Extreme Cardio and Core training for CrossFit

You get more fit than you ever imagined possible!

Nordic skiing is the world’s toughest sport measured by endurance, VO2max  and muscle involvement. Inspired by Nordic skiing the ThoraxTrainer indoor skier was build to make this fabulous whole body  training available indoor.

The intense cardio exercise on ThoraxTrainer can help Crossfitters to push their fitness even further! ThoraxTrainer now appears in Crossfit Throwdowns and Competitions such as the Oresund Games in Sweden.



Nordic skiing is on top of the list when it comes to VO2max, because you engage all your muscles in an upright position working at a very high heart rate.

ThoraxTrainer will give you exactly the same, and within a very short time, you will get a significant improvement in your VO2 max.




The versatile training with the ThoraxTrainer is the perfect way to improve the power of your heart. Because you can engage all your muscles at the same time in the ThoraxTrainer, you will have an enormous demand for oxygen and blood circulation in the body.




ThoraxTrainer has a crucial and unique impact on your outer and deeper core muscles. Because the poles are always moved horisontally you have to activate you core muscles, otherwise you will fall. All exercises in the ThoraxTrainer will enage your core muscles.
