SkiErg vs Rower in Hyrox

Two Machines, Eight Stations, One Race

HYROX^® places the SkiErg at station 1 and the Concept2 Rower at station 5. Both are 1,000-meter efforts. Both demand aerobic capacity. Both will expose weaknesses you didn't know you had. Yet they are fundamentally different machines that stress the body in different ways — and most athletes are meaningfully stronger on one than the other.

Data from 700,000+ ROXBASE athlete profiles shows a consistent pattern: the majority of recreational HYROX^® competitors are faster on the rower than on the SkiErg, often by 20 to 40 seconds over the 1,000-meter distance. Elite athletes close that gap through deliberate SkiErg training, but at the open and sub-90 level, the asymmetry is stark. Understanding why — and what to do about it — is where race time comes from.

The Mechanical Difference: Upper Body vs. Full Body

The most important thing to understand about these two machines is their muscle recruitment profile.

The SkiErg is primarily an upper-body and core exercise. A proper double-pole stroke begins with hip flexion, engages the lats, triceps, and shoulders through the pull, and relies on core stiffness to transfer force from the torso into the handles. The legs provide a platform — a stable base for the pull — but they are not the engine. On a well-executed SkiErg stroke, roughly 70–80% of power comes from the trunk and arms.^[1]

The Concept2 Rower is a full-body exercise with an entirely different power hierarchy. Legs drive approximately 60% of power at the catch; the back provides roughly 30% through the layback; the arms finish the draw at around 10%. This "legs-back-arms" sequencing means a rower recruits the quadriceps, hamstrings, glutes, spinal erectors, lats, biceps, and core in a single stroke — a significantly larger muscle mass than the SkiErg demands.

More muscle mass means more total power production. This is why most athletes, especially those with a running or strength background, are faster on the rower. Their legs can generate watts; the SkiErg won't let them use those watts the same way.

Race Context: What Each Station Costs You

Understanding the machines in isolation is one thing. Understanding their placement inside the HYROX^® course is what drives smart training and pacing decisions.

Station 1 — SkiErg: You arrive here after a 1,000-meter run. Heart rate is typically 155–175 bpm for competitive athletes. You are in a glycolytic state before you've touched a handle. The SkiErg immediately targets the lats and shoulders — muscle groups that have done zero work on the opening run. For athletes with limited SkiErg-specific conditioning, this mismatch creates early accumulated fatigue that compounds across stations 2, 3, and 4 before the rower arrives.^[2]

Station 5 — Rower: By the time you hit the rower, you have completed the SkiErg, sled push, sled pull, and burpee broad jumps. Your legs are pre-fatigued. This partially negates the rower's full-body advantage — heavy legs mean less power at the catch, which is where most rowing watts are generated. Athletes who have trained the rower with pre-fatigued legs handle station 5 significantly better than those who only train fresh.

The practical implication: the SkiErg punishes upper-body weakness immediately; the rower punishes leg fatigue accumulation. Train for both stress profiles, not just clean, fresh-leg machine work.

Head-to-Head Comparison

Factor	SkiErg (Station 1)	Rower (Station 5)
Distance	1,000m	1,000m
Primary muscles	Lats, triceps, core, shoulders	Quads, hamstrings, glutes, back, arms
Muscle mass recruited	Moderate (upper + core)	High (full body)
Elite men target time	3:30 – 4:00	3:20 – 3:50
Elite women target time	3:50 – 4:20	3:40 – 4:10
Sub-60 men target	4:00 – 4:20	3:50 – 4:10
Sub-90 men target	4:40 – 5:15	4:30 – 5:00
Caloric burn (est.)	Moderate	Higher (more muscle groups)
Technique ceiling	High — form drives economy	High — sequencing matters
Common limiting factor	Lat/shoulder endurance	Leg fatigue carry-over from prior stations
Transferability to running	Moderate (aerobic base)	Moderate (aerobic base)

