About 7000 liters of blood are transported through the veins back to the heart on a daily basis.  The so-called “calf muscle pump” in the musculature of the leg has the most important function. As the leg moves and muscles contract, the calf muscles pump the venous blood against the force of gravity back up to the heart. Obviously, movement is key to this system working optimally.

Not enough movement and a lack of exercise will result in blockages in circulation. The legs become heavy and start to swell. Vein problems become apparent. kybun training on the kyBounder or the kyTrainer - with or without kyDesk – keeps the vein pump working and the veins strong.
