Ski Erg: How to Stop Wasting Energy on Station One

The catch position is the starting point of each stroke. Both arms are fully extended overhead, gripping the handles. The body is upright. The feet are hip-width apart or slightly narrower. The knees are soft, not locked. The core is braced. The shoulders are packed down and back rather than shrugged toward the ears. This is the position the body returns to after every stroke.

The initiation of the pull uses the lats to begin pulling the handles downward from overhead. At the same time, the hips begin to hinge forward. The sequence is lat pull and hip hinge beginning simultaneously, not sequentially. Pulling first and hinging second, or hinging first and pulling second, both waste the force potential of the coordinated movement. The coordination is what produces efficiency.

The mid-stroke is the power phase. As the handles pass face height, the hip hinge accelerates. The torso goes from upright to leaning forward at roughly forty-five to sixty degrees from vertical. The arms continue pulling the handles down along the body. The core transfers the force from the hip extension to the arm pull. At this point in the stroke the whole body is contributing to the downward pull of the handles.

The finish position has both handles at hip level, arms fully extended downward, torso at maximum forward lean. The glutes and hamstrings are contracted from the hip hinge. The lats and triceps have completed their pull. Hold this position for a brief moment, just long enough to feel the full extension before recovering.

The recovery phase brings the body back to the catch position. The arms extend upward, the hips return to upright, and the torso follows the arms back to vertical. The recovery should be controlled but not slow. A rushed recovery that does not reach full arm extension overhead loses power on the subsequent stroke. A sluggish recovery extends the stroke cycle time and reduces the number of strokes per minute. Find the rhythm that allows full extension at the catch without wasted time in the recovery.

Stroke rate for one thousand metres in a Hyrox race: between forty and fifty strokes per minute for most recreational competitors. Elite competitors operate at fifty to sixty strokes per minute with significantly higher power per stroke. Test your natural stroke rate in training and set a target before race day rather than discovering it by feel during the race.

The ski erg one-thousand-metre split in a Hyrox race is almost always slower than the same one thousand metres completed fresh on a ski erg in training. You arrive after one kilometre of running. Your cardiovascular system is already at sixty to seventy percent of maximum heart rate. The first thirty strokes at race effort push you toward ninety percent heart rate almost immediately.

The pacing strategy that produces the best overall race result is not the strategy that produces the fastest ski erg split. It is the strategy that produces a fast ski erg split with the least possible cardiovascular and muscular cost to subsequent stations. These are different targets and the difference is worth understanding explicitly.

A negative split approach on the ski erg, starting at moderate effort for the first two hundred metres and building effort through the final eight hundred, produces a slower ski erg time than a flat-effort approach but leaves the cardiovascular system at a lower peak load entering the sled push. The two to three percent time cost on the ski erg is typically recovered through better performance across the seven remaining stations.

If a time target exists for the ski erg, calculate the target stroke rate and pace per hundred metres before the race and hold those numbers from the start rather than starting by feel. Feel is unreliable at station one because the running-induced heart rate elevation makes the early ski erg strokes feel harder than they are at equivalent power output. Trusting the pre-planned numbers rather than feel produces more consistent splits.

The final one hundred metres of the ski erg can be completed at maximum effort because the sled push that follows is not cardiovascularly demanding in the same way. The sled push elevates heart rate through leg effort rather than cardiovascular effort, which means a slightly elevated cardiovascular load entering the sled push is less costly than the equivalent load entering a run or the rowing station.

Three types of ski erg sessions address the different qualities the race demands: technique sessions, pace sessions, and race-simulation sessions.

Technique sessions: low intensity, high attention. One thousand metres broken into two hundred metre intervals with technique cues as the focus. Record video from the side to assess hip hinge depth and arm extension at catch and finish. Technique sessions are done fresh, before any other training in the session, and at no more than sixty percent effort. The goal is motor pattern quality, not cardiovascular stress. Two technique sessions per week in the first four weeks of Hyrox preparation.