Elite men are typically 10–20 seconds faster on the rower over 1,000 meters under race conditions. For open-category athletes, the gap can reach 30–50 seconds — almost entirely explained by upper-body endurance deficits on the SkiErg.^[3]

Technique: Where Time Goes in Both Events

SkiErg Technique

The single biggest time drain on the SkiErg is insufficient hip extension. Athletes who bend their elbows early and pull with their arms alone forfeit 30–40% of their potential power output per stroke. The correct movement is:

1. Stand tall with arms overhead and handles at full extension
2. Initiate by hinging at the hip — the torso drives forward and down
3. Arms follow the torso, pulling through with the lats as the hips reach full flexion
4. Finish with hands driving to the hips, not stopping at the waist

The cue that works for most athletes: "drive your hands to your hips, not your chest." The extra arc adds force without adding strokes.

For a full breakdown of technique-to-pace translation, see the HYROX^® SkiErg guide and the SkiErg pace chart.

Rower Technique

Rowing errors in HYROX^® tend to cluster around one mistake: shooting the hips. This is when the hips rise before the handle moves at the catch, breaking the connection between leg drive and upper-body pull. The handle barely moves while the seat travels backward — wasted leg power.

The correct sequencing — legs, then body pivot, then arm draw — must be practised until it is automatic. In a fatigued state at station 5, athletes default to compensatory patterns. Training the sequencing under fatigue is the only fix.

Stroke rate also matters. The optimal HYROX^® rowing rate sits between 22 and 26 strokes per minute for most competitors. Higher rates shorten the drive and reduce power per stroke; lower rates allow full recovery but can drop pace below target.^[4] The goal is to find the rate at which you maximise metres per stroke, not strokes per minute.

Which Should You Prioritise in Training?

The answer depends entirely on your starting point.

If you have a running or strength background but limited machine time: prioritise the SkiErg. This is the scenario that fits most recreational HYROX^® athletes. Runners have aerobic capacity and leg strength; what they lack is lat and shoulder endurance for the SkiErg, which sits first in the race and can derail pacing for all subsequent stations. Adding two SkiErg sessions per week — one interval session, one longer aerobic piece — typically yields 15–30 second improvements at station 1 within six weeks.

If you have a CrossFit or rowing background: your rower is probably already strong. Your gap is likely the SkiErg, for the same upper-body endurance reasons. The SkiErg is also less intuitive for athletes accustomed to rowing; the vertical pull pattern and the absence of leg drive feel unfamiliar. Structured technique work before adding volume will pay dividends faster than just putting in metres.

If you are targeting sub-60: both machines need to be trained together as a system. The SkiErg-to-rower training block — alternating intervals on both machines in the same session — builds aerobic crossover without isolating weaknesses. It also conditions the psychological pattern of transitioning from upper-body to full-body work, which mirrors the race itself.

The 4-week SkiErg training plan and 4-week rowing plan can be run in parallel or on alternating weeks depending on your training volume ceiling.

Aerobic Crossover: Training One to Improve the Other

Both machines build aerobic base. Both stress the cardiovascular system in similar ways at similar intensities. This means training on either machine has measurable transfer to the other — and to your running.

However, the crossover is not symmetric. Rower training builds more total muscular endurance because more muscle groups are under load. Heavy rowing sessions produce systemic fatigue that benefits the SkiErg aerobic system. Heavy SkiErg sessions produce upper-body endurance that does not transfer much to rower power — leg drive remains largely unaffected.

The practical recommendation: use the rower for high-volume aerobic base work; use the SkiErg for race-specific conditioning. A 20-minute steady-state row at zone 2 builds more fitness per unit of time than an equivalent SkiErg effort. But a 4 x 250m SkiErg interval session at race pace is irreplaceable for station 1 readiness.

Both machines also offer a meaningful caloric burn advantage over most other training modalities at the same perceived effort — the rower more so, because of its full-body demand.^[5] Athletes managing body composition for a target race weight can use both strategically.

