HYROX Wall Balls: Weights, Rules, Technique & Tips

Wall balls are the eighth and final workout station in HYROX. After completing 8km of running and seven other workout stations, every athlete must finish with 100 wall ball repetitions (if you’re new to the overall race format, our complete beginner’s guide to HYROX explains all eight runs and workout stations).

It is a brutal way to end the race. Your legs, shoulders and breathing are already under pressure, while every repetition must still meet the required squat depth and target standard. This guide covers the HYROX wall ball weights, target heights, rules, technique, pacing and training strategies.

HYROX Wall Ball Requirements (reps, weights, and target height)

HYROX Wall Ball Rules and Movement Standards

You must begin the station standing tall with your hips and knees fully extended, holding the wall ball in both hands. You cannot pick the ball up from the floor and immediately throw it at the target.

Each valid wall ball repetition must follow this sequence:

• Complete a full squat with your hips descending lower than your knees
• Drive upwards and throw the ball using both hands
• Make contact with the correct target and strike zone
• Catch the ball and begin your next repetition, or allow it to land before resetting

If you allow the ball to hit the floor, you must stand tall with your hips and knees extended before beginning the next squat. You cannot catch the ball after it bounces and continue directly into another repetition.

Wall Ball No-Reps and Penalties

There are no formal warnings for an invalid wall ball. A repetition either meets the required standard or is recorded as a no-rep.

HYROX events may use digital screens to display your repetition count and identify movement or target faults. However, the screen is only a visual aid. The physical target and judge’s decision remain the official standard.

A squat-depth box may be introduced at the judge’s discretion if they need help assessing your squat depth. You cannot request a box, and you cannot use it for sitting or resting.

You may remove your shoes when you arrive at the wall-ball station, but they must be placed underneath the rig and taken with you when you finish.

Using powdered chalk at the wall-ball station results in a two-minute penalty. Leaving the station without completing 100 valid repetitions can result in disqualification for an incomplete station.

Below is a HYROX video covering the wall ball standards…

What Wall Balls Are Used in HYROX?

HYROX uses official competition wall balls made by Centr, its official equipment provider. The competition balls are available in the required 4kg, 6kg and 9kg weights and have a grippy, double-stitched outer shell designed to maintain their shape.

You do not need the official ball for your training, but you should use the correct race weight and, where possible, a ball with a similar size and feel. This will help you practise your catching position, throwing accuracy and rhythm before race day.

HYROX Wall Balls Technique

Efficient wall-ball technique helps you meet the movement standard while reducing unnecessary fatigue in your shoulders and legs. Your exact stance and distance from the target will depend on your height, mobility and throwing style, so test different positions during training.

Starting Position

Stand approximately one arm’s length from the wall-ball rig. Use a stable stance, with your feet around shoulder-width apart and your toes turned slightly out if required.

Hold the ball close to your chest rather than away from your body. This reduces the strain on your shoulders and helps you maintain a neutral spine.

The Squat and Throw

Begin each repetition by sitting into a full squat, ensuring your hips descend lower than your knees.

Drive upwards using your legs and hips before guiding the ball towards the target with your arms. Avoid relying mainly on your shoulders. Some athletes find that allowing their heels to rise slightly at the top of the movement provides additional power, although this will depend on your height and technique.

Your hands only need to guide the ball high enough to strike the correct target. Throwing it significantly higher wastes energy and makes the next catch less predictable.

Catching the Ball

Keep the ball close to your body as you catch it. Begin moving downwards into your next squat as you receive the ball, rather than catching it with straight legs and then starting the squat.

This creates a smoother rhythm and reduces the amount of time spent holding the ball. Try to keep each repetition consistent, with the ball following the same path towards the target and back into your hands.

Breathing During Wall Balls

Develop a repeatable breathing pattern during training. One approach is to breathe in as you descend into the squat and breathe out as you drive upwards and release the ball.

Avoid holding your breath for multiple repetitions. Controlled breathing becomes particularly important during HYROX because you reach the wall balls after 8km of running and seven other workout stations.

How to Train for HYROX Wall Balls

Your wall-ball training should develop efficient technique, strength, muscular endurance and the ability to maintain the movement standard when fatigued.

Practise at Your Race Weight and Height

Most of your wall-ball training should use the weight prescribed for your HYROX division. You should also measure the target height rather than assuming that your gym’s target matches the official 2.7m or 3m standard.

Use these sessions to develop a repeatable throwing path, comfortable catching position and consistent squat depth.