Pace sessions: one thousand metre intervals at target race pace with two minutes rest between reps. Three to five reps per session. The target pace should be the pace that produces the goal split time for the ski erg station in the race. Pace sessions teach the body what race pace feels like and confirm whether the target is achievable at the current fitness level. One pace session per week from weeks five through ten.

Race simulation sessions: one kilometre on the treadmill at race running pace, immediately followed by one thousand metres on the ski erg at race effort, immediately followed by the sled push and pull at race weight. The transition from running to ski erg to sled is the specific race sequence. Training the transition trains the physiological and technical adaptation to the combined demand. One race simulation per week from weeks seven through eleven.

Stroke rate training: one session per week of high-stroke-rate intervals. Thirty seconds at maximum stroke rate, thirty seconds recovery, ten rounds. This builds the neuromuscular capacity to sustain higher stroke rates than comfortable without technical breakdown. Stroke rate training is specifically useful for competitors whose natural comfortable stroke rate is below forty strokes per minute and who need to increase it to hit time targets.

A common training error is always rowing one thousand metres as the session. This produces one-thousand-metre fitness but not the race-specific capacity for one thousand metres after running. Always precede at least one weekly ski erg session with a run, even if the run is only five minutes on the treadmill, to begin adapting to the combination that the race demands.

Arms-only pulling: the most common and most costly error. The hips stay relatively upright throughout the stroke and the arms do all the work. Visible sign: the torso stays relatively upright even at the bottom of the pull. Fix: exaggerate the hip hinge until it feels excessive. Video from the side will confirm whether the hinge is reaching the target depth. The correct depth feels like bowing deeply toward the floor.

Incomplete arm extension at the catch: the arms do not fully extend overhead before the next pull begins. This shortens the effective stroke length and reduces the power per stroke. The wrists and handles should reach clearly above the head at the catch. If the arms stop at ear height, the stroke is losing the initial lat engagement that sets up the power phase. Fix: consciously reach the handles as high as possible at the catch and pause briefly until full extension is achieved.

Pulling the handles too far back behind the body at the finish: some athletes pull the handles past the hip line and behind the body in an attempt to generate more power. This does not add power. The lats and triceps lose mechanical efficiency once the handles pass the hip line. Fix: finish with the handles at the hip, not behind it. The power is produced on the path from overhead to hip. Everything after the hip is wasted movement.

Inconsistent stroke rate: the stroke rate drops significantly in the second half of the one thousand metres as fatigue builds. A consistent stroke rate with slightly reduced power per stroke produces better overall time than a declining stroke rate with consistent power per stroke. Fix: set a target stroke rate and use the machine display to hold it. Allow power to reduce slightly to maintain rate before allowing rate to drop.

Gripping the handles too tightly: white-knuckle grip on the ski erg handles fatigues the forearm flexors and transfers to hand fatigue that compounds into the sled pull at station three. Maintain firm contact with the handles but not a death grip. The handles can be held with a relaxed enough grip that the forearms do not pump up during the one thousand metres. Test this specifically in training by checking forearm fatigue after ski erg sessions.

Both the ski erg and the rowing ergometer appear in Hyrox. Station one is the ski erg and station five is the rower. Understanding the physiological differences helps set appropriate pacing and effort allocation for each.

Rowing involves a leg drive phase where the legs push the body up the slide before the arms and back engage. Approximately sixty percent of rowing power comes from the leg drive and forty percent from the upper body. The ski erg has no leg drive component. The power comes from the hip hinge and arm pull. The leg contribution is smaller in the ski erg and the upper body contribution is larger.

This difference means the ski erg is more demanding on the upper body per unit of power output than rowing. Athletes who are good rowers but have limited upper body endurance typically find the ski erg more difficult than rowing at equivalent effort levels. Athletes with high upper body strength and limited leg power typically find the ski erg more accessible than rowing.

The cardiovascular demand of the ski erg is slightly lower than rowing at equivalent power outputs because the total muscle mass involved in the ski erg is smaller than in rowing. This lower cardiovascular ceiling means the ski erg can be performed at a higher percentage of maximum power without the same cardiovascular stress that rowing at equivalent power would produce. In practical race terms, this means the ski erg can be pushed slightly harder relative to cardiovascular limit without incurring the same downstream cost on subsequent running sections.

