Rowing vs SkiErg in Hyrox

Two Concept2 Machines, Two Completely Different Problems

Every HYROX^® race contains two Concept2 machines. Station 1 is the SkiErg: 1,000 metres, standing, upper-body dominant, with fresh legs and a climbing heart rate after the opening run. Station 5 is the Rower: 1,000 metres, seated, full-body, arriving after the sled push, sled pull, and burpee broad jumps have systematically loaded every major muscle group you own.

Both are 1,000 metres. Both are ergometers. Both appear on the same Concept2 website. That is where the similarity ends.

The athletes who understand what separates these two machines — mechanically, physiologically, and tactically — train each one correctly. Those who treat them as interchangeable aerobic tools consistently underperform at one or both stations. The gap at each machine is not a fitness problem. It is a specificity problem.

This article breaks down exactly what makes rowing and SkiErg training distinct, why neglecting either one costs you race time, and how to structure both into a single programme that produces results at stations 1 and 5.

For a full breakdown of the SkiErg station within the race, see the HYROX^® SkiErg guide. For the rower, the HYROX^® rowing guide covers pacing targets and race-specific strategy in detail.

The Mechanical Difference: Standing Pull vs. Seated Drive

The most fundamental difference between the SkiErg and the rower is not aerobic demand — it is movement pattern. These machines recruit different primary movers, in different positions, through different ranges of motion. Training one does not prepare you for the other in the way that, for example, training running transfers to cycling.

SkiErg: The Standing Double-Pole

The SkiErg replicates the cross-country skiing double-pole stroke. You stand with both handles overhead at full arm extension. The movement initiates with a hip hinge — the torso drives forward and downward as the core braces — and the lats, triceps, and shoulders execute a long downward pull, finishing with the hands past the hips.

The primary movers are the latissimus dorsi, triceps brachii, anterior deltoid, and core. The legs provide a stable platform — some athletes incorporate a shallow knee bend at the top of the stroke — but they are not the engine. Rough power distribution on a correct SkiErg stroke: approximately 70–75% upper body and core, 25–30% partial leg contribution through the hip hinge.^[1]

This is unusual in HYROX^®, where most stations are leg-dominant or full-body. The SkiErg specifically taxes pulling musculature — the same muscles that are undertrained in most runners and gym athletes who have spent years developing their quads, hamstrings, and aerobic base through lower-body-dominant activities.

Rower: The Seated Chain Drive

The Concept2 RowErg is a full-body exercise with a completely different power hierarchy. The stroke begins at the catch — shins vertical, back straight, arms extended — and drives through a strict sequence: legs, then back, then arms. The legs initiate the drive by pushing against the footplate, the torso levers back from approximately 1 o'clock to 11 o'clock, and the arms draw the handle to the lower ribs to complete the stroke.

Power distribution on a correctly executed rowing stroke: approximately 60% legs, 20% back, 20% arms.^[2] The primary movers are the quadriceps, hamstrings, glutes, spinal erectors, lats, and biceps — a significantly larger combined muscle mass than the SkiErg engages. This is why most athletes are faster on the rower: more active muscle mass generates more total watts.

The seated position also changes the nature of fatigue. Unlike the SkiErg, where upper-body endurance is the bottleneck, the rower's limiting factor at station 5 is almost always leg drive quality under accumulated fatigue — quads and hamstrings that have already absorbed the sled push and sled pull before you sit down.

Head-to-Head: Rowing vs. SkiErg at a Glance

Factor	SkiErg (Station 1)	Rower (Station 5)
Distance	1,000m	1,000m
Position	Standing	Seated
Primary muscles	Lats, triceps, shoulders, core	Quads, hamstrings, glutes, spinal erectors, lats, biceps
Muscle mass recruited	Moderate — upper body + core	High — full body
Power distribution	~70–75% upper body	~60% legs, 20% back, 20% arms
Key technique driver	Hip hinge depth and lat engagement	Leg-back-arm sequencing
When it arrives in race	Station 1 — legs fresh, arms cold	Station 5 — legs pre-fatigued
Elite men target (race conditions)	3:30 – 4:00	3:20 – 3:50
Elite women target (race conditions)	3:50 – 4:20	3:40 – 4:10
Sub-75 men target	4:20 – 4:45	4:10 – 4:35
Sub-90 men target	4:45 – 5:20	4:30 – 5:05
Typical limiting factor	Lat and shoulder muscular endurance	Leg fatigue carry-over from prior stations

The consistent pattern across thousands of HYROX^® results: recreational athletes are 20 to 50 seconds slower at station 1 (SkiErg) than station 5 (Rower) when controlling for fitness level. Elite athletes close this gap through targeted SkiErg conditioning. At the sub-90 and open levels, the asymmetry reflects undertrained pulling musculature — not a deficit in cardiovascular fitness.