Build Your Wall-Ball Volume Gradually

Increase your volume gradually rather than attempting 100 fatigued repetitions in every session. Smaller sets allow you to practise good technique without every workout becoming a race simulation.

One example session is:

• Complete 10 wall balls at the start of every minute

• Continue for 10 minutes

• Use your HYROX race weight

• Focus on consistent technique and breathing

This provides 100 repetitions while giving you some recovery within each minute. Adjust the number of repetitions if your technique begins to deteriorate.

Develop Supporting Strength

Wall balls use your quads, glutes, core, shoulders and triceps. Squats, front squats, thrusters and overhead pressing can therefore support your wall-ball performance.

These exercises should complement your wall-ball practice rather than replace it. You still need to train the timing, accuracy and rhythm of the complete movement.

Include Compromised Wall Balls

Wall balls feel very different after running and completing other workout stations. Include compromised HYROX training so you can practise maintaining your squat depth, accuracy and breathing while fatigued.

You could begin with three or four rounds of running followed by 20 to 25 wall balls. As your race approaches, include occasional sessions where you complete all 100 repetitions after a demanding running or HYROX workout.

Practise Your Race-Day Rep Strategy

You should know approximately how you intend to divide the 100 repetitions before race day. Test different set sizes during training and record how much rest you need between them.

Your best strategy is the one that allows you to complete all 100 valid repetitions quickly without reaching failure early and needing a long recovery.

HYROX Wall Ball Pacing and Race-Day Tips

Empty the Tank

The wall balls are an important station where there is a large variability in the times that athletes complete it in.  But, unlike with other stations where that applies, you can push yourself to your absolute limit to get them done because it’s the end of the race.  This is where leaving something in the tank goes out the window – by the time you reach the wall balls your tank will likely be almost empty, and you should use the wall balls to fully empty it!

How to Break Up 100 Wall Balls

If you cannot complete 100 wall balls unbroken, you need a plan for dividing the repetitions. Avoid reaching complete failure during your opening set if it means you then need a long rest before continuing.

That said, I have found that doing too few repetitions in the first set can make the whole station feel like more of a mental battle. I prefer to complete a good portion of the repetitions while keeping approximately five to ten reps in reserve.

Elite HYROX athlete Cole Learn discussed this when he joined me on the Rox Lyfe podcast:

“I know for myself, if I set the ball down, I’m toast. As soon as I set it down, that’s when all the fatigue comes in. You think you’re going to feel better going into that next set, but you feel a hundred times worse.”

As your race approaches, test different strategies during training. One option is to complete sets of 16, 15, 14, 13, 12, 11, 10 and 9 repetitions, which adds up to exactly 100.

It is impossible to know precisely how you will feel after the first seven stations, but having a flexible plan is better than making the decision while exhausted.

Mindset

There is a big mindset element that is involved in completion of the wall balls.  Your body and mind are already very fatigued by the time you get here, and you must try to stay focused through the duration of the 100 reps.

It is an area that many athletes – including Elli Stenfors – have spoken about on the Rox Lyfe podcast – believing that the wall ball station is a far more mental challenge than a physical one.  Elli has gone unbroken many times in HYROX at the wall balls.  She said she tricks her mind and tells herself to just do one more rep: “Basically you want to get rid of them as fast as possible… so I tell myself one more rep, and then I can break if I need to. And then suddenly you are at ninety and you’re like, okay, I don’t need to break anymore. I can go unbroken now.”  That approach may be easier said than done(!), but having a mental strategy that can work for you is worth thinking about in advance.

You also don’t want to let any no reps affect your mental state.  If a judge gives you a no-rep, focus on understanding and correcting the problem immediately rather than arguing and losing more time.

Gloves

Gloves are permitted during HYROX, but gymnastics grips are not. If you choose to use gloves, they must be worn or carried from the start of the race to the finish. You cannot collect them shortly before the wall-ball station.

Some athletes find that gloves provide a more secure catch when the wall ball becomes slippery. I personally like the gloves from The Rox Guyz.  If you want to try them use that link to get a 15% discount applied at checkout.

Powdered chalk is not permitted at the wall-ball station. HYROX only allows event-provided chalk at the sled pull and farmers carry. Using chalk during the wall balls results in a two-minute penalty.

Final Thoughts

Respect the placement of wall balls in the race. They are not just another station. They are the final test of pacing, posture, and composure.

Train them under fatigue. Practice your break strategy. Build aerobic capacity so your breathing stays controlled. Improve mobility so technique does not collapse.

If you arrive at the final station calm and confident, you will pass athletes who relied only on grit.

Wall balls do not reward chaos. They reward preparation.
