HYROX Warm-Up Guide: A Practical 20-Minute Routine Before the Start

1. Why HYROX needs a warm-up

HYROX starts with a 1 km run and then moves directly into SkiErg. If your body is still cold and your breathing is not settled, your heart rate spikes immediately and you reach Station 1 without any control over your effort. This kind of rough start often affects performance all the way through the second half.

At the same time, a warm-up that is too intense wastes glycogen and pre-loads fatigue into your legs before the race even begins. HYROX is a 60- to 100-minute race, so burning out your legs at the start line is counterproductive.

Four purposes of a HYROX warm-up

A useful HYROX warm-up targets exactly four things.

1. Raise body temperature: When muscle temperature increases, contraction speed and range of motion both improve. Light jogging or brisk walking until you feel a faint sweat is a good benchmark.
2. Open range of motion: Ankles, hips, thoracic spine, and shoulder blades all need to move freely. HYROX includes squat-pattern movements (Sled Push, Lunges, Wall Balls) and pulling movements (Sled Pull, Rowing), so both lower and upper body must be prepared.
3. Activate the nervous system: Light jumps and short accelerations switch on the neuromuscular connection. This prevents your legs from feeling heavy in the first few hundred meters of Run 1.
4. Set your breathing rhythm: By moving through a slightly elevated breathing state during the warm-up, you reduce the shock of the breathing spike that comes after the start.

Meeting all four of these targets takes 15 to 20 minutes. There is no need to spend more than 30 minutes.

Timing: when to start

HYROX uses a wave-start format, so you know your exact start time. Work backwards from that time with the following schedule.

• 40 to 35 minutes before your wave: Move to the warm-up area. Confirm when to drop your bag.
• 30 to 25 minutes before your wave: Start the warm-up. Begin with a light jog.
• 10 to 5 minutes before your wave: Finish the warm-up and move to the start corral.

One important note: if more than 10 minutes pass between finishing your warm-up and the start, your body will cool down. While waiting in the start corral, keep moving with marching in place, light calf raises, and gentle knee bends. Space in the corral is often limited, so stick to standing movements.

2. A practical 20-minute routine

This routine is designed to be reproducible at an actual HYROX venue. You do not need a large space; a straight line of 5 to 10 meters is enough.

Phase 1 (0-5 min): Raise body temperature

The goal is to gradually increase muscle temperature and heart rate. There is no need to run hard.

• Light jog or brisk walk for 3 to 5 minutes. Loop the warm-up area or jog in place if space is limited.
• Pace guide: conversational pace, roughly 110 to 120 bpm heart rate.
• Stop when you feel a gentle warmth across the body. A faint sweat is enough.

Phase 2 (5-12 min): Dynamic mobility drills

Use dynamic stretches (moving through range of motion) rather than static holds. Perform each of the following movements 5 to 8 reps, targeting the movement patterns used in HYROX.

Lower body (Run / Sled / Lunges / Wall Balls):

• Leg swings (front-to-back): Place one hand on a wall or post and swing one leg forward and back. Prepares the hip joint and hamstrings. 8 reps per leg.
• Leg swings (side-to-side): Same setup, swing the leg left and right. Prepares the adductors. 8 reps per leg.
• Walking lunge with torso twist: Step forward into a lunge, then rotate your upper body toward the front knee. Simultaneous preparation for hips, thoracic spine, and core. 5 steps per leg.
• Ankle circles: Place the ball of your foot on the ground and circle the ankle inward and outward. 10 circles per foot. Prepares for the landing impact of running.

Upper body (SkiErg / Sled Pull / Rowing / Wall Balls):

• Arm circles: Swing both arms in large circles. 10 forward, 10 backward. Opens the shoulder joints.
• Thoracic rotation: Stand with feet shoulder-width apart, clasp hands in front of your chest, and twist left and right. 8 reps per side. Prepares thoracic rotation for Rowing.
• Inchworms: From standing, place your hands on the floor, walk them out to a plank position, then walk your feet back to your hands and stand up. 3 to 5 reps. A full-body preparation for hamstrings, shoulders, and core.

Phase 3 (12-17 min): Muscle activation

Once range of motion is established, send a wake-up signal to your muscles. Keep the load light and focus on speed of movement.

• Air squats x 10: Bodyweight only. Drop deep and stand up quickly. Prepares for Wall Balls, Lunges, and Sled work.
• Reverse lunges x 5 per leg: Step backward into a lunge. Close to the movement pattern at the Lunges station.
• Light jumps x 5: Small vertical jumps with a controlled landing. Increases leg reactivity.
• Plank hold x 20-30 seconds: Switches on the core. Relevant for Sled Push and Farmers Carry.
• Band pull-aparts x 10 (if you have a resistance band): Activates the muscles around the shoulder blades. Useful for SkiErg, Rowing, and Sled Pull. Skip if you do not have a band.