Body Position and Its Consequences

The standing versus seated distinction has training implications that go beyond which muscles are used.

On the SkiErg, a standing position means your entire core must work isometrically to stabilise the spine during the downward pull. There is no seat to support you, no leg rest to brace against. Athletes with limited core endurance lose their hip hinge mechanics within the first 300 to 400 metres: the torso becomes more upright, the stroke shortens, and the lats disengage. What looks like cardiovascular fatigue is often a core stability failure.^[3]

On the Rower, the seated position and the footplate strap create a closed kinetic chain. Your feet are anchored; the stroke sequence has a defined start and end. This structure is forgiving in one sense — the machine does not let you cheat the leg drive as much as the SkiErg can let you cheat the hip hinge. But it creates a different vulnerability: athletes who arrive at station 5 with accumulated leg fatigue cannot simply swap to an arm-dominant strategy the way they might on a machine with less leg dependency. Rowing with dead legs produces a catastrophic split loss.

For technique guidance specifically for the rowing station, rowing technique for HYROX^® covers the full mechanics of the drive and recovery under race conditions. For SkiErg-specific technique, SkiErg technique drills provides structured correction work for the hip hinge and lat engagement.

Energy Demands: Where Each Machine Taxes You

Both stations cover 1,000 metres at competitive effort, placing both squarely in the high-intensity aerobic zone. At race pace, a sub-75 athlete will sustain heart rates of 165–185 bpm on the SkiErg and approximately 160–180 bpm on the rower — similar cardiovascular stress, different metabolic context.

The SkiErg at station 1 hits at the worst possible moment for the upper body. You have run 1,000 metres and your cardiovascular system is already primed, but your lats and shoulders have done essentially no work. The combination of high heart rate at arrival plus cold upper-body musculature means the aerobic supply chain to the arms and lats is not yet optimal. Athletes who have not specifically trained lat and shoulder endurance find themselves in a local muscular fatigue failure well before their cardiovascular system is the limiting factor. This is why SkiErg training — not just running to build aerobic base — is irreplaceable for station 1.

The Rower at station 5 presents the opposite challenge. Your cardiovascular system is under sustained load, your legs are carrying fatigue from three prior functional stations, and you now need to execute a leg-dominant movement for 1,000 metres. The aerobic capacity is not the problem. The problem is local muscular fatigue in the quads and hamstrings, which reduces the power output available from the stroke's most important phase — the leg drive. Training the rower after pre-loading with simulated prior-station fatigue is, for this reason, far more race-specific than training it fresh.^[4]

The practical implication: building a large aerobic base benefits both stations, but it does not solve the specific problems each machine presents. Those require machine-specific training under race-adjacent conditions.

Technique: What Actually Costs You Time

Most athletes lose time at these stations not from lack of fitness but from specific technique errors that reduce their watts per stroke. Fix the mechanics and pace improves without any change in fitness.

SkiErg Technique Errors

Arm-first initiation is the single most costly SkiErg error. Pulling with the arms before the hip hinge is established costs approximately 30 to 40% of potential force per stroke by eliminating the lat engagement that drives the most powerful phase of the pull. The stroke degrades into a shallow triceps exercise, which fatigues the smaller arm muscles rapidly and produces a poor split.

The correct sequence: arms overhead at full extension, then torso drops forward via a hip hinge, then the lats engage and the arms follow through — finishing with hands past the hips, not stopping at the waist.

Shallow hip hinge is the second most common error. Athletes who do not commit to a full forward lean — ideally reaching 45 degrees or more of torso inclination during the drive — shorten the effective stroke length and reduce the mechanical advantage of the lats. Every centimetre of additional hip hinge depth adds watts to the stroke without adding strokes per minute.

For beginners or those new to the SkiErg, SkiErg for beginners provides a progressive programme for building correct mechanics from the ground up.

Rower Technique Errors

Shooting the hips — where the hips rise before the handle moves at the catch — is the defining rowing error in HYROX^®. The seat travels backward while the handle barely moves. This breaks the kinetic chain, wasting the most powerful phase of the drive (the initial leg push) and converting leg strength into seat movement rather than chain tension. The drill to fix it: keep the arms straight and think "push through the heels" before the back begins to lean.

