    • PROBLEM TO BE SOLVED: To solve the problem that several kettlebells are required for the training with varied weights because the conventional kettlebells are of a full solid type.
      SOLUTION: A kettlebell is gouged out through from its bottom part to make a cavity and a weight is inserted into a core protruded inward from the lower part of a grip part and fixed with a lock device. The weight is made adjustable and variable, thereby making the training possible with varied weights even in a single body.

    • 要解决的问题:为了解决由于传统的水壶具有完全固体类型而需要用不同重量进行培训的几个水壶的问题。 解决方案:将壶从其底部穿过,形成空腔,将重物插入从把手部分的下部向内突出的芯并且用锁定装置固定。 重量是可调节和可变的,从而使训练成为可能,即使在单个身体中也可以使用不同的重量。 版权所有(C)2007,JPO&INPIT
