Short answer: The SkiErg is a vertical air-resistance machine that simulates cross-country skiing’s double-pole technique. It is the only cardio machine that primarily trains the upper body while still delivering elite cardiovascular conditioning. It burns 500–800 kcal/hour, activates the entire posterior chain, and is featured as the opening station of every Hyrox race (1,000 m). For home and box use, the most cost-effective way to own one is via an IRONSIDE bundle: SkiErg + Rower ($1,349), SkiErg + Air Bike ($1,499), or the full 4-machine Combat Cardio Pack.
Key takeaways
- The SkiErg is the only standard cardio machine driven primarily by the upper body and core.
- Burns up to 800 kcal/hour — comparable to a hard run.
- Air resistance scales infinitely with your effort: pull harder = more resistance.
- Zero electricity required, near-zero maintenance.
- Mandatory training tool for Hyrox (1,000 m SkiErg is station #1) and a go-to in CrossFit metcons.
- Excellent low-impact alternative to running for endurance and conditioning.
What is a SkiErg and how does it work?
A SkiErg is a vertically mounted air-resistance cardio machine. You stand facing it and pull two handles downward in a motion that replicates the double-pole technique from cross-country skiing. A flywheel turns inside a perforated cage; the harder you pull, the more air the fan moves, and the more resistance you feel.
This unique design means the SkiErg trains the lats, triceps, core, glutes and hamstrings while delivering high-intensity cardiovascular work — a combination no other standard cardio machine offers.
The 7 benefits of SkiErg training
- Full upper-body cardio — rare and valuable for athletes who already do plenty of leg-dominant work.
- Massive caloric burn — 500–800 kcal/hour at moderate-to-hard intensity.
- Zero impact — safe for runners with knee or hip issues, post-injury rehab, and adults 55+.
- Posterior chain activation — lats, glutes, hamstrings and erectors all fire on every pull.
- Improved cardiovascular base for swimmers, climbers, kayakers and combat athletes.
- Compact footprint — stands vertically against a wall.
- Hyrox-specific — the first station of every Hyrox race is 1,000 m on the SkiErg.
SkiErg vs Rower: which is better?
| Criterion | SkiErg | Rower |
|---|---|---|
| Primary muscles | Lats, triceps, core, posterior chain | Legs (60 %) + back + arms (40 %) |
| Body position | Standing | Seated |
| Footprint | Vertical (very small) | Horizontal (2.5 m long) |
| Learning curve | Easy (5 minutes) | Moderate (2–3 sessions) |
| Best for | Upper-body cardio, Hyrox | Full-body cardio, CrossFit |
The smart answer: own both. The IRONSIDE Rower + SkiErg Combo bundles them at a discount.
SkiErg technique: the 3-phase pull
- Catch: Stand tall, arms extended overhead, core engaged. Slight forward lean from the hips.
- Drive: Hinge at the hips while pulling the handles down toward your thighs. Legs assist with a small bend. Power comes from lats and core, not arms.
- Recovery: Reverse the motion smoothly, returning to full overhead extension. Don't rush it — a controlled return preserves stroke rhythm.
Stroke rate: 30–40 strokes per minute for steady-state work, 40–60 spm for sprints.
The 8 best SkiErg workouts
- Hyrox simulation: 1,000 m for time. Beginner: 5–6 min. Elite: under 3:30. The opening station of every Hyrox race.
- 500 m repeats: 5 × 500 m, rest 1 minute between. Builds anaerobic capacity.
- SkiErg + Burpees: 5 rounds of (250 m SkiErg + 10 burpees). Brutal full-body conditioner.
- 30-20-10 intervals: 30 sec easy + 20 sec moderate + 10 sec all-out. Repeat 5 minutes. Rest 2 min. 3 rounds.
- EMOM 12: Every minute, 15 calories on SkiErg. Rest the remainder. 12 minutes total.
- Death by SkiErg: Minute 1 = 10 cal, minute 2 = 12 cal, minute 3 = 14 cal… add 2 cal each minute until failure.
- Steady-state base: 20–40 min at conversational pace. Builds aerobic base.
- Tabata SkiErg: 20 sec hard + 10 sec rest, 8 rounds. 4 minutes of pure intensity.

Frequently asked questions
What does a SkiErg train?
The SkiErg primarily trains the lats, triceps, core, glutes and hamstrings while delivering high-intensity cardiovascular conditioning. It's the only standard cardio machine that prioritizes the upper body.
How many calories does a SkiErg burn?
500–800 kcal per hour at moderate-to-hard intensity, depending on body weight and effort level. Comparable to running at 9–11 km/h.
Is the SkiErg good for beginners?
Yes. Technique is much simpler than rowing — most people grasp the basic stroke in 5 minutes. Resistance scales automatically to your effort, so beginners and elite athletes can use the same machine at the same time.
SkiErg vs rower — which should I buy first?
If your goal is general fitness or CrossFit, start with the rower. If you specifically train for Hyrox, swim, climb, or want unique upper-body cardio, prioritize the SkiErg. The smart move: buy both bundled.
Does a SkiErg require electricity?
No. SkiErgs use air resistance — the harder you pull, the more resistance. No batteries, no power cord. Just plug-and-play.
How much space does a SkiErg take up?
Very little. SkiErgs mount vertically against a wall (or on a stand). Floor footprint is roughly 50 cm × 50 cm — the most space-efficient cardio machine you can buy.
Is SkiErg good for Hyrox training?
Absolutely essential. The first station of every Hyrox race is 1,000 m on the SkiErg. Regular practice on this exact machine is non-negotiable for race day performance.
Bottom line
The SkiErg is the most overlooked piece of premium cardio equipment. It delivers upper-body conditioning unmatched by any other standard machine, scales automatically to any fitness level, takes minimal floor space, requires no electricity, and lasts a decade-plus with virtually zero maintenance.
For most athletes, the smartest entry point is the Rower + SkiErg Combat Pack ($1,349) — two complementary machines that cover every metcon and Hyrox training need at a bundled discount.
