There has been a TRX course held on the 7.11.2009 in fitness centre Sonce in Slovenska Bistrica, Slovenia. The guest of the course was Steve Jack from London.
Through the development of the Swiss ball, there were efforts to stabilize it. Therefore a BOSU BALLAST BALL was developed. It allows stable position of the ball that does not roll and it also gives special weight and sound to the ball. It can be used to train balance, torso stabilization and coordination.