Programming both in training is important for Hyrox specifically because the ski erg at station one and the rower at station five require different motor patterns despite superficial similarity. Training one without the other leaves a movement pattern gap that appears on race day when the demands of each are separated by four stations and four kilometres of accumulated fatigue.

Eight-week ski erg training block integrated into Hyrox preparation. Three ski erg sessions per week alongside running and other station work.

Weeks one and two: technique focus. Session A: two thousand metres at comfortable pace with technique cues. Session B: five by two hundred metres with thirty seconds rest, focusing on hip hinge depth. Session C: race simulation, one kilometre run then one thousand metres at moderate effort. End of week two target: hip hinge visible in side video, stroke rate consistent above forty per minute.

Weeks three and four: pace development. Session A: three by five hundred metres at goal race pace with ninety seconds rest. Session B: one thousand metres time trial to establish current baseline. Session C: race simulation at increased intensity. End of week four target: one thousand metres time trial result within five percent of race goal.

Weeks five and six: endurance and race integration. Session A: four by one thousand metres at goal pace with two minutes rest. Session B: thirty seconds on thirty seconds off at maximum stroke rate, ten rounds. Session C: full station one through three race simulation. End of week six target: four consecutive one thousand metre intervals at goal pace with consistent stroke rate.

Weeks seven and eight: race-specific. Session A: one kilometre run plus one thousand metre ski erg at race effort, repeated twice with five minutes rest. Session B: stroke rate endurance, one thousand metres at forty-five strokes per minute target. Session C: full Hyrox simulation. End of week eight: ski erg time within target range at race pace following one kilometre run.

Breathing on the ski erg is mechanically constrained by the stroke cycle. The downward pull of the handles and the forward hip hinge compress the thoracic cavity slightly, which makes inhalation easier at the top of the stroke than at the bottom. Most experienced ski erg athletes inhale at the catch position and exhale through the pull and the finish.

A one-breath-per-stroke pattern at lower stroke rates, below forty strokes per minute, allows full inhalation and exhalation cycles that maintain adequate oxygen delivery. At higher stroke rates, above fifty strokes per minute, one breath per two strokes becomes necessary because the stroke cycle is too fast to complete a full breath on every stroke. Practising the two-stroke breathing pattern at high stroke rates in training prevents the breathlessness that comes from attempting one breath per stroke when the stroke rate increases under race pressure.

The Valsalva manoeuvre, holding the breath during the power phase of the pull, is sometimes used in very short high-intensity intervals but is not appropriate for one thousand metres at race duration. Held breath increases intra-abdominal pressure and assists the core brace momentarily but produces CO2 accumulation over a sustained effort that increases perceived exertion and reduces performance. Breathe continuously on the ski erg.

Nasal breathing during the ski erg is achievable at moderate paces and produces better respiratory efficiency than mouth breathing for some athletes. At higher race intensities, mouth breathing supplements nasal breathing as the demand for oxygen exchange exceeds what nasal breathing alone can deliver. Do not force nasal-only breathing at race effort. Let the body find its natural respiratory pattern for the intensity and focus on the stroke mechanics instead.

The transition from running breathing to ski erg breathing requires an adaptation period of thirty to sixty seconds at the start of the station. The running breathing pattern is rhythmically tied to footstrike. The ski erg breathing pattern is tied to stroke cycle. The first minute on the ski erg after a run involves both patterns competing until the ski erg cycle takes over. This transition is normal and shortens with training experience. Starting the ski erg at a slightly lower effort for the first two hundred metres allows the breathing pattern to establish before race effort is applied.

The standard ski erg grip is a neutral grip with the palms facing each other and the thumbs wrapping under the handles. This is the most mechanically efficient grip for the standard double-pole motion and the grip used by the vast majority of Hyrox competitors.

Some athletes use a looser hook grip where the fingers curl over the handle rather than the thumb wrapping under. This reduces forearm flexor fatigue during longer efforts because the grip tension is distributed differently across the hand. The tradeoff is slightly reduced handle control during the power phase, where the standard grip provides more stability for force transfer.

