ball, 100 reps, 9 foot (2.7m) target
One change worth knowing if you raced before: HYROX dropped Women Open from 100 reps to 75 for this season. Open women were spending so long at the final station compared to the men that it skewed finishing times, so the rep count came down to even things out.
On every rep, the center of the ball has to touch or cross the target line for it to count. Close does not count, and a judge can overrule the rep counter if you come up short.
Why the lightest station is the one that wrecks people
There are two reasons. The first is where it sits in the race. Wall balls are station 8. By the time you get there you have run 8km and already cleared the SkiErg, the sled push, the sled pull, burpee broad jumps, the row, the farmers carry, and the sandbag lunges. That last one matters. You walk into the wall ball station on legs that just finished a hundred plus meters of weighted lunges, and a wall ball is just a squat you have to do 100 times.
The second reason is measurable. A 2021 study by Brandt and colleagues recorded blood lactate peaking around 8.5 mmol/L at the wall ball station, the highest reading of any station in the race. Your legs are not tired in a vague way. They are flooded, and the ball does not care.
That combination is why I watch first-timers fall apart here more than anywhere else. They trained the movement fresh, never under fatigue, and the station feels like a completely different exercise on race day.
The no-rep trap
Nothing torches a wall ball time like no-reps. Every one costs you the energy you already spent plus the time to redo it, and in 2025 HYROX added time penalties of 15 or 30 seconds for things like coming up short on squat depth or missing the target.
The trap is a feedback loop. Your legs are gone, so you start cutting your squat shallow and rushing the throw just to get the set over with. Shallow squats and rushed throws are exactly what gets no-repped. Now you are doing extra reps, which fatigues you more, which causes more no-reps.
The fix sounds backwards: slow down before your legs force you to. A planned five second rest standing at the ball is almost always cheaper than a no-rep and the scramble that follows it.
How to pace 100 wall balls
Decide your breakdown before you touch the ball. Do not wing it and hope you can go unbroken, because almost nobody can at the end of a race. Pick a plan and commit to it.
Common breakdowns that hold up are 25-15-10-5, five sets of 20, or ten sets of ten with a few breaths between each. The exact split matters less than having one at all. The athletes who blow up are the ones who go to failure on the first set, stand there gassed, and then face 70 reps with no plan and no gas.
A few technique cues that save real time:
Drive the ball with your legs and hips. Your arms only guide it. If you try to muscle a 6kg ball up with your shoulders, you will gas out fast and your last 40 reps will fall apart. Catch the ball at chest height and let that catch flow you straight into the next squat instead of stopping and resetting every single rep. Stand about a foot back from the wall so the ball drops to you instead of rebounding into your face. Breathe in at the bottom of the squat and out as you throw.
How we train it at The Detour Gym
We coach a lot of first-time HYROX athletes, and wall balls are the station we drill the most. The reason is simple. Anybody can throw a ball at a wall when they are fresh. The skill is throwing it clean when your heart rate is pinned and your quads are shaking, so that is exactly how we program it, layered into conditioning so your legs are already tired by the time the ball comes out.
We are an Official HYROX Training Club, so the standards we hold you to are the real ones. If you want the full picture of how the race is built and how long it takes to get ready, I wrote a separate guide on how long it takes to train for your first HYROX. You can also see how the whole HYROX program fits together on our site.
FAQ
How many wall balls are in HYROX? One hundred in every division except Women Open, which dropped to 75 reps for the 2025/26 season. Men Open, Men Pro, and Women Pro all do 100.
How heavy is a HYROX wall ball? Men Open use a 6kg ball, Women Open use 4kg, Men Pro use 9kg, and Women Pro use 6kg. The men throw to a 10 foot target and the women throw to 9 feet.
Why are HYROX wall balls so hard? They are the final station, done after 8km of running and seven other stations, including weighted lunges right before. Your legs are already maxed out, and a wall ball is a squat. Blood lactate runs higher here than at any other station in the race.
How do you avoid no-reps on wall balls? Squat until your hips drop below your knees on every rep, and make sure the ball clearly hits the target line. The most common cause of no-reps is rushing with tired legs, so plan short breaks and keep your depth honest even when you are smoked.
