Endurance

The plyometric movements of large muscle groups produce an immediate increase in heart rate. On the other hand, in cardiovascular training, by smoothly transitioning from one individual exercise to the next, heart rate remains relatively constant. To achieve the full benefits of endurance training, such as fat-burning, the length of the exercise routine should be never be less than 30 minutes.

In a study conducted in 2007 by the Institute of Medical Physics at the Friedrich-Alexander University of Erlangen-
Nuremberg, the relative effectiveness of various exercises with and without the XCO-TRAINERs was compared, using the respective parameters of heart rate, oxygen intake and energy expenditure. Given a maximal error margin of 5%, the differences were extremely significant and therefore very applicable.

It was proven that by activating arm and upper body musculature, the XCO-TRAINERs increased the intensity of the exercises, which is a factor of great importance in boosting the effectiveness of cardiovascular fitness training. Calorie burning was boosted by 33%., which also resulted in a higher rate of burning carbohydrates and fat. (cf.
