How Should You Set the SkiErg Damper and Stroke Rate?.

On the SkiErg, a damper setting between 5 and 7, and a stroke rate at 1000-meter race pace of 32-38 strokes/minute , give the most efficient result for most HYROX athletes. The damper doesn't make the machine heavier; it changes the amount of air coming in, which changes the feel of each stroke and how fast the flywheel spins down. The right setting is where the work you produce per stroke meets your capacity to sustain that work for 1000 meters; that point varies from person to person and can only be found by testing.

What does the damper actually do?

Inside the SkiErg is a spinning flywheel and a cage around it through which air flows in and out. The damper lever adjusts the opening of this cage. If the opening is large (high damper), more air reaches the flywheel, it slows down faster, and you have to apply more force on each stroke to speed it back up. If the opening is small (low damper), the flywheel holds its speed longer and the stroke feels light, but you need a higher stroke rate to build momentum.

The practical meaning: the damper doesn't change the load ; it changes the load's character . A high damper creates strength-dominant work; a low damper creates speed-dominant work. The distance and split you see on the screen come from the same physics calculation in both cases — the machine measures the work you produce, regardless of where the lever is set.

That's why there's no such thing as “setting the damper to 10 to finish faster.” At 10, each stroke produces more work, but the recovery time lengthens and muscle fatigue arrives sooner. Since the SkiErg is the first station in HYROX, you pay the bill for that fatigue over the next seven stations. If you haven't settled the basic technical pattern yet, we recommend first reading the SkiErg technique article .

Who should work in which damper range?

Three factors determine the choice: body weight, upper-body strength, and your aerobic capacity. A heavy, strong athlete easily increases the work they can produce per stroke at a high damper; a light, aerobically dominant athlete gets better results holding rhythm at a low damper.

Use the table as a starting point, not a prescription. There's one point that's especially important for beginners: a high damper seems to reward bad technique, because brute force can produce a good split on the screen. But that pattern collapses at 400 meters.

A protocol to find your own optimal setting

Determine your damper choice not by guesswork but with a simple test completed in a single session. For the test, you need to be rested and to have warmed up the machine well; do the 12-minute warm-up routine beforehand.

1. Warm-up: 5 minutes of easy SkiErg, damper 5, free stroke rate. Then 3 x 20-second accelerations with 40 seconds easy between.
2. Block 1 — damper 4: 500 meters, a notch above race pace. Record average split, average watts, and stroke rate. 4 minutes of full rest.
3. Block 2 — damper 6: The same 500 meters, with the same target perceived effort (RPE). Record the data. 4 minutes of rest.
4. Block 3 — damper 8: Same protocol, same RPE. Record the data.
5. Comparison: See at which damper setting your best split came at the same perceived effort. Between two settings with less than a 2-second difference, choose the lower one.
6. Validation: Pull 1000 meters at the winning setting in your next session. If your pace doesn't drop at 500 meters, the setting is right. If it does, go down one notch.

The most important rule of the test is keeping effort constant; if you chase the clock, the three blocks can no longer be compared. Use the RPE scale to standardize effort; we explained how to use it in our pacing control article . If you don't record your results, you won't remember them six weeks later; you'll find which data to track in our training log article.

Damper lever or drag factor?

The number on the damper lever isn't an absolute value. The fan cage collects dust over time, and the machine responds differently at different altitudes and humidity levels. That's why damper 6 in two different gyms may not give the same resistance. If you can see the drag factor on the machine's monitor, that's your real reference: the lever position may change, the drag factor number doesn't.

Here's the practical approach: run the test protocol on the machine at your own gym and note the drag factor at the winning setting. When you get on a machine at an unfamiliar gym or at the race venue, set the lever so it comes close to that value. If you can't access this on the monitor, take 20-30 warm-up strokes and move one notch up or down based on stroke feel. That's more reliable than blindly trusting the number.

