Double poling is reshaping the World Cup: why pure upper-body power can match the diagonal stride on grades up to 10 percent.
The honest answer first: double poling is currently reshaping classic cross-country skiing – today's world-class skiers use it over noticeably more of the course than was standard twenty years ago.
The technique itself is simple to describe: both poles plant simultaneously, no leg push-off at all, with all propulsion coming from a powerful upper-body crunch – core and arms work like a spring releasing explosively. Unlike the diagonal stride, which depends on your ski's kick zone, double poling works on any glide base.
That's exactly what makes it so efficient: on climbs up to roughly 8 to 10 percent grade, pure double poling is biomechanically at least equal to the diagonal stride, often more efficient – a figure many underestimate, since double poling feels at first glance like a purely flat-terrain technique. Specialized long-distance skiers now train up to 50 percent of their total volume using double poling, compared to roughly 25 percent for all-round skiers – a clear trend toward specialization.
Why the shift? Better trail grooming, stiffer, lighter ski bases, and longer, more efficient poles have made double poling more competitive over the years, even on terrain where the diagonal stride used to be the automatic choice.
Train Smart. Play Hard. – for double poling that means: core strength isn't a nice-to-have here, it's the actual engine of the movement.
Plant both pole tips roughly level with the binding, not far ahead of your body – planting too far forward wastes power without adding propulsion.
The real force impulse comes from the core: brace your abs, fold your upper body forward from the hips, while your arms drive pole pressure into the snow.
A slight knee-bend impulse just before the pole plant supports the motion but doesn't replace core engagement – double poling stays primarily an upper-body movement.
Grades up to 8 to 10 percent are the ideal practice zone, because that's where pure double poling already competes with the diagonal stride – a good way to build a feel for when the technique pays off.
Double poling loads the core and lower back heavily, especially at high training volume (more in the health guide). Build up the load gradually, warm up the core deliberately, and make sure you get enough recovery as you increase volume. Also watch your wrists and elbows — high double-poling volume tends to accumulate overuse strain there.
Train double poling deliberately even off snow – roller skis, or even double-pole imitation drills with short poles on dry ground, build exactly the core strength and timing you'll need later on snow, regardless of season. A medicine-ball throw crunch simulates the same core impulse when neither skis nor roller skis are available.
On flats and up to grades of 8 to 10 percent, double poling is often equal or faster, because it doesn't depend on the kick zone and, with good core strength, delivers more force per cycle.
Better trail grooming, stiffer ski bases, and more efficient poles have made the technique more competitive over the years — specialized long-distance skiers now train up to 50% of their volume in double poling.
Yes, more than for the diagonal stride. The impulse comes primarily from the core, so the technique benefits heavily from targeted core and upper-body training off the trail.
Yes. Double poling works across techniques because it doesn't depend on a kick zone – it shows up both on the classic groomed lane and on skating sections.
Yes, the movement itself is technically simpler than the diagonal stride, since it needs no single-leg balance on a ski. The real hurdle is strength, not coordination – without enough core strength, you'll quickly run out of endurance to sustain the push over longer distances.