Gloves on the ski erg divide opinion among Hyrox competitors. Gloves protect the palms from handle friction during long sets and may improve grip security for athletes with smaller hands or hands that sweat significantly under race conditions. The tradeoff is reduced tactile feedback through the handle, which some athletes find reduces their feel for stroke efficiency. Test gloves in training before deciding whether to use them on race day.

Handle tension adjustment: the Concept2 SkiErg handles are spring-loaded and return to the overhead position after each stroke. The return tension is fixed and not adjustable on standard Hyrox machines. At higher stroke rates, the handle return becomes a limiting factor because the hands must move upward with the returning handles rather than allowing a natural arm extension. Practise high stroke rate sessions to develop the coordination for working with the handle return rather than against it.

Both handles should be pulled symmetrically. Asymmetric pulling, where one arm pulls slightly harder or earlier than the other, rotates the body and creates a compensatory lateral core contraction that adds unnecessary muscular work per stroke. Video from behind the athlete during ski erg sessions quickly reveals asymmetric pulling patterns that are almost invisible to the athlete during the session. Correct asymmetric patterns in technique sessions before they become entrenched habits.

Improving the ski erg one-thousand-metre time comes from three sources: technique efficiency, aerobic capacity, and strength endurance in the specific muscles used. All three contribute. Addressing only one or two produces faster improvement in the short term but reaches a ceiling that the other two quality areas determine.

Technique improvements produce the fastest initial gains. A beginner with arm-dominant technique who corrects to hip hinge technique can improve their one-thousand-metre time by thirty to sixty seconds within two to four weeks without any fitness change. This is a technique dividend that is available immediately and costs only the time of dedicated technique sessions.

Aerobic capacity improvements take eight to twelve weeks of consistent training to manifest in performance. Long moderate-intensity ski erg sessions, two thousand to three thousand metres at a comfortable conversational effort, build the aerobic base that supports sustained race-pace efforts. These sessions are not glamorous. They are effective. Two per week in the base building phase is sufficient to drive aerobic adaptation.

Strength endurance improvements come from high-rep lat and tricep work combined with hip hinge endurance training such as kettlebell swings and Romanian deadlifts. The lat pull-down at moderate weight for twenty to thirty reps trains the lat in the contraction range relevant to ski erg. Band pull-downs from overhead mimic the ski erg motion and can be done anywhere with a resistance band. Three sets of fifteen to twenty reps, three days per week, provides adequate strength endurance stimulus alongside the machine-based ski erg training.

A time trial every four weeks provides the clearest progress tracking. Complete one thousand metres on the ski erg as fast as possible following a standard five-minute warm-up, every four weeks throughout the preparation block. The time trial result tells you whether the training is producing the expected improvement and whether the race time target is on track. Without the time trial, improvement is subjective and the race day result becomes unpredictable.

Warm the shoulders up before getting on the machine. Arm circles, band pull-aparts, and five minutes of easy rowing on a Concept2 prepare the shoulder joint for the overhead range of motion and the pulling load. Ski erg pulling from cold is a reliable path to early rotator cuff irritation.

Set the damper. The damper on the Concept2 SkiErg controls the air resistance per stroke. A higher damper setting increases resistance per stroke and reduces stroke rate. A lower damper reduces resistance and increases achievable stroke rate. Race machines are typically set to three to five. Train on the same damper setting used in competition for at least the final four weeks of preparation.

Confirm the session type before starting. Technique, pace, or simulation. The session type determines the effort level and the focus cue for the session. Arriving at the machine without a session plan results in an aimless moderate-intensity thousand metres that builds neither technique nor fitness specifically.

Check the display is showing the metrics needed for the session. For a pace session, monitor split time per five hundred metres and stroke rate. For a technique session, monitor stroke rate only and leave effort untracked. For a simulation, start the monitor and do not look at it until the thousand metres is complete.

Record time, split, stroke rate, and perceived effort in the training log immediately after the session. These four numbers are the data points that tell you whether the training is working and whether the race target is achievable at current fitness.
