Why the warm-up matters so much in Hyrox
The Hyrox format loads the whole body from the first kilometre: running, then SkiErg, sled, rowing, lunges, wall balls. Starting that kind of effort cold raises the risk of discomfort or injury and wastes your best minutes. A well-built warm-up prepares your cardiovascular system, joints and nervous system without tiring you.
A simple rule: the warm-up should make you sweat lightly and leave you energised, not exhausted. If you are already tired at the end, it was too intense or too long.
The routine in 4 phases (15 minutes)
Phase 1 — Raise your temperature (5 minutes)
Rowing, cycling or easy running at progressive intensity. Start at a level where you can talk easily and finish at a firm but comfortable pace. Before a running session, you can do this part as a light jog.
Phase 2 — Mobility (4 minutes)
- Hips: low lunges with rotation, 5 per side.
- Ankles: knee-to-wall or step drives, 10 per side.
- Shoulders and upper back: arm circles then torso rotations, 10 each.
- Spine: cat-cow on the floor, 8 slow reps.
Phase 3 — Activation (3 minutes)
- Glutes: glute bridges or banded lateral walks, 2 sets of 12.
- Core: plank 2 × 20 seconds or side plank 2 × 15 seconds per side.
- Shoulder blades: band pull-aparts or light face pulls, 12 reps.
Phase 4 — Specific movements (3 minutes)
Rehearse the movements of the session or race at light intensity: 2 minutes of technical SkiErg or rowing, a few wall balls or squats with very light weight, then 2 accelerations of 20 to 30 seconds running, with full recovery in between. These accelerations wake up the nervous system without tiring you.
Adapting the warm-up to the session
- Heavy session (sled, squat, deadlift): add 2 to 3 build-up sets (50%, 70%, 85% of your working weight) before the first working set.
- Running session: replace phase 1 with 8 to 10 minutes of easy jogging and add 4 progressive strides.
- Race day: keep the same routine, validate it in training beforehand, and test nothing new. See also our race day guide.
Common mistakes
- Warming up for too long: beyond 20 minutes you burn useful energy.
- Long static stretching before effort: it is more useful after the session. Before, prefer dynamic movements.
- Skipping ankle and hip mobility: they limit the quality of lunges, squats and running.
- Jumping straight to heavy loads: progressive loading is the most protective part.
The short version: 8 minutes when time is tight
Some days you do not have 15 minutes. Here is a short version that keeps the essentials:
- 3 minutes of rowing or cycling, progressive;
- 2 minutes of mobility: low lunges with rotation and shoulder circles;
- 1 minute of activation: glute bridges and plank;
- 2 minutes of specific movements: a few light reps of the session's main movement.
This version remains useful for a short session or a workout away from the gym, but it does not replace the full routine before a heavy session or a race.
Warming up for each station
Each station loads different areas. A few specific repetitions at very light intensity are enough to prepare the movement:
| Station | Areas to prepare | Specific warm-up |
|---|---|---|
| SkiErg | Shoulders, lats, core | 2 minutes at low resistance, then 3 firmer 10-second pulls. |
| Sled push | Quads, glutes, ankles | 2 passes empty or with a light load, trunk braced. |
| Sled pull | Back, biceps, forearms | Band pulls, then 2 light passes. |
| Burpee broad jumps | Shoulders, hips, wrists | 5 slow burpees, then 3 moderate broad jumps. |
| Rowing | Legs, back, hamstrings | 2 minutes of pure technique, then 3 strokes at 80% of target intensity. |
| Farmers carry | Forearms, traps, core | Walk with a light load over 20 metres, shoulders down. |
| Sandbag lunges | Hips, knees, glutes | 10 bodyweight lunges, then 5 with an empty or light bag. |
| Wall balls | Quads, shoulders, ankle mobility | 10 mobility squats, then 8 to 10 throws with a light ball. |
A sample build-up
Before a heavy squat or sled set, avoid jumping straight to working weight. Here is a typical progression for a working weight of 100 kg:
- Empty bar or 30 kg: 10 reps;
- 50 kg: 6 reps;
- 70 kg: 4 reps;
- 85 kg: 2 reps;
- Working weight: first useful set.
Rest between these warm-up sets stays very short (30 to 60 seconds): their purpose is to prepare, not to tire.
When you feel stiff or sore
Hard mornings exist. If your hips or shoulders are stiff, extend phase 2 by 2 to 3 minutes and choose slow, wide movements. If sharp pain appears or persists during the warm-up, do not mask it: adapt the session, reduce the load or postpone it. Persistent discomfort deserves the advice of a healthcare professional. Our article on injury prevention details the areas to watch.
The cooldown: the other half of the routine
After the session, spend 5 minutes coming down gently: 2 to 3 minutes of very easy walking or cycling, then a few stretches held for 20 to 30 seconds on quads, calves, glutes and shoulders. It is also a good moment to drink and note how you feel. This simple ritual helps you link the week's sessions with more freshness.
Race day: adjusting the timing
On race day, finish your warm-up 10 to 15 minutes before your wave to stay fresh and avoid cooling down. If your start is delayed, keep moving with a few minutes of active walking and light mobilisations. The race-day warm-up should contain nothing new: use the one you validated during previous weeks.
Building the habit
A warm-up only works if you do it consistently. Rather than searching for the perfect routine, choose a version you can repeat every session without thinking. Keep the same movements for 3 to 4 weeks, then vary them slightly according to your needs. Also note how you feel at the end of the warm-up: if you are slower or stiffer than at the start, it is a sign of fatigue to take into account. Many athletes find that after a few weeks of regular routine, their first sets are cleaner and they feel less joint discomfort the next day.
Finally, protect this time in your schedule. Fifteen minutes of warm-up are more profitable than fifteen extra minutes of poorly prepared training: they improve the quality of what follows and reduce the risk of having to stop because of avoidable discomfort.
Common warm-up mistakes
- Going too fast too soon: the first minutes should feel almost too easy. Intensity rises progressively.
- Only stretching: holding long static stretches on cold muscles does not prepare you for effort.
- Copying someone else's routine: a routine suited to a 90 kg athlete may not suit you. Adapt it to your stiff areas.
- Skipping the specific part: general cardio is not enough; the movement you are about to do must be rehearsed lightly.
- Making it too long: beyond 20 minutes, you start to spend energy you will need for the session.
Check your routine against this list once a month. A small adjustment is often enough to feel better from the first set.

Start FreeFrequently asked questions
How long should a Hyrox warm-up last?
Between 10 and 20 minutes. The 15-minute routine here suits most sessions and race day.
Should I stretch before training?
Prefer dynamic mobility before effort. Long static stretching is more useful at the end of a session.
Can I use the same warm-up for every session?
The base stays the same, but add a build-up before a heavy session and more easy running before a running session.
Should I warm up differently in cold weather?
Yes. Extend the first phase by 3 to 5 minutes and keep a warm top on until the session starts. The body needs more time to warm up.
Can I warm up with just the empty bar?
For a very simple exercise, yes, but prefer a progressive build-up before a heavy set. It prepares muscles and joints better.
Is static stretching useless?
It is not useless, but better suited to the end of a session. Before effort, dynamic movements prepare the body better.
