Back in the day, Nordic skiers looking for a break from the cold would bolt Concept2 rowing machines to walls and rig them to allow a movement similar to cross-country skiing. Concept2 decided to take that a step further and developed a SkiErg to better accommodate winter athletes indoors.
In Part 1 of this video shot in Vermont, Greg Hammond of Concept2 shows Pat Barber and Jon Gilson how to use the SkiErg. Just like the rowing erg, the SkiErg requires core-to-extremity movement for efficiency, and a few minutes on the machine will leave no doubt that it provides a full-body workout.
In Part 2, Gilson and Barber learn how a biathlon race is conducted. Skiers have to have great endurance, but they also need to be accurate with a rifle while their hearts are pounding. Most biathlons are won at the firing line because a penalty lap for a missed shot can put a first-place skier back in the pack. With Hammond on the stopwatch, the two CrossFitters do an indoor biathlon WOD using a SkiErg and a laser rifle. Instead of penalty laps for missed shots, Hammond has a special consequence for inaccuracy.