Programming Recommendations by Goal

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

A combined brick session means completing SkiErg intervals followed immediately by rower intervals without rest between exercises — not between intervals within each set, but between the transition from machine to machine. This mirrors the race's non-stop structure and trains the metabolic pattern of moving between different muscle groups under fatigue.

Frequently Asked Questions

Q: Which machine burns more calories — the SkiErg or the rower? The rower burns more calories per session at equivalent effort because it recruits more total muscle mass. Full-body exercises demand more oxygen, more fuel, and produce more heat. For a 75kg athlete working at a moderate-hard effort, the rower typically burns 10–20% more calories per hour than the SkiErg. That said, both machines provide a high-quality aerobic stimulus; the caloric difference is meaningful for body composition goals but should not dictate which machine gets more HYROX^®-specific training time.

Q: Can I train both on the same day? Yes, and in most structured HYROX^® programmes, you should. Combined SkiErg-rower sessions are among the most effective tools in the training toolkit precisely because they build the machine-to-machine transition that occurs at every HYROX^® race. The key is sequencing: do your harder machine first (typically the SkiErg) and the rower second, matching the race order. Avoid separating the two machines by multiple hours in the same day — the purpose is adaptation to the transition, not recovery between them.

Q: Why am I so much slower on the SkiErg than the rower? Almost certainly because of lat and shoulder endurance. Most recreational athletes spend far more time developing leg strength and cardiovascular fitness through running, cycling, or gym work — all of which transfer well to the rower but not to the SkiErg. The SkiErg demands specific upper-body muscular endurance that is only built through SkiErg training, lat pull-down variations, and similar pulling work. A 6-week targeted programme typically closes most of the gap.

Q: Should I use a high or low damper on the SkiErg and rower in HYROX^®? For the SkiErg, most athletes perform best on damper 3–5. Higher settings increase resistance per stroke, which feels powerful but compounds arm fatigue quickly over 1,000m. For the rower, the drag factor equivalent on a Concept2 is typically 110–130 (damper 3–5 depending on machine condition and altitude). Both machines should be set based on what produces your best pace-per-500m, not what feels most satisfying. Test your optimal setting in training, not on race day.

Q: Does improving my SkiErg also help my rowing, and vice versa? Yes, but asymmetrically. Rowing improvement transfers to the SkiErg aerobically — better cardiovascular fitness and stronger posterior chain muscles help. SkiErg improvement transfers to rowing mostly through improved lat strength and aerobic base, but does not directly strengthen the leg drive that generates most rowing power. If you only have time to train one machine, row for fitness volume and add targeted SkiErg intervals for race specificity.

1. Power distribution estimates for the SkiErg double-pole action are derived from biomechanical analysis of the cross-country skiing double-pole technique, the movement pattern the SkiErg replicates. The upper body and core — lats, triceps, shoulders, abdominals — are the primary power generators; leg contribution is limited to a partial squat initiation in some technique variants but is not the dominant driver. ↩

2. Heart rate data at HYROX^® station transitions reflects average values observed across competitive athlete monitoring. Individual values vary by fitness level, race pace, and environmental conditions. The 155–175 bpm range is typical for athletes targeting sub-75 to sub-60 finish times. ↩

3. The 10–50 second rower advantage over the SkiErg across athlete divisions is based on aggregate performance data from ROXBASE's database of 700,000+ athlete profiles. The gap is largest in the open and recreational categories; elite athletes tend to have more balanced machine performance due to deliberate cross-training. ↩

4. The 22–26 strokes per minute recommendation for HYROX^® rowing is based on performance analysis across competitive divisions. Higher-level athletes may sustain 26–28 spm efficiently; recreational athletes often produce more watts at 22–24 spm due to the longer recovery-drive ratio this allows. ↩

5. Caloric expenditure comparisons between SkiErg and rowing are based on metabolic equivalents (METs) and total active muscle mass estimates. Rowing engages a larger proportion of total body muscle mass than SkiErg double-pole technique, producing proportionally higher oxygen consumption and caloric expenditure at equivalent perceived effort levels. ↩
