Single Arm SkiErg: A Complete Guide
Also called One Arm SkiErg Pull
Quick Intro
Single Arm SkiErg, also called the One Arm SkiErg Pull, is a HIIT exercise performed by standing facing a SkiErg machine, gripping one handle in a single hand and pulling down explosively using a hinging motion from the hips while the free arm remains at the side, alternating arms between sets.
Equipment Needed
Single Arm SkiErg needs a SkiErg machine, the only equipment required and the source of the exercise’s resistance.
Why Single Arm SkiErg Matters
Pulling with one arm calls on the back’s largest muscle (latissimus dorsi) and back of the upper arm (triceps brachii) to drive the pulldown, with the front of the shoulder (deltoid, anterior) and forearm muscles (forearm flexors) supporting the grip and pull. The side abdominals (obliques) and deep core (transverse abdominis) work hard to resist the trunk twisting toward the working side, with the lower back (erector spinae) and glutes (gluteus maximus) driving the hip hinge that powers each pull. Pulling with a single handle adds an anti-rotation core demand that the two-arm version doesn’t ask for, since the trunk has to actively resist rotating toward the side doing the work. That makes this a useful unilateral option for anyone in a rotational or asymmetric sport, not just a harder version of the standard pull. Conditioning is the standout, since a full-body pulling stroke repeated at pace keeps heart rate and energy use high.
When to Do It
Single Arm SkiErg fits naturally into a conditioning circuit or a session built around addressing left-right imbalance, often chosen specifically for the anti-rotation core demand the unilateral pull creates. Two to three sessions a week works, alternating arms sensibly and leaving the shoulders time to recover.
Anyone with a current shoulder, low back or wrist issue should approach this cautiously, since a single-arm pull places more demand on grip and shoulder stability than the two-arm version.
Getting Ready
Standing facing the machine with feet shoulder-width apart comes first. Gripping one handle in a single hand while the free arm rests at the side sets up the pull before the first rep begins.
Resisting the urge to let the trunk twist toward the working arm, rather than allowing rotation through the pull, is the cue that keeps this exercise doing its intended job.
Step-by-Step Instructions
1. The setup. Stand facing the SkiErg with one hand gripping a single handle, the free arm at the side.
2. The hinge. Tip forward a little from the hips as the pull starts.
3. The pull. Pull the handle down explosively, resisting trunk rotation toward the working side.
4. The return. Let the handle return with control as the hips extend back to standing, repeating for the working arm before switching sides.
How Many, How Often
Single Arm SkiErg is dosed by work-to-rest interval, alternating arms between sets so both sides get equal work.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to the single-arm pull pattern | 20 seconds of work per arm, 40 seconds of rest, 4 rounds per side, at a controlled pace. |
| Intermediate | The trunk stays stable through a full round | 30 seconds of work per arm, 30 seconds of rest, 6 rounds per side, at a faster pace. |
| Advanced | Comfortable holding trunk control across a full interval set | 40 seconds of work per arm, 20 seconds of rest, 6 to 8 rounds per side, treating the set as a conditioning benchmark. |
A trunk that stays square, not twisting toward the working arm, matters more here than how hard each pull lands, since rotation through the trunk is what the one-arm pull is there to train against.
Modifications and Variations
Single Arm SkiErg has one alternative.
As an alternative, SkiErg Interval performs the same pulldown pattern with both arms at once, spreading the effort evenly across both sides without the added anti-rotation demand.
Common Mistakes to Avoid
Letting the trunk twist toward the working arm. Allowing the torso to rotate during the pull loses the anti-rotation core demand this exercise is built around. Keeping the trunk square and resisting rotation throughout the pull captures the intended benefit.
Using arm strength alone instead of the hip hinge. Pulling entirely from the shoulder and arm without hinging at the hips reduces the power the pull can generate and shifts load away from the larger hip and back muscles. Driving the pull from a hip hinge, not just the arm, keeps the mechanics correct.
Neglecting the free arm’s position. Letting the free arm swing or drift during the pull adds unnecessary movement that makes trunk control harder to hold. Keeping the free arm relaxed at the side simplifies the anti-rotation task.
Doing far more reps on one side than the other. Favoring the stronger or more comfortable arm across a session builds or reinforces a left-right imbalance. Alternating arms evenly between sets keeps both sides developing together.
After Your Set
Holding a door frame or post with one hand and sitting the hips back lengthens the big back muscle on the side that did the pulling. A seated spinal twist releases the obliques and low back that resisted rotation through the set.
Going Deeper
Progress on Single Arm SkiErg often gets judged by how hard each pull lands, but the test is whether the trunk stays square and resists rotation through the last rep on the fatigued side, not just the first. A powerful pull that comes with visible twisting trades away the anti-rotation benefit this exercise is meant to build.
Someone comfortable with a controlled two-arm SkiErg pull typically holds a stable, non-rotating single-arm pull within the first two to three weeks, and increases pace or reduces rest somewhere in the four to six week range.
How to Know You’re Improving
- A trunk that stays square through every pull, without visible rotation
- A hip hinge, not just arm strength, driving each pull
- Roughly even effort and rep quality maintained on both sides
- A faster interval pace attempted only once trunk control stays fully consistent
A trunk that stays square through the last rep, not how hard the pull lands, is what progress looks like here.
Muscles Worked
- Latissimus Dorsi (the broad muscle of the mid and lower back, pulling one handle down with no second arm to share it)
- Anterior Deltoid (the front of the shoulder, reaching the single arm up to the top of each stroke)
- Obliques (the muscles along the sides of the waist, resisting the rotation one-sided pulling creates)
- Triceps Brachii (the back of the upper arm, extending the working elbow to finish the pull at the hip)
- Erector Spinae (the muscles running along the length of the spine, controlling the hinge under an uneven pull)
- Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, holding the hips square to the machine)
- Gluteus Maximus (the largest glute muscle, extending the hips to return to standing between strokes)
- Forearm Flexors (the muscles of the inner forearm, holding a single handle that carries the whole load)
FAQ
What’s the main difference between this and the two-arm SkiErg? This version pulls with one handle at a time, adding an anti-rotation demand on the core as the trunk resists twisting toward the working side, something the two-arm version doesn’t ask for.
Why would a rotational-sport athlete choose this over the two-arm version? Because the unilateral pull and the anti-rotation core demand it creates carry over more directly to sports built on asymmetric or rotational movement than a symmetric, two-arm pull does.
Should both arms get equal work in a session? Yes, alternating arms evenly between sets keeps both sides developing together rather than reinforcing an existing left-right imbalance.
Is the hip hinge as important here as on the two-arm version? Yes, driving the pull from a hip hinge keeps the power output and mechanics consistent with the two-arm pattern.