Phase 4 (17-20 min): Race-pace rehearsal

Finish with a small dose of race-intensity movement. It is critical not to tire yourself out here.

• Short strides x 2-3 (30-50 m each): Run at roughly the pace you plan for Run 1. Not all-out; aim for 80-90% of your target run pace.
• Burpees x 3-5: Light and easy, just to confirm full-body coordination.
• Air squats x 5 (faster tempo): Remind your body of the Wall Balls rhythm.

After Phase 4, take 3 to 4 deep breaths to let your heart rate settle slightly before moving to the start corral.

Mental preparation: the last 2-3 minutes

While waiting in the start corral, run through your race plan once in your head. "Run 1 at X pace per kilometer." "Sled Push in Y sets." "Hold the pace in the second half." You do not need fine detail; just confirm the broad plan.

If nerves appear, remind yourself: "The warm-up is done. I have done what I can." Being nervous before a first race is completely normal, and a moderate level of nervousness actually improves performance. The real problem is not nerves; it is letting nerves push you into an unsustainable pace from the start.

3. Common mistakes

Here are the most frequent warm-up mistakes, explained in enough detail to recognize and avoid them.

Mistake 1: Pushing heart rate too high

Some athletes think they need to "really get the blood moving" and push their heart rate above 160 bpm before the race. This is not a warm-up; it is a training session. A warm-up heart rate of 130 to 140 bpm at peak is plenty. A brief spike during strides is fine, but if you are breathing hard during the jog phase, you have gone too far.

Mistake 2: Only doing static stretching

Sitting down for a straddle stretch, forward fold, or static shoulder hold and calling it a warm-up is a common pattern. Static stretching is useful for maintaining flexibility, but it does not raise muscle temperature or activate the nervous system. Before a HYROX start, prioritize dynamic stretching. If you want to include static stretching, limit it to 30 seconds or less and do it before Phase 2.

Mistake 3: Skipping the warm-up because the venue is crowded

Warm-up space varies dramatically between HYROX venues. Large international events often have generous areas, while some venues offer very limited room. However, jogging in place, lunges, squats, and ankle circles can be done in a space the size of a yoga mat. "There is no room so I will skip it entirely" is the worst choice available.

Mistake 4: Trying a brand-new routine on race day

Copying a routine from a YouTube video and trying it for the first time on race morning is risky. Test your warm-up routine at least two or three times during training. Check whether it fits within 20 minutes, how your body responds to each phase, and how you feel at the end. The ideal state on race day is simply reproducing what you have already practiced.

Mistake 5: Finishing the warm-up too early

If 15 to 20 minutes pass between the end of your warm-up and the start, your body temperature drops and much of the benefit is lost. Time your routine by working backwards from your wave start so that the 20-minute warm-up ends 5 to 10 minutes before the gun. If you arrive early and have time to spare, delay the easy jog in Phase 1 rather than starting the whole routine too soon.

4. How to adjust for venue conditions

Cold venue (winter / air-conditioned indoor)

When the temperature is below 15 C (59 F), it takes longer for body temperature to rise and muscles and joints tend to stay stiff. Make the following adjustments.

• Extend Phase 1 jogging from 5 minutes to 7-8 minutes.
• Keep a light layer (thin windbreaker) on during the warm-up and remove it just before Phase 4.
• While waiting in the start corral, continue marching in place, calf raises, and arm swings to maintain body temperature.
• Slightly increase the reps for jumps and lunges in Phase 3 to make sure muscle temperature is up.

Hot venue (summer / humid indoor)

When the temperature is above 28 C (82 F), reduce the overall volume. Your body temperature is already elevated, so excessive sweating increases dehydration risk.

• Shorten Phase 1 jogging to 3 minutes (brisk walking is also fine).
• Focus on Phase 2 mobility drills and keep additional temperature-raising work modest.
• Take small sips of water throughout. Aim for roughly 200-300 ml of fluid during the warm-up.
• Reduce Phase 4 strides to 1 rep, or skip them entirely.

Very limited space

Even if you only have the space of a yoga mat, the following minimal routine can be completed in 10 to 12 minutes.

1. Jogging in place: 3-4 minutes. Focus on arm swing to raise heart rate.
2. Stationary lunges: 5 per leg. Opens the hip joints.
3. Ankle circles: 10 per foot.
4. Air squats: 10 reps.
5. Arm circles: 10 forward, 10 backward.
6. Light jumps: 5 reps.
7. Deep breaths: 3-4 breaths.

This takes roughly 10 to 12 minutes total. The difference between doing this and doing nothing is significant; your legs will feel noticeably different at the start of Run 1.

Doubles / Relay

In Doubles, warming up together with your partner doubles as pre-race communication. Counting lunges for each other or matching light jog pace helps build a shared sense of pacing that carries into the race. That said, the warm-up content itself can be the same as for singles. If there is a fitness gap between partners, each person should warm up at their own pace.