Arm early pull mirrors the SkiErg error: the arms begin bending before the back has reached its full layback. The sequence collapses under fatigue. When athletes feel they "cannot hold pace," the first thing to check is whether the sequence has broken down — not whether they need to increase effort intensity.

Stroke rate matters too. The optimal HYROX^® rowing rate for most competitors is 22 to 26 strokes per minute. Higher rates shorten the drive and reduce power per stroke; the goal is always to maximise metres per stroke, not strokes per minute.^[5]

For beginners working on the rowing stroke, rowing for beginners builds the four-phase technique from scratch.

Why Training Only One Is a Mistake

This is the point most athletes miss: the two machines do not train each other.

Running transfers to the rower in the sense that aerobic capacity carries over. Gym strength transfers to the SkiErg if you have developed lat and shoulder strength. But neither the SkiErg nor the rower is a substitute for training the other machine directly. The movement patterns are too different, the muscle recruitment profiles are too distinct, and the positional demands are too specific.

If you only train the rower: Your station 5 performance is strong, but station 1 becomes a bottleneck. The lats and shoulders arrive at the SkiErg undertrained. Fatigue accumulates in the pulling muscles within the first 400 metres. You lose 30 to 60 seconds you will not recover. Worse, fatigued pulling musculature after a hard SkiErg effort compromises the sled pull and rowing technique later in the race.

If you only train the SkiErg: Your upper-body endurance and station 1 execution improve, but the SkiErg's aerobic carryover to the rower's leg-dominant power production is minimal. A strong SkiErg athlete with no rower training will experience technique collapse at station 5 as the sequencing falls apart under the combined fatigue of four prior stations.

The asymmetry in carryover is real and important. Rowing (full-body, high muscle mass) provides more systemic aerobic benefit than SkiErg training — it builds the cardiovascular base that partly serves the SkiErg. But SkiErg training builds upper-body endurance that rowing does not replicate, because the rower's leg-dominant drive pattern leaves the lats and shoulders comparatively undertaxed. You cannot row your way to a strong SkiErg; you can only SkiErg your way to a strong SkiErg.

The result: athletes need structured work on both machines, with training volume weighted toward whichever is their weaker station. For most recreational HYROX^® competitors — particularly runners and gym athletes — that means more SkiErg work, not less.

For a full plan covering both machines within a structured HYROX^® block, the HYROX^® training plan and HYROX^® workout guide provide week-by-week programming frameworks.

How to Programme Both Machines Together

The following framework integrates SkiErg and rowing training by athlete goal and background.

By Goal

Goal	SkiErg Volume	Rower Volume	Combined Sessions
Finish HYROX®	1×/week aerobic (15–20 min)	1×/week aerobic (15–20 min)	1×/week alternating intervals
Sub-90	2×/week (1 interval + 1 steady)	1×/week steady-state	1×/week combined brick
Sub-75	2×/week (2 interval sessions)	2×/week (1 interval + 1 steady)	1×/week combined brick
Sub-60	3×/week (2 interval + 1 long)	2×/week (2 interval sessions)	2×/week combined bricks

By Background

Running or triathlon background: Aerobic base is strong. The gap is lat and shoulder endurance on the SkiErg. Prioritise SkiErg work for the first four to six weeks, adding rower sessions to complement. Two SkiErg interval sessions per week for six weeks typically produces 15 to 30 seconds of improvement at station 1.

CrossFit or strength background: Pulling strength exists, but machine-specific technique may be absent on both. Build SkiErg mechanics first (two to three technique-focused sessions), then add rower volume. The rower is often quicker to dial in for CrossFit athletes due to prior posterior chain development.

Rowing or erging background: Station 5 is likely strong. Station 1 is the gap — the SkiErg's standing position and upper-body-dominant pattern feel foreign to rowers accustomed to the seated drive. Structured technique work on the SkiErg, followed by interval progression, closes most of the performance gap within six to eight weeks.

The Combined Brick Session

A combined brick — completing SkiErg intervals followed immediately by rower intervals — is the most race-specific training format available. It builds the machine-to-machine transition and conditions the body to shift from upper-body-dominant pulling to full-body leg driving under fatigue.

A simple version: 3 × (500m SkiErg at race pace + 500m row at race pace) with 2 minutes rest between rounds. The transition between machines should be brisk — 30 to 60 seconds maximum. This mirrors the pace of transitions in a HYROX^® race and builds the psychological pattern of shifting gears between two very different movement demands.