A word of caution: don't waste time on this fine-tuning. For most athletes, a one-notch damper deviation costs only a few seconds over 1000 meters. You can lose thirty seconds in the same piece with a poor stroke pattern or a start that's too fast. The order of priority is always technique, then pacing, and settings last.

The trade-off between stroke rate and stroke length

Think of the formula that determines your time in simple terms: the power you produce is the work per stroke multiplied by the number of strokes. You can produce the same power with long strokes at 30 spm or short strokes at 44 spm. The difference is that the second option drives up your heart rate and oxygen debt much faster.

In practice, use these thresholds:

• 28-32 spm: Strength-dominant work, high damper. Long, powerful strokes. Can be race pace for heavier athletes.
• 32-38 spm: The race band for most HYROX athletes. Breathing rhythm stays stable and stroke length is maintained.
• 38-42 spm: Finishing pace or short-interval band. Hard to sustain for the full 1000 meters.
• Above 42 spm: Almost always a sign that your stroke is getting shorter. The screen moves fast, the distance climbs slowly.

The simplest way to check yourself: watch the stability of your watts, not your stroke rate. If your stroke rate goes up 4 units while your watts stay flat, you're working for nothing.

5 common mistakes and how to fix them

1. Setting the damper to the max. The “harder, therefore better” logic doesn't work here. Fix: run the test protocol and accept the result.
2. Assuming the lever sits in the same place on every machine in the gym. As the fan cage gathers dust, the same lever position feels like different resistance. Fix: check the drag factor if possible, not the number on the lever.
3. Mistaking stroke rate for a pace indicator. A high spm can reflect short strokes rather than effort. Fix: manage by split and watts.
4. Using a low damper in training and a high one on race day. You should never try any variable for the first time on race day. Fix: do every SkiErg session in the final 4 weeks at your race setting.
5. Treating the damper as a fix for a technique problem. If you're cutting the end of your stroke short, no setting will fix it. Fix: lock in the movement pattern first, then fine-tune the setting.

4 accessory drills that support your damper setting

• 10 x 15 max-power strokes at damper 8: 60 seconds of rest between sets. Increases the work produced per stroke and helps you take longer strokes at a lower damper too.
• 5 x 2 minutes at a steady spm at damper 4: Rhythm and breath-control work. Hold your stroke rate at 36 and try to maintain your watts.
• Hip hinge strength: Romanian deadlift or kettlebell swing, 4 sets x 8-12 reps. It's the engine of stroke output at high damper; in our kettlebell program article you'll find sample sessions.
• Rowing ergometer cross-training: 20-30 minutes at an easy pace once a week. It feeds your aerobic base; for a comparison of alternatives non-running aerobic alternatives article in our running guide.

Changing the damper setting by training type

Your race setting should be fixed, but you don't have to do all your training at that setting. Using the damper as a training variable is one of the fastest ways to get better at your race setting.

In strength-dominant sessions, set the damper 2 notches above your race setting and do short, explosive sets: 10 x 15 max-power strokes with full rest in between. The goal here isn't time but the highest possible work per stroke. This work lengthens your stroke at race setting.

In aerobic base sessions, drop the damper 2 notches and pull long, unbroken blocks at a low stroke rate: 3 x 8 minutes at 28-30 spm. This builds breath control and movement economy. The Zone 2 logic and where this block fits in in the Zone 2 training article in our running guide.

In race simulation and specific preparation sessions, use only your race setting. In the final four weeks before the race, you shouldn't do a single SkiErg session at a different damper; the feel of the movement needs to become automatic.

What will you do on race day?

There's no decision-making moment in the race, only a checking moment. When you reach the machine, glance at the damper lever for a second, fix it if it's off, grab the handles and open the first 100 meters 3-4 seconds slower than your target split. Settle into pace by 200 meters, raise your stroke rate by 2 at 800 meters and finish in the last 100. Checking in four 250-meter windows instead of constantly staring at the screen keeps your heart rate more stable.
