The abdominal core muscles play a huge role in stability and maintaining balance during a ski. Each technique works some muscles more than others, but the core is always at work. Obtaining proper balance on the skis is the beginning step of Nordic skiing. Double poling works the upper body and core while skating and classic techniques more so works the lower body and core. Double poling works the core primarily because the trunk is constantly moving from flexion to extension. During classic and skating techniques the abdominals are working because the core is always maintaining dynamic balance through the movement of all the extremities. In addition to the abdominals, the pectorals are in constant use to push the poles away from the body propel your body forward.
Without the powder on the ground, skiing can be a difficult sport to keep up year round and to maintain the proper musculature. Roller skiing is an obvious off-season training regimen, but keep in mind other activities aid in maintaing core strength. For example, swimming is a great way to maintain the muscles you need during the skiing season. Not many sports can claim to be a full body workout, but both swimming and skiing fit the bill. Both of these sports require a strong core to be successful. Also, other major muscles used in skiing are also used in swimming like deltoids, lats, triceps, and muscles in the core in addition to the large muscle groups of the legs. Find what works for you!
