Very good but needs improvement

Have ordered the 10kg Clubbell through Amazon. I have here probably do not explain what can do with them for great things, I'm just saying it is the exercise machine of the 21st century. In the known exercises such as Shield Cast etc tens of small muscle groups that are not reached in normal strength training exercises. Depending on where you take the Clubbell handle more difficult or easier you can make some exercises (more or less leverage). This is a very cool thing. The only downfall to this Clubbell I find very very smooth surface ... just also on the handle. One has too much to do with that one thing that will not slip out of your hand than you could concentrate on the training. Ever in exercises such as one handed Mills for example, the also be quite dangerous. I managed my remedy with a band as you would wrap about tennis racket handles when they are tapped. Average costs 1 Euro per piece. And last forever !!!! Jetz I have a great rubber grip and the club Bell remains bombproof in my hand. Will order me more of the brand and equip them with the tennis tape.
