To get any closer to cross-country skiing, you'd have to be out on the snow!

“I tried a lot of ski-simulators. ThoraxTrainer™ is the best simulation of real movement on skis. This year is the first year I have incorporated ThoraxTrainer™ into my long-term preparation and initial tests show promising results in my performance level."

The ThoraxTrainer™ has been developed to train and improve strength, endurance, core stability, technique and VO2-max for cross-country skiers.

– 96% correlation with outdoor nordic skiing

– Authentic movement pattern

– Realistic feeling of skiing on snow

– Extreme CORE training

Developed for skiers by skiers

The ThoraxTrainer™ was the first ski-ergometer able to imitate cross-country skiing with a smooth and realistic feeling of skiing on snow.

Authentic Movement Pattern

The ThoraxTrainer™ was originally developed specifically to train and improve strength, endurance, core stability, technique and VO2-max for cross-country skiers.

96% Correlation with outdoor skiing

A research project from Umeå University (Sweden) shows a correlation of 0.96 between the ThoraxTrainer™ and cross-country skiing. In other words, you can predict your performance on skis from your performance on the ThoraxTrainer™ with 96% accuracy.

Monitor your Improvement

The ThoraxTrainer™ is used by professional and leisure skiers who want to benefit from the very efficient training.  The ThoraxTrainer™ computer enables you to evaluate your training and technique in detail, helping you to improve your performance in the ski track.

VO2-max & Endurance

The ThoraxTrainer™ has a very high impact on your cardiovascular system that will improve your VO2max and endurance very quickly to an even higher degree than training on skis or rollerskis.

Core Muscles

The ThoraxTrainer™ also has a high impact on your core muscles that improves your skiing on snow in both the classical and skating techniques. Exercises with double and diagonal poling on one leg at a time will particularly have a huge impact on your core muscles and balance. This will improve your classical technique on the uphill and your skating on the flat and slight uphill.
