HYROX Wall Ball: Perfect Technique for 100 Reps (No-Rep Free)
Station 8 — the last one. You arrive with 8 km of running and 7 stations in your legs. Ahead of you: 100 wall balls (men) or 75 wall balls (women). This is the station that makes people cry in the HYROX community, and where most time is lost due to no-reps. Here’s the technique to string them together cleanly.
The precise format
| Category | Ball weight | Target (height) | Reps |
|---|---|---|---|
| Open men | 9 kg | 3.05 m | 100 |
| Open women | 6 kg | 2.75 m | 75 |
| Pro men | 14 kg | 3.05 m | 100 |
| Pro women | 9 kg | 2.75 m | 75 |
The ball must touch the target (the line or official marker) with each rep. And you must catch the ball without it touching the ground — otherwise it's a "no rep".
The perfect technique (5 phases)
Phase 1 — Starting position
Feet shoulder-width apart, ball held at chest height, elbows tucked close to the body. You look at the target, not the ball. Not the ground. The target.
Phase 2 — The squat
Controlled descent until the hip crease passes below the line of the knee. This is the HYROX judging criterion — if you don't go low enough, it's a no-rep.
Common errors:
- Knees caving inwards (valgus)
- Heels lifting
- Rounded back at the bottom of the squat
Good cue: your elbows touch the inside of your knees at the bottom.
Phase 3 — The explosive drive up
You explode from the hips to throw the ball. The throwing force comes from your legs and hips, not your arms. Your arms are just for guiding. If you throw with your arms, you'll burn out in 30 reps.
Phase 4 — The throw
The ball leaves your hands just as you complete your hip extension. Trajectory: directly towards the target, not in too curved an arc. The ball must hit the target with some momentum — not weakly.
Phase 5 — The catch and transition
You follow the ball with your eyes. Arms extended, ready to catch it. You absorb the rebound by immediately beginning the next squat flexion. The rhythm is built on the controlled rebound, not on pausing.
Breathing rhythm
This is what separates athletes who do 100 wall balls non-stop from the others:
- Inhale during the squat descent
- Explosive exhale during the throw
- 1 breathing cycle = 1 rep
If you hold your breath for several reps, you'll hyperventilate in 20 reps. If you breathe "out of sync" with the rhythm, you'll be off-tempo. Practice coupling rhythm and breathing in training.
The 5 mistakes that waste your time
1. Not squatting low enough → no-rep
Number one. When fatigued, you'll tend to shorten the descent. If the judge gives you a no-rep, you have to do it again. It's better to go 5 cm too low than 1 cm not low enough.
2. Ball not hitting the target → no-rep
Often due to leg fatigue: you can no longer throw the ball high enough. Avoid this by managing your effort for the first 70 reps.
3. Throwing with your arms
You'll blow out your triceps and deltoids in 30 reps. The throw = legs + hips.
4. Too long a pause between reps
Every pause costs time. Aim for a steady rhythm. If you need to pause, do it in sets of 10, not randomly.
5. Poor catch
If you don't follow the ball, you'll hit yourself in the head (yes, it's happened) or drop it. Keep your eyes on the ball as soon as you start to rise.
Strategy for managing 100 reps
Three approaches, to choose according to your level:
Strategy 1 — Non-stop (experienced athletes)
You do all 100 without stopping. Possible if you've practiced simulation. Aim for a pace of 20 reps/min (~5 min total).
Strategy 2 — 4 sets of 25 (intermediates)
You do 25-25-25-25 with 10 sec rest between. More mental, more secure. Target total: 6-7 min.
Strategy 3 — 10 sets of 10 (beginners)
You break it down into 10s with mini-pauses. Long but zero risk of cascading no-reps. Total: 8-10 min.
For your first HYROX, strategy 2 is the sweet spot. Strategy 3 if you don't feel confident with the technique.
Programming wall balls in your prep
3 typical sessions to integrate into your 8-12 weeks of prep:
Technique session (week 1-2)
- 5 × 20 reps with 60 sec recovery
- Exclusive focus on perfect technique
- Light ball (5-6 kg) if you're a beginner
Volume session (week 3-5)
- 4 × 30 reps with 45 sec recovery
- Race weight ball (9 kg / 6 kg)
- You can break it down into 15-15 if needed
Simulation session (week 6-7)
- 100 reps in race mode (20-25 reps/min)
- Preceded by 1 km of running to replicate cumulative fatigue
- Once a week is enough — it's intense
Equipment for home training
- Weighted medicine ball 6 kg (women) or 9 kg (men) — €35-60
- Outdoor wall or adhesive target at 3.05 m / 2.75 m
- If no wall: pseudo wall ball on the ground (ball in front of you, throw in the air, catch) — less ideal but useful

In summary
- Deep squat, hip crease below knee = absolute criterion
- Force from the legs, never from the arms
- Coupled breathing rhythm: 1 cycle = 1 rep
- Set strategy according to your level (non-stop / 4×25 / 10×10)
- Programming in prep: technique → volume → simulation