Frequently Asked Questions

Which machine should I train more if I am new to HYROX^®? If you have a running background with limited upper-body training, prioritise the SkiErg. Most new HYROX^® athletes have reasonable aerobic capacity and leg strength from running, but genuinely underdeveloped lat and shoulder endurance. The SkiErg gap is bigger, arrives first in the race, and cascades into subsequent stations. Two dedicated SkiErg sessions per week for six weeks will close more of the total race gap than equivalent time on the rower.

Can I use the SkiErg to improve my rowing, or vice versa? Yes, but the transfer is asymmetric. Rowing improves the SkiErg aerobically — building the cardiovascular and posterior chain base that supports the station 1 effort. SkiErg training improves the rower primarily through lat and shoulder endurance gains but does not train the leg drive that generates 60% of rowing power. Neither is a replacement for the other. Train both specifically.

What damper setting should I use for each machine in HYROX^®? For the SkiErg, damper 3 to 5 is the recommended range for most athletes. Higher settings compound arm fatigue quickly over 1,000 metres. For the Concept2 RowErg, the equivalent drag factor of 110 to 130 (approximately damper 3 to 5 depending on machine condition) is standard for HYROX^® racing. Both settings should be tested in training and locked in before race day — arriving at a machine you have never tested at race damper is a preventable mistake.

Why am I so much slower on the SkiErg than the rower? Upper-body muscular endurance. The lats, triceps, and shoulders fatigue before the cardiovascular system reaches its limit because those muscles are undertrained relative to the legs and aerobic system most athletes develop through running and gym work. This is a fixable problem with six to eight weeks of targeted SkiErg training. It is not a general fitness issue.

How do I pace both stations correctly on race day? For the SkiErg, start conservatively — the first 200 metres should feel almost easy. Going out hard at station 1 produces early lactate accumulation that costs time at stations 2 through 4 before you ever reach the rower. For the rower, focus on maintaining stroke sequence over split target: by station 5 your legs are fatigued and form will degrade. A consistent 500m split at race pace is worth more than a fast opening split followed by a mechanical collapse in the back half.

Sources

1. Power distribution estimates for the SkiErg double-pole stroke are derived from biomechanical analysis of cross-country skiing double-pole technique, which the Concept2 SkiErg replicates. Studies of Nordic skiing kinematics consistently identify the latissimus dorsi as the primary force producer, with the triceps brachii and anterior deltoid as secondary contributors. Leg contribution is primarily through the hip hinge and partial knee bend, not a true drive phase — making it meaningfully different from the rowing leg drive that produces the majority of rower power output. ↩

2. The 60/20/20 power distribution in rowing — 60% legs, 20% back, 20% arms — is a standard coaching reference derived from biomechanical analysis of the rowing stroke. It reflects the contribution of each body segment during a full-effort, technically sound stroke. Beginners typically over-weight the arms (commonly inverting the ratio to something closer to 20/20/60), which is both slower and more fatiguing. The coaching priority for any new rower is to establish correct leg-dominant sequencing before adding intensity. ↩

3. Core stability failure under sustained SkiErg loading is documented in sport science literature on the double-pole technique. The transverse abdominis and oblique muscles must maintain intra-abdominal pressure across hundreds of repetitions to preserve the hip hinge mechanics that drive lat engagement. Core fatigue preceding peripheral arm fatigue is common in untrained athletes and produces a visible breakdown in stroke efficiency — the torso becomes progressively more upright and the stroke shortens as the session continues. ↩

4. Post-fatigue rowing adaptation refers to the physiological and neuromuscular changes that occur when the rowing stroke is practised under accumulated metabolic stress. Research on complex training and sequential exercise protocols shows that performing a movement under pre-fatigue conditions — as opposed to always practising fresh — builds both the motor pattern resilience and pacing judgment required for competition. For HYROX^® station 5 specifically, practising the row after a moderate cardiorespiratory challenge at least once per week in the six weeks before a race is the most direct simulation of race conditions available. ↩

5. The 22 to 26 strokes-per-minute recommendation for HYROX^® rowing reflects the optimal balance between stroke completeness and cardiovascular demand for athletes in the 3:45 to 5:30 per 1,000m range. Higher stroke rates (28+) shorten the drive phase and reduce metres per stroke; at competitive effort levels this produces more total work per minute from the cardiovascular system without a proportional gain in boat speed. The target should always be the highest metres-per-stroke number the athlete can sustain at their target split — not the highest stroke rate. ↩
